Diagnose trouble with a residential steam generator

Diagnosis and repair details for electric residential steam bath generator:

This article series describes in detail how, with help from the manufacturer we diagnosed and repaired a new but troubled installation of a residential steam generator in the shower of an existing home.

We explain what went wrong, what trouble it caused, and how steam generator problems with small residential steam generators might be diagnosed and repaired.

Troubleshooting a New Steam Bath Generator: no steam, error messages

Mr. Steam generator H2O Error Message (C) Daniel FriedmanLet me emphasize at the get-go that the Mr. Steam generator and its controls discussed here is in our opinion an excellent product with superior product support.

The trouble we describe: no steam, water at steam head, error messages at the control, is laid entirely at my own feet as the purchaser and contracting-installer of the equipment.

Bottom line: I took my eyes off of the worker with the hammer drill! Eventually we found that one or more wires in the Mr. Steam iTemp control cable had been damaged by a screw driven into the wall. Replacing the control cable fixed the trouble.

The rest is in the details.

Any mechanical system installation that varies from what the manufacturer intended includes a risk that you make a mistake. Having spent nearly 50 years diagnosing problems at buildings and their mechanicals systems I can but emphasize that even if nothing could possibly go wrong, something can and often will.

The property owners tested the new Mr. Steam® generator installation and found it working perfectly after the initial installation. For a few days.

The steam shower, whose enclosing safety glass window and doors were "on order" was sealed for testing using a plastic tarp.

At that time, pending completion of the weather-enclosure the generator, when not in use, was protected by a plastic tarp and was kept successfully dry. Besides, it never rained during that test period.

Steam generator indicator lights for power and water (C) Daniel Friedman

Above: the steam generator control circuit board indicator lights are showing that the unit has power and that it has been properly filled with water.

Then our sheet-metal crew returned to install the weatherproof cover over the steam generator. Thinking that we had plenty of working space, we made a fatal error: we failed to double-check that one of the mounting screws for the steam generator cover might pierce a pipe or an electrical cable.

The site screw drilled pilot holes and screwed the new cover box to the wall. It was a beautiful installation shown at page top and in other photos here.

Observation 1: no steam

The owners tested the steam generator that evening. It failed to operate. Steam was not generated and the wall control displayed two error messages.

The wall control power button and temperature control buttons gave no response.

Observation 2: error messages on the wall control

Err2 was followed by H2O - the unit was not sensing that it had sufficient water.

Mr Steam iTempo steam control module, wall mounted - in San Miguel de Allende steam generator system(C) Daniel Friedman Mr. Steam generator H2O Error Message (C) Daniel Friedman

Error codes are explained in Mr. STEAM GENERATOR MS90EC1 INSTALLATION MANUAL [PDF] where you can read that

Err2 means it thinks the circuit board override-test button has been pressed for more than 5 minutes, suggesting a problem with the control or its cover.

H2O - a warning shown at the start of this article, means that the system is not detecting sufficient water - the manual lists several possible causes.

Was the problem a misadjusted water pressure regulator, a bad water control valve in the steam generator, or something else?

Steam generator power light - green (C) Daniel Friedman

The green light indicates that the steambath generator has electrical power. Notice that the yellow WTR (water) and red HTR (heater) lights are not lit.

Steam generator water sensor and other controls (C) Daniel Friedman

Above: to the left of the control circuit board you'll see the purple wire connected to a water level sensor probe for the steam generator.

Particularly if the system is being fed hard water, mineral deposits accumulating on the probe's sensor tip can interfere with the ability of the sensor to properly measure water level.

Some water level sensor probe models can be cleaned, others must be replaced if scaling trouble is found.

Behind the sensor probe is the black connector power switch for incoming 240VAC.

Control board in Mr. Steam generator installed in San Miguel de Allende (C) Daniel FriedmanWe checked the pressure gauge at the pressure regulator and re-adjusted the regulator to be sure we had about 20 psi of incoming water.

That made no difference.

Observation 3: wall control goes dark

Then the wall control went completely dark, refusing to respond to the on-off switch nor its other controls.

Suspecting that a cover mounting screw might have cut the control wires between the wall control and the steam generator's circuit board we tried the on-board over-ride button on the circuit board.

If all else is working this test will give 5-10 minutes of steam generation.

The test cycle using the over-ride button (red arrow in our photo above) resulted in cool water running continuously out of the steam head (photo below).

Did this mean that a water control solenoid in the steam generator was broken?

Probably not. If the solenoid fails you should see either no water or water running continuously regardless of whether the unit has electrical power or not.

Water runs out of steam head (C) Daniel Friedman

Mr. Steam MS90E Steam Generator Errors: Probable Diagnosis:

Damaged Mr. Steam iTempo control cable wire (C) Daniel Friedman at InspectApedia.comA call to speak with Mr. Steam's technical support representative led to his conclusion that

Watch out: being careless when drilling and mounting anything along the route of piping or electrical control cables that have been routed within a wall cavity risks causing serious damage to the equipment.

In a wood-framed building wiring is normally protected by steel plates if it passes close to the surface of a wall stud.

But in Mexico a common construction method builds out of solid concrete or out of adobe. After walls and ceilings have been constructed it is common practice to cut grooves in the wall surface for pipes or wires.

After pipes or wires have been installed they are plastered-over. Once the building has been painted, the exact path of these pipes or wires may be impossible to see.

Special thanks to the P.R., Mr. Steam's technical support representative who patiently guided us through the trouble symptoms and recommended the necessary repair parts for this steam generator repair work.

Tempo / Mr. Steam Control Error Codes & Actions

Are you sure the display is otherwise working properly?

I ask because the System Status Codes listed by Mr. Steam using the AirTempo controller include

On 2020-04-11 - by (mod) - diagnostic questions and suggestions: error code 23 on Mr. Steam

Error code 23 diagnosis on steam generator

[Click to enlarge any image]

Nick:

Some diagnostic questions and suggestions:

1. In a proper installation there should be NO valve of any kind between the steam generator's outlet opening and the steam opening in the steam room or bath area, so I don't suspect a closed valve.

But I would check the temperature-pressure relief valve on your steam generator for signs of dripping or leakage: that might indicate a scale blockage (or other unsafe condition).

Next:

2. What are the status lights showing on your MS 400 steam generator?

3. Take a look at the troubleshooting excerpt from a Mr. Steam manual that I'll post below ( a link to the manual is in the article above on this page). You'll see that on the control board at position #5 is a small white test button that will force the generator to turn on and produce steam for 10 minutes.

Try that and tell me what happens,

Steam Generator Won't Turn On

On 2021-01-18 by (mod) - If the iSteam (touch screen control) START button is not turning the steam unit on

Mr. Steam offers a large collection of troubleshooting guides at https://www.mrsteam.com/virtual-tech/ where we find this advice that confirms my suggestion to check further for a problem with the controller cable:

When NO lights come on advice in this Mr. Steam troubleshooting illustration is offered

[Click to enlarge any image]

Product: Residential Generators

Problem: iSteam® START Button Not Turning ON

If the iSteam (touch screen control) START button is not turning the steam unit on, an incorrect control cable may be the problem.

1. Go to settings and click “DISPLAY”

2. Bring your brightness down to 10 percent and press SAVE.

3. Go back to the home screen and press the START button. If the steam unit has turned on this could indicate an issue with the control cable. A simple fix to this solution is to install the retrofit cables. (PN 104128).

4. Turn the power OFF to the steam unit at the main breaker.

5. Unplug the control cable at the steam generator side and attach one of the adaptor pieces to the cable.

6. Plug the cable with the adaptor back into the unit.

7. Remove the control from the wall.

8. Unplug the cable from the control and attach the other adaptor piece to the end of the cable.

9. Plug cable with adaptor into the control.

10. Turn power back on at main breaker.

11. Test your control to ensure it turns on at the START button.

12. Reinstall your control on the wall. Make sure to use silicone when installing controller.

When you unplug the iSteam3 the board seems to restart.

Lights go off and come back on about 30 sec later.

On 2021-01-18 - by (mod) -

It's possible that the connector at the control panel or the other end of the cable at the circuit board is not properly connected so that's probably the first thing to check.

Water Won't Feed into the Steam Generator

On 2020-12-18 by (mod) - the red light comes on but no water will enter the generator

Burt,

When the steam control is calling for steam provided the water at the appropriate pressure range has been provided to the steam generator a solenoid valve opens to admit water into the device.

I would be sure that you were providing free flowing water at the proper pressure range specify for your same generator model.

I found for example that we needed to put a pressure regulator in front of many models but I've been involved with.

If You have water at proper pressure, and you have power, and the solenoid doesn't open you could have a wiring error or a damaged control board or solenoid.

On 2020-12-18 by Burt Kay

I have just bought a new steam generator and although the red light comes on no water will enter the generator. Can you me why?

Water Comes out of Steam Head at Steam Generator

On 2021-01-03 by (mod) - When water is flowing out of the steam-head on a Mr. Steam or iSteam unit:

Thomas

`When water is flowing out of the steam-head, Mr. Steam's tech information advises the following:

Product: Residential Generators

Problem: Water Flowing Out of Steamhead on a Mr. Steam generator

Water coming out the steamhead means the steam unit is overfilling.

! WARNING Shock Hazard. Power must be disconnected at the main electrical supply. Remove steam generator covers. Retain screws and covers for reuse.

[Click to enlarge any image]

! WARNING All electrical trouble shooting to be performed by a qualified licensed electrician.

1. Check the Liquid Level Probe.

• Remove top cover to steam unit.

• Located the Liquid Level Probe (looks like a spark plug with a purple wire connected, Fig.1)

• Unscrew the top nut to remove the purple wire (use a 5/16 nut driver).

• Remove the Liquid Level Probe (use a 13/16 socket to remove probe).

• The probe is a stainless steal rod. Clean the rod with an abrasive pad or sand paper. If the rod has a clear plastic sleeve completely covering it, the probe (PN100471-2) will need to be replaced

• Re install the probe with Teflon tape. Make sure the nuts on top of the probe are snug tight.

Adding:

I have not found an explanation for Mr. Steam err5 code in the manuals; you'd need to wade through the frustration of getting tech support on the phone, Thomas, but first look at the advice I posted a moment ago.

On 2020-12-03 - by (mod) - If the PWR (Power) and WTR (Water) lights are both on

Slav

If the PWR (Power) and WTR (Water) lights are both on, that's normal when the steam generator is turned on. The third red light HTR (Heater) only turns on when the steam room control is calling for steam.

But if water is truly always dripping from the steam head then your steam heater's solenoid control valve that opens to allow steam into the room is leaky and probably needs replacement.

I'd check with Mr. Steam before ordering the part.

Steam Generator Won't Turn Off

On 2021-09-20 by Mike: Mr. Steam's Auxiliary Temperature Probe Control Solves Steam Generator Problem

Aux steam temperature sensing probe solves steam room or steam geneartor overheating problem (C) InspectApedia.com MikeMr Steam sent me the aux temperature probe (MSTS). Plugged one end into the Liquid Level Control Board (LLCB) and ran the cable with other end (probe) into the steam room for a test.

Wound the end of the cable twice around the Tempo Control (TC), and let the end of cable with probe dangle in the air. Turned on the steam and everything worked flawlessly.

For the first time in 13 years I was able to regulate the steam temperature by using the up and down arrows on the TC!

Although the reason why the TC probe could never regulate the temperature of my unit will forever remain a mystery, I'm not complaining. Here's a photo of the final installation.

Had to remove some exterior paneling and drill a small hole through the interior ceramic tile.

Used a brass washer as an escutcheon and back filled the probe and adhered the washer to the wall with clear silicon caulk.

@Mike,

Great news and thank you for taking the time to follow up with the update post. That will certainly help other readers.

On 2021-08-24 by inspectapedia.com.moderator (mod) - temperature control does not turn off the steam generator - check control board jumpers first

@Mike,

We'll kick ourselves if all these years it's simply been a wrong jumper placement. Mr. Steam didn't always make those details easy to find but the data should be in the IO manual for your specific Mr. Steam generator model.

Example: Instructions for MS, MX, CT & SAH mr.steam Generator PC Board Replacement include this on jumpers:

Continuing: here, from Mr. Steam's Virtual Tech document (given as a PDF in the article series above)

for the Mr. Steam T-Series we have this detail about jumpers

Mr. Steam T-Series Override:

All electrical trouble shooting to be performed by a qualified licensed electrician.

Shock Hazard. Power must be disconnected at the main electricalsupply. Remove steam generator covers. Retain screws and covers for reuse.

1. Remove top cover to steam unit.

2. There are 3 black plastic jumpers protruding from the bottom left side of the LLCB. (Fig.2)

The jumpers are labeled jmp4, jmp3, and jmp2. Above each jumper is an empty prong.

3. Move the JMP2 (on right) to the empty prong and the middle prong. (Fig.3)

4. Once jumper is moved, the steam unit will start filling up with water.

If unit does not fill you have an issue with the LLCB (PN103899).

If the unit fills and steams up after 5 min, there is a control or a cable issue.

Remove jumper to original location when done testing.

On 2021-08-24 by Mike - Jumper 1 is concerned with maintaining steam room temperature

Took a photo of Jumper 1 located at bottom right corner of the Liquid Level Control Board which for some reason isn't shown in Mr Steam's manual control board illustration.

Supposedly Jumper 1 is concerned with maintaining steam room temperature which, of course, relates to my problem .

Just above Jumper 1 is a black block of 9 pins consisting of Jumpers 4-3-2 (left to right). Could find no loose solders on either end of Jumper 1, including inspecting the back of the board.

On 2021-08-24 by Mike - may need aux temperature sensing probe and cable to control steam generator temperature

Great point. No, I don't have an aux temperature control cable hooked into the liquid level control board, but the Mr Steam people have agreed to send me one.

If and when I get it I'll try it out. I did manage to look up and identify virtually all the wiring installed on the control board, and compared them with mine.

Found no anomalies. I'm including a sketch which identifies most of the wiring plugged into the board. Could not locate P7 and could not figure out P8's function.

On 2021-08-23 by inspectapedia.com.moderator (mod) - wiring diagram for steam generator


@Mike,

Lots of board and wiring photos for Mr. Steam - here's one; not sure if it helps.

Also check for on-board jumpers and dip switches found on some control boards.

On 2021-08-23 by inspectapedia.com.moderator (mod) - steam generator temperature control

@Mike,

I'll look through my photos of my Mr. Steam installation - and will post here what I can find of its wiring. Of course you'll want to review your own wiring connections but it's pretty hard to make a mistake unless the cables themselves are damaged;

That is, the steam generator itself comes with its control board installed; the only direct-wiring I remember was the electrical power connections to the unit; The control harness has a one-way plug-connector at each end so it ought to be hard to make a mistake there.

A problem we had that I've reported in this article series is a damaged control cable - nicked wires - that occurred after the original installation.

Watch out: some Mr. Steam units, particularly depending on the iTemp control's location, use a separate auxiliary temperature control sensor probe that has to have its own connection to the control board. That's needed if the primary steam control panel is located such that it doesn't properly sense steam room temperature.

Is your installation one of those? See the attached detail from the Mr. Steam IO Manual.

On 2021-08-21 by Mike - after replacing parts the steam generator temperature control still not working

It's definitely not a mounting problem. The only other possibility might be to check the liquid level control board wire connections to make sure the proper wire is mated to the proper pin on the board.

Mr Steam initially sent me a replacement board as I mentioned before, but I would have rewired the new board exactly as the old one had been wired.

So if the old one was wired incorrectly to begin with .

See where I'm going? I'm going to try to find a Mr Steam photo with the board fully wired and check it against mine. I'm not sanguine about finding one since it's been 13 years!

On 2021-08-20 1 by inspectapedia.com.moderator (mod)

@Mike,

That's certainly frustrating, I agree. The fact that you have never had proper temperature control from day 1 of installation should be diagnostic. Unless a wire or control component was damaged during installation, you'd figure that the problem may be with the installation itself: after all you've replaced most of the possible parts that could be damaged or defective.

Have you looked carefully at the location and installation of the iTempo control in the steam room to convince yourself that it is not being affected by its mounting location?

On 2021-08-20 by Mike - temperature control won't turn off the steam generator

My Mr Steam is 13 years old. From day one, the Tempo Control never maintained temperature. All it would ever do is turn the steam "on", "off", or "pause". E.g., if I set the temperature at 115, the steamer will continue to run right through 115 to higher temperatures, and won't shut down until I press "off" or "pause"

. Although Mr Steam sent me new cable, Tempo Control, and Liquid Level Control Board, the problem persisted. Any thoughts?

On 2024-01-14 by InspectApedia Publisher (mod) - successful control board replacement & relay repair in old steam generator: LLCB 103899

@Stan,

Outstanding. Thank you for the detailed steambath generator control board upgrade description. We'll be sure to keep it with this article as it will indeed be useful for other readers who have older equipment.

Did you take any pictures of the repair that you could post here?

On 2024-01-14 by Stan

Posted previously that I had an unsupported LLCB 103899 that wasn’t working properly even in bypass mode. Ordered a new set of relays from a seller in China on EBay couldn’t find them on DigiKey

Once replaced the board worked intermittently but sometimes it would just shut off the contactor for the heating element.

Cut the relays open and they all looked fine so that didn’t seem like the problem and what looked like a switch mode power supply had 5v and 3.5v. Checked all the capacitors that looked fine and on a first pass they had the correct values off the board.

Gave up on fixing it with no schematics. Ordered a board for a newer machine 104288 which has the 3 LEDs.

Needed a new controller the itempo type bought both on EBay a prices low enough to be worth trying.

Had to trim the harness and add a molex mini fit jr connector to plug into the new board. Hardest part was running a new cable into an existing shower for the new controller. Tested and it worked perfectly.

Upgraded a 20yr old hardly used machine if anyone else hasn’t posted this already it’s possible and should work if everything else is good. You will have to move the transformer to make room for a larger board. Cheers

On 2023-09-28 by InspectApedia Publisher - auto flush control may be sticking

@Rodolfo Cordon,

It sounds as if an auto flush control is sticking, possibly because of mineral scale that could be cleaned from a part, or, less likely, a failing temperature sensor or relay.

We've managed a similar Mr steam unit for years without auto flush by simply executing a manual flush after the system has been used, turned off, and cooled down a bit. That might be an option for you.

On 2023-09-28 by Rodolfo Cordon

I have a Mr. Steam MS400 that I have been using and lately it has been giving me a problem of just water flushing to the auto flush and taking a while before it stop to start steaming.

It has been doing this lately and I would try to turn it off and on at the main breaker and on at the only switch button to start and it kinda does work until lately it has been taking a long time to start.

I have not done any service at all since I installed it few years back. It is an old model but does heat up quickly and does the work. Any idea on what to do is appreciated.

On 2023-09-27 by InspectApedia-911 (mod) - steam room generator relay circuit on the board may be damaged

@Stan,

So if you can't replace the control board I still wouldn't give up. In a case like this years ago I took my failed relay control board to a friend who was an electrical engineer who worked on circuit boards and he actually replaced the bad component for me.

For someone who knows how to work on circuit boards that's a trivial task but for normal people you more likely to destroy the board if you don't know what you're doing.

On 2023-09-27 by Stan

I called tech support and they thought it was the LLCB board because it still shut off after 30sec with the controller bypassed with a jumper. This is an old unit from after 2003. It has no temp sensor just a water level sensor. It will continue to run until the temp set point is reached.

If I jump 24vAc power directly to the contactor it will continue running and the fill valve works and it will produce steam. With the contactor jumped to power I would have to manually shut it off with a switch. I don’t think that’s a safe solution it was just a test.

No scale in the unit I cleaned it but actually was like new inside. I think the relay circuit on the board may be damaged but visibly don’t see any damage.

On 2023-09-26 by InspectApedia Publisher - Mr Steam MS-65 unit never makes steam

@Stan,

If you think that the actual heating element works then the problem could be a bad temperature sensor. The fix could be something as simple as removing a sensor and soaking it in vinegar to remove accumulated scale.

On 2023-09-25 by Stan

Have a Mr Steam MS-65 unit powers on and fills. The element is energized for about 30seconds and the contractor opens. It never makes steam unless you be power cycle it long enough to get it hot enough.

When the jumper on the far right is moved into bypass mode it does the same and shuts off quickly. The LLCB is 103899 and no longer available. Anyone familiar with board level repair on these or have one?

If there is anything else I can check please let me know.

On 2023-06-11 by InspectApedia Publisher - water level indicator does not light up it goes directly to green

@Charles,

Je suis d'accord que cela semble hors d'ordre. Mais attendez une minute ou deux pour voir si le remplissage d'eau est simplement retardé, comme cela peut se produire si le générateur de vapeur a été rincé après sa dernière utilisation.

Pour les autres:
Charles said:

When I turn on the generator the DS4 water level indicator does not light up it goes directly to green

We replied:

I agree that that sounds out of order. But wait for a minute or two to see if the water-fill is simply delayed as may occur if the steam generator was flushed out after its last use.

A continué:

En fonctionnement normal, lorsque vous allumez le générateur de vapeur DS4, le vert s'allume en premier, indiquant simplement que l'appareil est sous tension. Il peut y avoir un délai dans le voyant jaune-orange pendant que l'appareil attend d'être rempli d'eau. Une fois que l'eau a rempli le chauffe-eau, le voyant rouge s'allume pour indiquer que l'appareil est en mode chauffage.

Si sur votre générateur de vapeur le voyant jaune ne s'allume jamais, le relais ou la vanne d'alimentation en eau peut avoir besoin d'être remplacé.

OU

vous avez oublié d'ouvrir l'alimentation en eau du générateur de vapeur.

Si vous voyez un code d'erreur de H2O
alors
le générateur de vapeur n'a pas détecté
l'eau pendant plus de 5 minutes.

Si vous entendez un fort bourdonnement ou un bourdonnement qui peut indiquer un blocage dans le
ligne d'eau.

Si tel est votre cas, les instructions de réparation se trouvent dans le manuel donné ci-dessus sur cette page.

...

Continued:

During normal operation, when you turn on the DS4 steam generator, green lights up first, simply indicating that the device is powered on. There may be a delay in the yellow-orange light while the unit waits to be filled with water. Once water has filled the heater, the red light will turn on to indicate the unit is in heating mode.

If on your steam generator the yellow light never lights, then the water feed relay or valve may need replacement.

OR

you forgot to turn on the water supply to the steam generator.


If you see an error code of H2O
then
the steam generator has not sensed water for more then 5 minutes.

OR

If you hear a loud buzz or hum that may indicate a block in the water line.

If that is your case, repair instructions are in the manual given above on this page.

On 2023-05-17 by InspectApedia Publisher - steam generator runs for a while then throws the 60A breaker

@Daniel L,

Amps = watts / volts

(roughly)

9000 w / 120v = 75 Amps

So if your steamer is connected connected to a 120 volt 60A circuit, you're drawing more current than that 60 amp circuit can safely provide. Would explain why the breaker is tripping off.

Separately, I agree that connecting the ground in the neutral to the same point anywhere except in the main electrical panel is unsafe and improper.

My Happybuy 9Kw steam generator, that I just installed, runs for a while, then throws the 60A breaker. The breaker is new and the specs call for 60A. The wiring diagram seemed strange as it had the neutral and the ground go to the same post. Any idea what's going on and/or how to repair it?

I have a 2006 S&M 7.5KW EL unit which will fill with water and when activated for steam it sits and time counts down but no steam. I can hit the auto drain feature and the water drains. Any ideas as to what to check.

I have two relays 692-12D-2A22F coil relays that have power on the very end of the relays but nothing going out to the heating elements. The heating element check out as good.

@Dan F,

Apologies that from just your note I can only offer a vague guess: it sounds as if there is a temperature sensor OR a control board failure.

On 2022-11-20 by Dan F

My Mr Steam turns on as it has for 5 years, but all of a sudden when I set the temperature it will begin creating steam and then randomly you hear various circuits click on and off, steam stops then it begins again but never reaches the heat set. I've had Mr Steams before and have never had this happen. Thoughts?

On 2022-08-16 by InspectApedia-911 (mod) - Gemini Aroma Spa two person Spa

@Cynthiahodges ,

Since yours is a packaged steam room set-up, I think that the steam controls and temperature sensor location and wiring are factory-set-up, right?

If so then we'd rule out putting a temperature sensor at a bad location (say right in the steam outlet path)

so what's left is a bad temperature sensor or, less likely, a loose electrical connector.

I'm not sure I can see the Spa brand and model: give us that so that together we can check the manual's troubleshooting suggestions before contacting the manufacturer.

@Cal,

It's normal for some water to drip from the steam head after the unit is shut down - for perhaps a minute or two as there may be steam therein cooling to condensate.

But if it continues beyond then there's probably a solenoid valve leak.

On 2021-12-23 by Inspectapedia Com Moderator - Diagnose & Clear an EE error code on some Steam Generators

@mike c,

Diagnose & Clear an EE error code on some Steam Generators:

What are the brand and model of your steam generator?

I ask because error codes are not universal across all steam generator brands and models.

But on the off chance we can GUESS usefully

Your steam generator may be receiving water at an excessive pressure. We've seen this EE error code reported for Happybuy Steam Generators (Amazon):

Check the water pressure being delivered to your unit to be sure it's not higher than is permitted by the IO manual or try reducing the supply pressure to 5 psi.
Then turn the unit off and drain pressure from the unit. Leave it off for a few minutes or longer. Then return power and water supply - at 5 psi.

Let me know if that works for you.

On 2021-12-23 by mike c

my control panel always has 1 or 2 EE's. it runs for about 10 minutes gets up to 115 degrees or so then shuts off.

In order to absolutely assure our readers that we write and report without bias we do not sell any products nor do we have any business or financial relationships that could create such conflicts of interest.

However you will certainly be able to find an onsite service technician who works on steam bath installation - that's what's needed. Or you might get help from a licensed electrician.

I suspect that the electrician or steam generator technician will first check the current draw of your steam bath heater, posing that perhaps the heater is malfunctioning and drawing too much current and so tripping the breaker.

She'll also check the control board and also the circuit breaker size against the wire size and the current draw required for the steam generator itself.

A savvy tech might also check the wiring connections (loose or corroded or burned) and also check for known problem-brands of circuit breakers and electrical panels.

Watch out: meanwhile LEAVE THE SYSTEM TURNED OFF at the electrical panel. That burning smell tells me there is a serious electrical problem; we don't want to risk a fire.

p.s. should someone like to connect with me privately u can do so via my email at leed2@msn.com

Hi, first time posting as I found the site hear a Google search and need help with diagnosing and fixing a 13 year old steam shower, Ariel WS-600 (their technician 13 years ago referred to it as a MGM 6000?) that is tripping the circuit breaker after anywhere from 25 to 50 minutes of being on.

Had not used steam function in years then last week tried it out. Initially the steam unit runs fine for anywhere from about 25-50 minutes but then it dies, perhaps overheating (tripping circuit).

Immediately before it dies pattern I have noticed is that a lot of steam comes into shower for final 20-40 seconds or so before it shuts down, and then there's a burnt smell.

Any help and/or advice you can offer is greatly appreciated! And, of course, my objective would be ideally to schedule time with someone who does service calls in Central New Jersey (I live in a small town next to Princeton) to come out to diagnose/repair.

Additionally, I contacted the manufactures distributor here in the US, Atlas/Arial (based in California) and via email they recommended pressing a “heat reset” button which given the location of the unit I am unable to access myself without removing the unit and I’m very reluctant to try doing so.

Moreover, would unit still be able to generate steam, that is after it shuts downs and I reset circuit breaker restoring electric power, even though I have not touched and depressed the heat reset button? Can you please explain what the heat reset button does and what happens after it is reset?

Any assistance and/or advice that can be provided by the members of this forum is greatly appreciated, thx!

On 2020-11-15 - by (mod) - signs of a bad steam room temprature sensor

That sounds like a bad sensor in the steam room, Byron. That is an integral part of the control - depending on model, wall-mounted or hand-held.

But before ordering a new control I'd check with Mr. Steam to be sure they don't want you to check cable connections at the circuit board or a relay on the board itself (a more expensive part by far)

Thanks for a helpful and interesting question about upgrading the controls on older Mr. Steam units. I've repeated it along with this reply now near the bottom of the article above.


I'm doubtful that you can replace your older Mr. Steam generator control by simply installing the new iTempo control without also changing the control board; the newer control and cable and connectors expect to plug into a connector on the newer control board for newer Mr. Steam units.

I'd want to ask Mr. Steam tech support first whether that's useful; the newer control board will have features that the newer controls operate but that may not have an actual counterpart or device to *be* controlled on the actual steam generator.

There are certainly some things to check before bailing out on this Mr. Steam generator.

If you don't have the manual, you can download it as a free PDF - links are above on this page in the section titled

Steam Generator Installation & Repair Manuals & Resources

You'll see troubleshooting steps both on this very web page as well as in the manual. Let's go through those before calling the manufacturer (whose contact info is also given above).

You need to assure that the steam generator has water and electrical power, then watch the 3 status lights as we describe above.

That's where I'd start.

Let me know what you see.

Thank you for your advice!

On 2020-05-30 - by (mod) - causes & cures of steam generator noise?

Carl

Thank you for asking a helpful question that I'd rephrase as

What steam generator noises are normal, which noises are abnormal, and what are the causes & cures of steam generator noise?

The Mr. Steam operation with which I'm familiar is very quiet, just a bit of gurgling as water enters the steam generator, and when the system is up to temperature, just a low pitched hiss as steam exits the supply port into the steam room.

Mr. Steam describes the normal steam exit noise as a gentle "whooshing sound" which is accurate in my view as well.

A third noise is a fairly quiet popping or crackling noise, not unlike the sound produced by some water heaters when there's a scale problem in the water heater base. In the steam generator this noise is normal and is not usually audible in the steam room unless the generator is mounted right against an uninsulated wood framed wall in common with the steam room.

Abnormal noises at any steam generator mean that some repair or maintenance or corrective action is needed. These include the following:

- Buzzing - usually an electrical problem such as a failing relay or transformer that we discuss in more detail at

HVAC NOISE-1 BANG BUZZ VIBRATE - banging, bearings, buzzing, thumping, vibrating sounds


On a Mr. Steam unit the other component that may buzz is the solenoid valve that opens or closes to admit water into the steam generator. You may be able to fix this noise by cleaning the strainer built-into the solenoid valve.

Note that a "click" noise may be noticed when the valve opens or closes - that's normal.

Mr. Steam says that if you're hearing a whistling noise then there's probably an improperly sized pipe used in the installation. Especially if the noise has always been present, I'd suspect this snafu.

Mr. Steam offers their own noise diagnosis article at

How to Prevent Steam Generator Noise https://blog.mrsteam.com/bid/318042/How-to-Prevent-Steam-Generator-Noise

High noise may be a piping problem or a temperature control problem or a partial blockage in the system.

If these tips don't sort out the Mr. Steam noise you're citing (you did not describe the type of sound) then you may want to give Mr. Steam a call for advice.

On 2020-05-30 by Carl

On 2020-01-11 - by (mod) - Mr Steam 2.0 controller not working

Dan

Before replacing the control board (pricey) or the controller/display (also pricey) I would

1. confirm that the power lights are on and normal at the steam generator

2. visually inspect the control board for signs of damage such as burn marks

3. check (plug and unplug) the control cable at the control board

4. this is more trouble but you might carefully pull the wall controller off and out to check the control cable connection there

5. Give Mr. Steam tech support a call. If the control cable or even just one of the wires in it is damaged your system will indeed refuse to work properly.

Worse, a short in the control cable can damage the control board, so you don't to install a new control board and then ruin it by a bad cable.

Let me know how you progress as that'll help others

Mr Steam 104232RD-PC control replacement cited & discussed at InspectApedia.comOn 2019-11-01 by (mod) - Inspect & test the steam generator control switch before replacing it

Hi Terry

In my experience the probability of a control failure would be in this order


1. an electrical wire connection at the switch or at the steam unit control circuit board

2. a failure in the control itself, perhaps from leaks or corrosion

3. damaged control wire between switch and steam generator


It's almost certain that Mr. Steam can sell you a new control switch; you might need to run new wiring too or change connectors on the old wiring. But before going to that expense you could try

1. Check the control wire connections at the control board in the steam generator


2. Carefully, with POWER OFF to the system, remove the switch and disassembling it to see if there is obvious damage to the switch or its connectors.

A replacement control switch such as the Mr Steam 104232RD-PC shown here retails for about $90. U.S. but before ordering a switch check with the manufacturer to be sure it is compatible with your steam generator model.

System Status Codes

The AirTempo may display a status code if the steam system is not functioning correctly.

CO indicates the AirTempo control has lost communication with the steam generator.

Ensure all connections are secure between the steam generator and the transceiver


Err P indicates an error while pairing, reset the control and redo pairing.

A complete list of steam generator status codes can be found in the MrSteam Residential Steambath Installation Operation and Maintenance Manual.

Pairing

AirTempos are factory paired, however if more than one steam system is installed in close proximity the AirTempo controls must be paired to their transceivers to prevent interference.

To pair AirTempo use a blunt object to press the button inside the transceiver adjacent to the LED. Hold the button for 5 seconds, when the transceiver is in pairing mode the LED will turn blink blue for 2 minutes.

While the transceiver LED is blinking, press and hold the button on AirTempo for 5 seconds until the display reads PAIR.

I have had a similar problem with the older iTempo controller and found that a worker had driven a screw through one of the controller wires.

We were able to fix the problem by replacing the control cable between controller and steam generator.

Watch out: a dead short between any of the AirTempo or iTempo control cable wires can damage the control circuitry inside the controller or worse, inside the Mr. Steam steam generator.
