Washing machine leak repairs: this article describes both oil and water leak causes at washing machines. We discuss where oil may be coming from if it shows up on clothes after washing or on the floor under or around the washing machine. The article describes typical repairs at washing machine drums, baskets, and transmissions.

Here we also warn about building flooding and mold contamination that can result if a washer hose bursts while no one is at home. Links are included to related appliance diagnostic and repair procedures.

How to Diagnose & Repair Washing Machine Oil or Grease Leaks

Reader Question Pete said: [1/29/2014, originally posted at x]

My ejector pump went out and the basin was filled with oily water. Why? Where did that oil come from? The broken pump? which I replaced. Could my washing machine water which drains into the basin, have oil in it? Could that mean my washing machine is about to break down? Where did that oil come from?

I'm guessing that the pump motor failed and you are seeing pump lubricants in the basin. Certainly a washing machine motor and transmission also contain oil.

We've seen oil inside the cabinet or even on the floor beneath a failed washing machine. But how oil from components that are below the washer tub (the tub bearing, pump or transmission) enters the washer tub and from there would be pumped to a drain is more interesting.

A bad seal on a top loading or front loading washing machine tub may allow bearing lubricant into the washing water. I've seen this show up as surprising new black or dark brown stains on clothes that have ploveed through a wash cycle. A washing machine "hub and seal kit" can often repair this problem that may also show up as squeaks and squeals when the washer is running.

Conversely, I think that most transmission oil leaks (from a washing machine) drip to the space below the appliance. On some washer transmissions such as Whirlpool, there are two transmission seals, a top transmission cover seal and an input shaft seal - both of which can be replaced.

At below left we show a different washing machine leak problem: water leak stains on the under-side of subflooring beneath a washing machine that was leaking from a supply hose. At below right is an example of a sewage ejector pump where one might detect oil or grease from a leaky washing machine.

Some washing machine transmissions have a fitting through which transmission oil can be added, but doing so without fixing the transmission oil leak would be pointless IMHO. Replacing an entire washing machine transmission is possible (I've done it in the past) but the cost can be about half the cost of a new machine.

If you are not a do-it-yourself'er (or maybe even if you are) you may still be able to diagnose this problem far enough to decide whether or not to call an appliance repair person.

Look at the floor beneath your washing machine, look inside the washing machine body at the upper surface of its bottom floor (more trouble), and look in the washer as well as on clothes that went through the washer for signs of oil or grease stains.

Since we're talking about your sewage ejector pump basin (photo above), keep in mind that any oil source in the building would end up there. But the washing machine is a good start.

Keep us posted.

Risk of Costly Building Water Damage or Mold Contamination from Washing Machine Leaks

Watch out: for leaky or worn washing machine hoses connected to the water supply. Leaving home without turning off water supply to the washer can mean you return to a flooded building if one of these hoses bursts. Our moldy drywall (and clump of clothes dryer lint) at above left was caused by a small leak at a washing machine.

Our second photo (above left) shows a burst washing machine hose. This washer hose broke open when the building owners were out of town. The un-attended home was flooded and suffered extensive and expensive mold contamination discovered a week later when the homeowners returned.

Clothes Dryer Fire Hazard Warning

Watch out: as well while you are checking your clothes washing system, take a look at your DRYER VENTING instllation too: you want to be sure that system is safe as well.

A leaky washer transmission may stain clothes or leak onto the floor but an unsafe clothes dryer vent can set the building on fire.
