Troubleshooting guide

Washer Not Draining? Start With the Pump Filter

Water left in the drum is usually a sock, a coin or lint in the pump filter, or a kinked hose. Here is how to check safely, and how to tell when the pump has failed.

Short answer. Most front-load washers that won’t drain have something in the pump filter (coin trap) behind a small door at the bottom front: socks, coins, hair ties, lint. Clean it, then check the drain hose behind the machine for kinks and the standpipe for a clog. If the path is clear and the pump hums or stays silent, the drain pump has usually failed. A washer that won’t spin can also be a lid or door lock problem rather than a drain one.

Before you start

  • Don’t force the door of a front-loader that is full of water; the lock is holding it for a reason.
  • Have towels and a shallow pan ready. Opening the pump filter releases all the water left in the drum, and it comes out slowly through the small drain tube or all at once around the filter.
  • Leaking? Turn off the hot and cold supply valves behind the machine until it has been checked.

The checks, in order

  1. Pump filter or coin trap (most front-loaders and many compact washers): open the small panel at the bottom front, drain the water into the pan with the little hose if there is one, then unscrew the filter and clear it.
  2. Drain hose: pull the washer out enough to see the hose. A kink where it was pushed against the wall is common, especially in closets.
  3. Standpipe or sink: if the hose drains into a standpipe or laundry sink that backs up, the clog is in the house drain.
  4. Run a drain or spin cycle and listen.

Stacked and closet installations

Stacked washer-dryers and compact European washers often need the dryer lifted off or the unit pulled from a closet before anything can be tested. We bring floor protection and plan for it rather than discovering it on arrival, so tell us when you book. In San Francisco, where stacked units in hall closets are common, that planning is most of the job.

Repair or replace?

A pump, lock, boot seal, suspension or agitator coupling is a routine repair. A failed tub bearing on an inexpensive top-loader, or a control board on a machine already near the end of its life, often is not worth it, and we will say so. One customer called about a ten-year-old top-loader and was advised on the phone not to book a visit at all, because the repair would not pay off.

Common questions

How do I drain a washer full of water?
On most front-loaders, open the small panel at the bottom front and drain through the pump filter or its little hose into a shallow pan, with towels down. Don’t force the door while it is full.
Why won’t my washer drain after cleaning the filter?
Check the drain hose for kinks and the standpipe for a clog. If the path is clear and the pump hums or is silent, the pump or its power has failed.
My washer drains but won’t spin. Is it the same problem?
Not necessarily. Lid and door locks, unbalanced-load detection, the drive motor and on LG washers the rotor, stator or hall sensor can all stop a spin with a working drain.
Do you repair stacked washer-dryers in closets?
Yes. Tell us when you call so we plan for unstacking and bring the right equipment.
