Short answer
A washer that won't drain is usually blocked: a clogged pump filter (front-loaders), a kinked drain hose, a small item caught in the pump, or a slow household drain. These can be checked safely. If the drain path is clear and the pump hums without moving water — or makes no sound at all — the pump or its control likely needs a technician.
Before you open anything
Safety
- Unplug the washer.
- Front-loader filters release a lot of water: towels, a shallow pan, and patience.
- Never open a front-loader door with hot water inside.

Safe checks
- Straighten the drain hose; make sure it isn't pushed more than a few inches into the standpipe.
- Front-loaders: open the lower access panel and clean the pump filter per the manual.
- Check pockets-type debris: coins, hair ties, and socks are common culprits.
- Run a drain-and-spin cycle with a light load.
- If a nearby sink or floor drain is also slow, the clog may be in the house plumbing.
What the sound tells you
| During drain | Possible cause |
|---|---|
| Hum, no water moving | Pump blocked or seized |
| Silence | Pump motor, wiring, lid/door lock signal, or control |
| Drains slowly | Partial clog in filter, hose, or house drain |
Cost outlook
Clearing a blockage is the cheapest outcome. A drain pump replacement is a common, moderate repair. A control fault costs more and depends on parts availability.
Possible causes in more detail
| Cause | Typical clue | Who fixes it |
|---|---|---|
| Clogged pump filter | Front-loader, slow drain, debris visible behind the panel | You, per the manual |
| Object in the pump | Rattling or clicking during drain | Technician if it's past the filter |
| Kinked or crushed drain hose | Machine was recently moved | You |
| Household drain clog | Standpipe overflows or other drains are slow | Plumber |
| Failed drain pump | Hum or silence with a clear filter and hose | Technician |
| Lid/door lock or control fault | Error code, cycle stops before drain | Technician |

Common questions
Where is the filter on my washer?
Most front-loaders have a small panel at the bottom front. Many top-loaders have no user-cleanable filter. Your manual shows the location.
