When a washer will not drain, the issue is often related to hose position, filter blockage, or a pump fault.
Safe checks before service
- Confirm the drain hose is not kinked or crushed behind the machine.
- Verify the standpipe height follows the manufacturer guidelines for your model.
- Clean accessible debris filters if your washer includes one.
- Run a short drain/spin cycle with a small load to observe behavior.
Likely causes
- Drain hose restriction
- Clogged pump filter
- Failing drain pump
- Lid lock or door lock signal issue
When to stop and call a pro
Stop if you smell burning, hear loud grinding from the pump area, or continue seeing standing water after safe checks. Professional diagnosis is the safest next step.
