Understanding the Problem
When a washer doesn't pump water out, it will often stop partway through the cycle, leave water in the tub, or display a drain-related error code. This can be caused by a mechanical failure in the drain pump itself, an electrical fault (lid/door switch or control board), or a simple clog in the drain hose, pump filter, or trap. The washer may make a humming or grinding noise when the pump tries to run but fails to move water. Diagnosing the issue starts with simple visual and audible checks: run a drain/spin cycle and listen for the pump motor, inspect and clear the drain hose and pump filter of debris, and watch for error codes. If the pump is blocked, cleaning usually fixes it. If the pump motor doesn't run, hums, or has no continuity, replacing the drain pump (or related components like the lid/door switch or belt on older models) is commonly required.
Common Symptoms
Water remains in the drum after the cycle, washer stops mid-cycle, drain/spin doesn't run, humming or grinding noises from the base, or drain-related error codes.
Common Causes
- Failed or seized drain pump motor (electrical or mechanical failure)
- Clogged drain hose, pump filter, or pump impeller blocked by debris
- Faulty lid/door switch, pressure/float switch, or control board preventing the pump from receiving power

Helpful Repair Tip
Run a drain/spin cycle while listening at the washer for the pump motor. If you hear a hum but no water moves, check the pump trap and hose for foreign objects — then test pump continuity with a multimeter to confirm a bad pump.
Frequently Asked Questions
How can I tell if the drain pump is bad?
Signs of a bad pump include no sound when the washer tries to drain, a loud grinding or squealing noise, or the pump humming without moving water. First check and clear any visible clogs in the filter or hose. If the pump still won't run, unplug the washer and test the pump motor for continuity with a multimeter. No continuity or an open circuit indicates the pump motor needs replacement.
Can I clean or replace the pump myself and how much does it cost?
Yes — many homeowners can clean the pump filter or replace a drain pump. Always unplug the washer and shut off water before starting. Cleaning a filter/hose takes 10–30 minutes; replacing a pump typically takes 30–90 minutes depending on access. Parts cost: pump assemblies commonly range $40–$200 depending on brand; labor (if you hire a technician) varies. Always buy the correct part for your washer model and follow a model-specific guide.
