Dishwasher Won’t Drain: Filter, Sink, and Hose Clues
Quick Answer
Substantial water after a completed drain can indicate a filter obstruction, drain-path problem, or pump fault. Inspect a user-removable filter according to the manual and note slow sink drainage. Small water residue in some filter wells can be normal. Do not use drain chemicals or reach into an unseen sump where glass may be present.
Is It Safe to Keep Using?
Avoid further normal operation with water near electricity, severe movement, excessive heat, gas odors, damaged surfaces, or recurring electrical faults. Resolve the symptom before routine use.
Check These Things First
- Confirm completion and use the manual’s drain command.
- Check only a user-removable filter.
- Note recent disposal or plumbing work.
Most Likely Causes
| Possible cause | Common symptom | Homeowner check | Professional repair often needed? |
|---|---|---|---|
| Filter debris | Water remains after drain | Clean per manual | Not usually |
| Drain-path issue | Sink backs up or recent work | Observe sink drainage | Plumber may be needed |
| Pump fault | Drain command repeatedly fails | Record sound and message | Yes |
What the Symptoms Can Tell You
A problem after disposal installation can involve the drain connection. Report that history before purchasing a pump. A slow sink and dishwasher can share a plumbing issue.
What You Can Check Yourself
Avoid hidden sharp objects. Do not disconnect hoses with water in the tub. Stop if water reaches electrical areas.
When to Stop Troubleshooting
Stop for smoke, burning smells, sparking, damaged wiring, repeated breaker trips, or water around electrical equipment. Never touch wet plugs. For fire or smoke, leave and contact emergency services. For gas odor, leave without operating switches and call the utility or emergency services from safety.
Do not open covers to access wiring, high-voltage components, gas parts, or refrigerant circuits. Never bypass fuses, safety switches, interlocks, grounding, or gas safety systems.
What Repair May Involve
Assessment can involve the household connection, hose routing, or pump. Plumbing and appliance faults need different services.
Repair Cost
Pricing depends on the confirmed fault, model, parts, labor, and access. Ask for an itemized estimate and whether a diagnostic charge is credited toward repair. The related cost guide explains comparisons without an invented national average.
Repair or Replace?
Compare repair history, age, parts availability, warranty, and full installed replacement cost. A small repair on a dependable appliance may make sense; repeat faults or substantial work deserve a replacement comparison. Age alone does not decide.
