Dishwasher leaving water: normal sump or drainage problem?
Water pooled across the tub after a completed cycle differs from moisture deep in the filter area. Document where water remains before assuming a pump failure.
What you may notice
- Water covers the bottom after a completed cycle.
- A sink backup or recent disposal installation coincides with the problem.
Common causes
Filter or drain restriction
Food accumulation or an external hose restriction may impede draining.
Installation or service issue
A connection problem, pump fault or other interruption may require a technician.
Step-by-step checklist
Confirm the cycle finished
Read the display and consult the model’s description of normal retained water.
Check the owner-serviceable filter
With the machine stopped and safely disconnected as instructed, clean only a removable filter the manual identifies. Beware of sharp debris.
Observe nearby plumbing
Note a slow sink, new disposal or visible hose kink. Leave disconnection and pump access to a professional.
When to stop and get help
- Stop for leaking water near electricity.
- Do not add drain-opening chemicals or reach blindly into the sump.
Prepare for a technician
- Record water depth/location, timing, displayed codes and recent plumbing changes.
Repair or replace?
- Ask whether the quote concerns household plumbing, installation or appliance components.
Compare itemized quotes or compare repair and replacement costs with your own figures.
Common questions
Can every filter be removed?
Follow the exact model manual.
