Start with the symptom

Dishwasher troubleshooting by symptom

Dishwasher problems are easier to narrow down when you identify when the symptom occurs: before filling, during washing, while draining, or after drying. Standing water, poor cleaning, and detergent residue can be related, but they do not always share the same cause.

Begin with loading, owner-removable filters, visible hoses, the sink connection, and the cycle settings. Do not open electrical, pump, or water-valve compartments unless the manufacturer lists the work as owner maintenance.

Common questions

What does standing water in a dishwasher mean?

Water covering the visible tub floor can point to a filter, drain hose, sink, disposal, or internal drain problem. A small amount below the filter may be normal on some models.

Why are dishes dirty even when the cycle finishes?

Loading, blocked spray movement, a dirty filter, detergent, water conditions, or a circulation or heating issue can all affect results.

Should I use chemical drain cleaner in a dishwasher?

No, unless the appliance manufacturer explicitly directs it. Caustic drain products can damage parts and create unsafe fumes or splashing.
