First distinguish water that never drains from water that appears again later. Whirlpool’s drain guidance includes the filter, hose and shared sink-side route. The timing helps direct a useful inspection without assuming every standing-water complaint needs a new pump.
Brand-level navigation and symptom classification. Exact-model pages own their documented controls and access procedures.
Stop and isolate power before permitted user maintenance, and let water cool. Watch for sharp debris. Do not reach blindly into a sump, open electrical panels or use drain-opening chemicals. Stay clear of water near electrical equipment.
Choose the observed outcome
Immediate standing water, slow drainage and water returning later are different observations. Keep that timing with the sink-side findings. A clean filter cannot verify backflow behavior or every hidden connection. If the symptom began with plumbing work, have that connection checked; if the route is confirmed correct, the technician can focus on the appliance rather than starting from a generic pump assumption.
Start with the relevant branch
Check shared drainage
If the sink drains slowly or the air gap overflows, record it. Have a plumbing restriction assessed; never use chemical drain opener inside the dishwasher.
Use the model’s filter procedure
With power isolated and water cool, clean only user-removable filtration described in the manual. Do not reach blindly into areas with possible broken glass.
First-cycle failure and air-gap overflow
If the appliance never drained after installation, ask the installer to verify the disposal connection and routing. Air-gap overflow directs attention to the downstream route; do not cap it or use drain-opening chemicals inside the dishwasher.
Go to the exact problem
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
