A clear filter does not establish that the whole drain system is unobstructed. Note whether water never leaves, drains slowly or returns after the cycle. Then check the accessible sink-side route before requesting a pump diagnosis.
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
“No blockage” often means only that no blockage was visible in the filter. Hidden routing, the sink connection and the way water returns remain unverified. Be precise about which areas were actually checked. That language helps a professional continue the diagnosis instead of treating an inaccessible hose as already cleared or replacing a pump because the most visible filter looked clean.
Start with the relevant branch
Check the shared sink drain
Record whether the sink drains slowly or the air gap overflows. These observations can point service toward the household side of the connection.
Record recent changes
A newly installed disposal, cabinet work or a moved hose is useful evidence. Ask the installer to verify connections rather than dismantling a built-in appliance.

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.
