Maytag lists door closure, supply availability and an obstructed overfill float among checks for a dishwasher that will not fill. A humming or running sound does not prove water is entering. Confirm the actual symptom before a valve or 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
A machine that has not actually begun the cycle can appear to “run without filling” when only a display or delay is active. Confirm that state before judging water entry. Once a true no-fill attempt is established, door closure, accessible supply and model-permitted float checks are separate branches. A running sound cannot establish that the inlet valve is receiving water or operating correctly.
Start with the relevant branch
Close the door normally
Check for an item preventing normal latching. Do not slam the door, bypass a switch or force an interlock to start the appliance.
Inspect only accessible user checks
Check the known water supply and any float inspection specifically described by the manual. Do not pull the built-in appliance or probe an electrical float switch.
Go to the exact problem
Use the observations above with the exact owner’s manual; no model-specific procedure is assumed.
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.
