Quick answer
A dishwasher that is not working needs a quick split between no power, a control state that blocks start, a door or water-supply condition, and a cycle that starts but stops or leaves water. Check the breaker or plug, control lock or sleep mode, door latch, water tap and selected cycle in that order. Whirlpool’s guidance supports one safe reset and model-manual checks; persistent leaks, trips, or no-start after these checks need service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Check whether the panel or indicators light, then inspect the plug or accessible supply and breaker once. Look for a hot, damaged or wet connection from outside.
Expected result: The panel is dark; the breaker is tripped; or the panel has power but ignores start.
Next step: Correct one safe accessible supply issue. Stop for damage or a repeat trip and arrange electrical or appliance service.
Why this matters
Why: A supply issue is more likely when the panel is dark. Power with ignored commands shifts toward control lock, sleep mode, door state or a fault.
-
Check 2
Open and close the door gently, confirm it latches, and make sure a rack or dish is not blocking the door path.
Expected result: The door was not latched; a load blocked closure; or the door latches but the cycle still will not begin.
Next step: Clear only the obstruction and make one start attempt. Do not bypass or hold the latch.
Why this matters
Why: A door signal or loading obstruction can prevent start. A latched door with no response needs another branch.
-
Check 3
Look for a control-lock, sleep, delay or flashing Start/Resume indication and use only the model manual’s method to clear it.
Expected result: A lock, sleep, delay or flashing start state is shown; or no control state is visible.
Next step: Clear the documented state once, select one normal cycle and press start once.
Why this matters
Why: A control or delayed-start state can make a working dishwasher appear inactive. Unknown controls require the exact manual, not a copied button hold.
-
Check 4
Confirm the accessible water supply tap is open and the inlet area has no obvious kink or leak, then observe one supervised start for fill, wash sound and drainage.
Expected result: The tap is off; the machine fills and runs; it stays silent; or water leaks or remains after the cycle.
Next step: Correct only a clearly closed tap or visible hose routing issue allowed by the installation. Arrange service for silence, leak or persistent drainage failure.
Why this matters
Why: Water supply can stall a cycle. A running but non-cleaning or non-draining machine is a different symptom from no start; a leak is a stop condition.

-
PATH 01Next step
What you see
The dishwasher is dark and the accessible supply is abnormal, with no water or electrical hazard.
Do this next
Correct the supply or call an electrician if the protection will not hold.
Why this path and its safety boundary
Why it matters: An installation power condition is more likely.
-
PATH 02Next step
What you see
The panel responds after a documented lock, sleep, door or cycle correction and the dishwasher completes a supervised start.
Do this next
Use the manual’s normal start sequence and monitor one cycle.
Why this path and its safety boundary
Why it matters: A control or setup state is more likely than a failed internal part.
-
PATH 03Next step
What you see
The door latches, the control state is normal, supply is accessible and normal, and one start attempt still leaves the dishwasher silent or leaking.
Do this next
Stop owner troubleshooting and arrange qualified service.
Why this path and its safety boundary
Why it matters: A door-interlock, inlet, control, pump or other internal fault remains possible without identifying one part.
Helpful context
Understand the symptom
“Not working” may mean the panel is dark, buttons respond but no cycle begins, the machine fills and stops, or water remains after a cycle. Note the exact pattern so a start problem is not confused with drainage or leakage.
Controls vary by model. Use the rating-plate model and manual before applying a lock sequence or reset combination.
When checks do not resolve it
Need a professional?
Provide the exact model and a concise record of what happened, which controls or indicators responded, and which safe checks changed the symptom.
Common questions
FAQ
How do I reset a dishwasher that will not start?
Use the model instructions; Whirlpool describes unplugging or switching off the breaker for one minute for many models, while some use Start/Reset.
Why does a dishwasher have power but not run?
Check control lock or sleep mode, door latch, selected cycle and water supply before one documented start attempt.
