On a Whirlpool dishwasher, a no-start complaint often comes down to a door that is not fully latched, Control Lock, a delay option, or loss of power.
Safety first: Unplug the appliance before touching accessible hoses, filters, or panels. Do not bypass a door or lid switch, probe live wiring, or continue using an appliance with smoke, a burning smell, sparking, a hot plug, repeated breaker trips, or water near electrical parts.
Most Likely Causes
1. Control Lock is selected
Whirlpool buttons differ by series, so avoid copied key combinations.
2. The start command was interrupted
The latch must close normally before a wash can begin.
3. The latch or strike is misaligned
Check safe external conditions first.
4. Delay Start is waiting
Whirlpool buttons differ by series, so avoid copied key combinations.
5. Power is missing
The latch must close normally before a wash can begin.
6. A console or control fault
Check safe external conditions first.
Step-by-Step Diagnosis
Step 1: Read the panel
Use the owner guide for the exact control panel.
Step 2: Cancel lock or delay
Do not bypass the door safety switch.
Step 3: Press Start and close door
Retry a basic cycle once.
Step 4: Check rack interference
Use the owner guide for the exact control panel.
Step 5: Check breaker
Do not bypass the door safety switch.
Step 6: Power-reset and retry
Retry a basic cycle once.
Components Related to This Symptom
A qualified technician may inspect the door latch, strike plate, console, control board, inlet valve, and junction-box supply. The symptom alone does not confirm a failed part.
When to Call a Professional
Book service if the safe checks do not solve the problem, a code or symptom returns, or the repair requires meter testing, internal wiring access, appliance removal, or disassembly. Stop immediately for burning odor, sparks, hot wiring, breaker trips, or water near electrical parts.

Frequently Asked Questions
Why does it start only when I hold the button?

Will breaker reset help?
It can clear a temporary control interruption but not repair a damaged part.
Bottom Line
