Answer first
On a Willz dishwasher, refusing to start usually comes down to no power at the outlet, the breaker or a switched socket, with the door latch and its switch next. Establish whether the console is dead or merely idle, because that single observation cuts the list in half.
What you actually observe
- Nothing happens at all when start is pressed — No lights, no fill, no sound.
- It lights up, accepts the cycle and then does nothing — That is a different fault from a dead console, and it narrows the list at once.
- NEAR MISS — it runs a cycle and leaves the dishes dirty — That is a cleaning fault, not a starting fault, and it has its own page.
Causes, most likely first on this platform
- No power at the outlet, the breaker or a switched socket — Many machines share a switch with a disposal, and that switch gets turned off by accident. First, and it is right far more often than it has any right to be: many machines in this class share a switched socket with a disposal, and that switch gets turned off by accident.
- The door latch and its switch — A machine that reads its door as open will not fill, and it will not tell you why. Second. A simple latch and a microswitch are all that tells the machine its door is shut, and a latch that has gone soft reads as open.
- Control lock or a delay start left set — Third: control lock and delay start both look exactly like a dead machine, and both clear in seconds.
- The supply shutoff under the sink closed — Fourth, and the one that produces a machine that starts and then stalls rather than one that never lights up.
Check in this order, and why that order
- Check the breaker and any switch that serves the machine — Many machines share a switched socket with a disposal, and that switch gets turned off by accident. It goes first: top-ranked above, and free to rule out.
- Close the door firmly and listen for the latch — A machine that reads its door as open will not fill and will not say why. Second: the next cause in the ranking, and this check separates it from the first.
- Look for a lock or delay indicator on the console — Both look exactly like a dead machine and both clear in seconds. Third, once both checks above come back clean.
What an owner can safely check
- Check the breaker, and any wall switch near the sink that might serve the machine — Two minutes, no tools, and it is right more often than it ought to be.
About 5 min
- Close the door hard enough to hear the latch engage, then press start again — If it starts, the latch is marginal and it will do this again.
About 5 min
- Hold the control-lock button down for a few seconds and cancel any delay start — The panel usually shows a small padlock or a clock when either is set.
About 5 min
- STOP HERE if the next step needs the machine unplugged and a panel removed — Anything behind the outer panel of a machine holding water and mains wiring is a service call.
Before you take anything off
Safety
Unplug the machine or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off, and this machine holds water and mains wiring in one cabinet. Never defeat the door latch switch, and never reach into a sump or a drain pump that is still plugged in: broken glass goes through a rubber glove.
Where an owner check ends
Call once the power, the door and the lock have all been ruled out, because the next checks are on live terminals inside the cabinet. There is no hazard in waiting, unless the machine trips a breaker when you try it, in which case stop trying. On a cost-reduced platform the cheap repairs are worth doing and the expensive ones rarely are, so get the cause named before agreeing to anything.

What this page does not cover
This page is written for the Willz dishwasher as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is linked here, and it is the more specific answer. Not here: part numbers, wiring colours, torque figures, panel sequences and component ratings, which differ by family.
