Answer first
On a Wizard dishwasher, refusing to start usually comes down to the door latch and its switch, with the timer or control board 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
- The door latch and its switch — A machine that reads its door as open will not fill, and it will not tell you why. First on a mechanical machine: the latch physically closes the circuit, and decades of slamming leave it no longer making contact even though it feels shut.
- The timer or control board — It starts a cycle and never advances out of the first step, or does nothing at all. Second. The timer on a machine of this generation is a motor and a set of cams, and cams that have worn stop advancing out of the first step.
- No power at the outlet, the breaker or a switched socket — Third: worth two minutes before anything comes apart, and the only check here that needs no tools.
- A seized wash motor — Fourth, and the point where an old machine usually stops being repaired: it begins, draws hard, and drops out in the first minute.
Check in this order, and why that order
- 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. It goes first: top-ranked above, and free to rule out.
- Watch whether the machine starts and then stops in the first step — Starting and never advancing separates the control from the door and the power. Second: the next cause in the ranking, and this check separates it from the first.
- 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. Third, once both checks above come back clean.
What an owner can safely check
- 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
- Watch whether the machine starts and then stops in the first step — Starting and never advancing separates the control from the door and the power. Note what you find.
About 5 min
- 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
- 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 machine of this age, ask what the repair costs against what the machine is worth before agreeing to it, and ask whether the part can still be sourced.

What this page does not cover
This page is written for the Wizard 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.
