The short answer
A White-Westinghouse that will not start points first at a door latch that is not fully engaging. Work out whether the panel lights at all before anything else: that single fact halves the list. Nothing here needs the machine pulled out until the last cause.
What you actually observe
- It beeps when you press start and then stops — A refusal with a reason: the machine is telling you something is not ready.
- The panel is completely dark and nothing responds — No power reaching the machine, or an internal fuse has gone.
- NEAR MISS: it runs a full cycle but cleans nothing — Read the cleaning page instead.
The ranking: most likely cause first
- A door latch that is not fully engaging — The machine will not run unless the latch tells it the door is shut. A latch that has worn, a door that has dropped, or a rack sticking out by a finger's width, all stop the cycle before it begins. First, and the whole order below follows from it: it is a mechanical part operated several times a day and it is the single most common reason a dishwasher refuses to start.
- Control lock, child lock or delay start set — A key symbol on the panel, or a delay set by a child pressing buttons, leaves a machine that lights up, accepts nothing and looks broken. Next, and for a closely related reason: it is free to rule out and it is the answer far more often than anyone expects on a machine with a touch panel.
- No power reaching the machine — A tripped breaker, a switched spur behind a cupboard, or a plug in a socket under the sink that has been knocked. Third: a dishwasher is usually fed from a switch nobody can see, which is why this is checked early and not assumed.
- A failed door switch or thermal fuse — The switch behind the latch and the thermal fuse on the board are both safety interruptions in the circuit. Last on purpose: it needs the door panel off and a meter, which is where owner work stops.
The order to check in
- Close the door firmly and listen for the latch to click home — If it starts only when pushed hard, you have found it.
- Look for a lock symbol or a delay indicator on the display — Both are easy to set by accident and easy to clear.
- Check the breaker, and find the switch or socket that feeds the machine — A dark panel means power. A lit panel means it is not power.
The checks you can make yourself
- Push the racks fully in, close the door firmly and listen for a positive click — Check nothing, including a tall handle, is holding the door off its catch.
About 5 min
- Hold the lock button for a few seconds to clear a control lock, then cancel any delay start — Then try a cycle from a fresh start.
About 5 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Safety first, and it is not boilerplate
Safety
Switch the dishwasher off at its breaker or unplug it before removing any panel, and never take the inner door panel off with the machine live: the door switch circuit is mains voltage. A standard household branch circuit is fifteen or twenty amps at one hundred and twenty volts, so a dishwasher that trips its breaker is telling you something real. Never wedge or tape a door latch to make a machine run.
When to call a technician
Call once the latch clicks home, the power is confirmed at the switch, the controls are unlocked and the supply is open, because what is left is behind the door panel or on the board. Call immediately if the machine trips its breaker or smells hot.

What is deliberately not on this page
This page covers the White-Westinghouse dishwasher as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: switch part numbers, fuse ratings, board pinouts and any door panel removal sequence, all of which differ by family and belong on the page for that family.
