Start at the latch
Open and close the door and listen to the latch engage. A latch that feels soft, that needs a second push, or that has to be lifted while closing is the most likely explanation for a machine that ignores the start control. Beyond that, the selector and the supply are the remaining candidates, and the control itself is last.
What the machine does
- The start control does nothing although lamps are lit — Control power is present and the machine is refusing to commit, which is the latch case.
- The cycle starts and stops within a minute — A door that registered briefly and then did not, which is the same fault in a different guise.
- The selector has to be moved past a position and back — A selector contact problem, and it is distinguished by being position-specific.
- No lamp lights at all — A supply question rather than a control one, and it belongs on the will-not-start page.
- The machine runs the whole cycle but leaves dishes dirty — A cleaning complaint, and neither the latch nor the console is involved.
Ranked for a simple console
- The door latch assembly or its switch — First, comfortably. It is the single most worked part on the front of the machine, it is consulted before every cycle, and its failure presents as a console that ignores you.
- The selector or programme control contacts — Second. Mechanical contacts wear at the settings used most, which is why the fault is usually specific to one or two positions.
- A sensed fill or drain condition stopping the cycle — Third. It stops a running machine rather than preventing a start, which separates it cleanly.
- The control itself — Last. On a machine with this little electronics there is simply not much to fail, and the three above cost nothing to check.
Feel the door first
- Close the door slowly and listen for the latch to reach its stop — It is the top cause and the check takes two seconds.
- Try the machine with the door held firmly closed — If it runs while held, the latch is confirmed and nothing else needs testing.
- Move the selector through every position and start from each — A fault confined to certain settings identifies the selector.
- Only then look at fill and drain — They stop a running cycle rather than preventing one, so they belong later in the sequence.
Owner checks
- Open and close the door several times and note how the latch feels — A firm, definite click is healthy. Soft, sticky or needing a lift is the finding.
About 5 min
- Press the door firmly closed and try to start the machine — Running while pressed and stopping when released points squarely at the latch.
About 5 min
- Push both racks fully in and check nothing is holding the door proud — A handle or a tall item stops the latch reaching its position and mimics a failure exactly.
About 5 min
- Select each programme in turn and attempt a start from each one — Position-specific failures identify the selector without any tools at all.
About 10 min
- STOP before the inner door panel is opened — The latch switch and the console wiring sit behind it in a wet door, and that is the boundary.
Before anything is opened
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. On a hardwired dishwasher the breaker is the only isolation there is. Leave the door latch and its switch exactly as the factory fitted them, because the machine uses them to confirm the door is shut before it fills with hot water.
Where to hand over
Call once the latch has been felt, the racks are clear and the machine still refuses, because the latch switch and the selector both sit behind the door panel. Call the same day for any burning smell at the console or any discolouration at a pad. A latch assembly and a selector are both inexpensive, defined parts on a machine of this design, so the repair is usually straightforward.

Scope
Written for the Hotpoint dishwasher class rather than one model line. Latch part references, selector layouts and door panel fixings differ by family and belong on the page for your specific machine. Where that page exists it is the more precise answer; this one works from how the door feels.
