The short answer first
Start at the machine correctly refusing to run with the door ajar: it explains more of these calls than anything else on a machine of this kind. Only when power, door and controls are all confirmed does a component become the suspect.
Symptoms, including the misleading ones
- The controls do not respond to any button — Check for a control lock, which is often a long press on one of the panel buttons.
- It starts, runs for a few seconds, then stops — Usually water: the machine waits for a fill it never gets and gives up.
- The door does not feel like it latches properly — A latch that clicks without engaging is the most common single cause of this complaint.
- NEAR MISS — it runs but leaves the dishes dirty — A machine that completes a cycle badly is a cleaning complaint, and that page ranks the causes for it.
The causes in order of likelihood
- The machine correctly refusing to run with the door ajar — Latches wear, doors drop on their hinges, and a rack pushed out slightly can hold the door off its catch. The result is a machine that starts sometimes and not others, which owners read as an electronic fault. It comes first for a practical reason: the check takes minutes and it decides which half of this list you need. The platform behind a smaller badge is usually a common contract build, so the causes that lead here are the generic ones that class is known for.
- No power at the machine — A breaker that has tripped will usually have tripped for a reason, but a one-off trip after a power cut or a surge is common and resetting it once is reasonable. A breaker that trips again immediately is a fault and needs an electrician. It ranks below the first only because the first is more common, not because it is harder to find.
- A cycle selected but never actually started — Panels have a child lock, a delay start and, on some machines, a showroom mode — all of which produce a machine that lights up and will not run. None of them is a fault, and all of them are cleared from the panel. Third in order, and the point where the checks start costing more time than they save.
- The interlock switch itself, electrically dead — When power is present, the door latches, the controls are unlocked and water is available, what is left is the electrical path: the door switch, the panel and the control board. That is a part and a meter, not a check. At the foot of the list, on likelihood alone.
Where to look, and in what order
- Push the door firmly closed while pressing start — If it runs, the latch or the door alignment is the fault, not the controls. Do this first: it settles the likeliest cause before any tool comes out.
- Check the consumer unit for a tripped breaker or RCD — Note whether anything else in the kitchen is dead at the same time. Second, and still no tools beyond a torch.
- Look for a padlock symbol or a delay indicator on the panel — Either explains the complaint completely, and the manual gives the key combination to clear it. Last of the owner-side checks; anything past it belongs to a technician.
What an owner can safely check
- Push the racks fully home and re-seat anything proud of the door line — Then close the door slowly and listen for the catch to engage.
About 10 min
- Switch the isolator and the appliance socket on, and try again — Do this before anything else; it resolves a large share of dead-panel complaints.
About 10 min
- Switch the machine off at the wall for a minute, then select a cycle from scratch — A clean restart clears a hung panel without any part being touched.
About 10 min
- STOP here and write down what each check showed — A technician arriving with the cheap causes already eliminated spends the visit fixing rather than repeating your work.
The part that is not optional
Safety
Before anything is opened, switch the appliance off at its isolator and let the tub cool — a machine that has just finished a cycle holds water hot enough to scald. Mop up standing water before you kneel in front of it.
When to call a technician
Call an electrician rather than an appliance technician if the breaker trips as soon as the machine is switched on, or if other sockets on the same circuit are dead. That is a wiring fault and it is not the dishwasher's to fix.
