The short answer
A dishwasher that does nothing at all is usually not broken in the way it looks. On the DWT line the door latch and the supply to the machine account for most no-start complaints, and both are checked without tools. A machine with a lit panel that refuses to run is a different fault from one that is completely dead, and the split is worth making first. The name covers a small group of numbers that share their construction, which is what fixes the order of the checks below.
What you observe on these models
- The start button beeps and nothing happens — The command was accepted and then abandoned, which usually points at the door interlock rather than at the button.
- A delay-start or lock indicator is lit — The machine is doing exactly what it was told. This is the single most common no-start that is not a fault at all.
- The door will not latch firmly, or has to be pressed hard — A latch that only just makes is a latch that intermittently does not, and the machine will not run without it.
- It starts, runs for a moment, then stops with the panel lit — The cycle began and stalled — usually no water — which the owner reads as a machine that will not start.
- NEAR MISS — it runs but the water never heats — That is a heating fault, not a starting fault, and it belongs on a different page.
Causes, most likely first on the DWT line
- Door latch or interlock switch not made — First, and the cheapest to rule out. The machine will not power the pump with the door believed open, so a worn latch reads to the control as a permanently open door.
- Control lock, delay start or demo mode active — Next most likely on these models. A delay start simply moves the cycle to later; the owner sees a machine that did nothing when the door was closed.
- Touch panel or membrane failed — Third — worth checking once the two above are clean. It is recognised by selective response rather than by no response at all.
Check in this order, and why
- Close the door deliberately and listen for the latch — It should click home with light pressure. If it needs a shove, or the door sits proud at one corner, the interlock is the suspect and nothing else needs testing yet.
- Look for a lock, delay or demo indicator on the panel — Hold the documented lock button for a few seconds to clear it. A delay-start that was set by accident explains a machine that did nothing for hours and then ran at night.
- Press every button in turn and note which respond — Selective response is a membrane fault. No response at all on a lit panel moves the suspicion back to the interlock or the board.
Before you open anything
Safety
Switch the machine off at its breaker before a panel comes off or a hand goes into the sump — a capacitor can hold a charge after the power is off. Shut the supply valve under the sink before disturbing a fitting, and never wedge the door interlock to watch a wash run.

When to call a technician
Owner work ends at the point where power has been proven at the machine and the door is latching properly. Past that, a dead panel means an open protective device, a failed board or a failed panel, and each of those needs testing rather than guessing. Do not order a control board on the strength of a dead panel — a thermal fuse produces the identical symptom for a fraction of the cost.
