The short answer
An ADB dishwasher that will not start is usually being told not to rather than failing: split the complaint first: a dark panel and a lit panel that will not start are two different faults. Only the last cause on the list is a part. The order below puts no power reaching the machine first and the control board or the touch panel last, and that order is the point of the page.
What the owner actually sees
- The panel lights but nothing ever happens — The cycle is accepted and then nothing follows, with no fill and no pump.
- Completely dark panel, no response at all — Nothing lights anywhere, which is a supply question before it is an appliance question.
- It starts if the door is pressed while closed — The clearest evidence there is that the latch or the alignment is the fault.
- A lock indicator that nobody set deliberately — Control locks survive power cuts and are easy to trigger while cleaning the panel.
- NEAR MISS - it starts and stops partway through — A cycle that begins and abandons is a different fault; note the stage it stops at, because that is what a technician needs.
What it usually turns out to be, in order
- No power reaching the machine — Ranked first on this line: a tripped breaker, a switched spur turned off or a loose connection at the outlet leaves the machine completely dead. A standard household branch circuit is fifteen or twenty amps at one hundred and twenty volts, and a dishwasher usually shares one with little else.
- The door latch not making — Next, and close behind: this is first because it explains the exact complaint - a machine that accepts a cycle and never starts it - and because it is confirmed by closing the door differently.
- A control lock or a delay left set — Then: a child lock, a control lock or a delayed start will hold a machine silent with every light behaving normally. It is a setting, not a fault, and it cannot be repaired.
- The control board or the touch panel — Last, and the reason the order matters: a machine whose buttons work intermittently, or only in one corner of the panel, is usually the membrane rather than the board behind it.
Working order, and the reason for it
- Establish whether the panel is alive at all — Look at whether any indicator lights at all. A completely dark panel is a supply question; a lit panel that will not start is a latch, a lock or a supply-of-water question.
- Close the door deliberately and listen for the latch — Check nothing in the racks is proud of the frame and stopping the door from closing fully.
- Read the panel for a lock or a delay — Look for a lock indicator and for a delay setting, and clear both before anything else. Many machines hold the lock through a power cut.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Do not bypass the door latch or bridge a switch to make the machine run - that interlock stops a hot spray reaching an open room.
Where owner work ends
Call when the supply is proven, the lock is cleared, the door latches properly and the machine still does nothing. Call immediately, and leave it isolated, if there is any smell of overheating or the breaker trips when it is reset.
