The short answer for AVDWEH models
On the AVDWEH line the commonest reason a machine will not start is the door not latching fully. The latch has to make a switch before anything else happens, and a rack pushed slightly proud or a seal that has swollen is enough to stop it.
Symptoms, and the ones that mean something else
- The control lock indicator is lit — The machine is behaving exactly as designed and ignoring every press.
- The cycle light comes on but no water enters — It has started and is waiting for a fill that is not happening.
- The panel is completely dead — No power reaching the machine, or its own supply has failed.
- It stops immediately after starting — It began and aborted, which is a different fault from never starting.
- NEAR MISS — it starts and then stops with water in the bottom — That is a drain fault and belongs on the drainage page.
Causes on AVDWEH, most likely first
- Door not latching fully — Ranked first because the latch operates a switch that gates everything else, and a rack pushed proud is enough to stop it making.
- Delay start set unintentionally — A flat touch panel makes this easy, and the machine is simply waiting.
- Water supply valve closed — Many machines start the cycle and then stall waiting for a fill that cannot happen.
- Control panel membrane failing — Some buttons respond and others do not, which is the tell.
Check in this order, and why
- Start with what the ranking makes most likely — On AVDWEH models, three of the four causes above are checkable without a panel coming off, and this order puts every one of them before anything that is not.
- Look at the panel before pressing anything — Dead, lit, locked or counting down are four different faults and the panel tells you which for free.
- Note whether it works from cold and fails later — That pattern points at a thermal cut-out rather than at a switch.
- Check the supply valve under the sink is open — A machine that starts and stalls is often waiting for water nobody turned back on.
Two isolations and one wait
Safety
Pull the plug or switch the breaker off, close the supply valve, and then wait for the machine to cool. A capacitor can hold a charge after the power is off, and the sump element of a dishwasher stays hot long after the cycle ends. Wear a glove when clearing the sump: glass fragments end up there and cannot be seen in water.

When to call a technician
The boundary on this machine is the base panel and the sump cover. Filters, spray arms, seals, hoses, loading and detergent are all yours. Anything that needs the machine out and a panel off is a service call, and so is any fault that has tripped a breaker.
