The short answer
On the Black Decker BDW dishwasher a machine that will not begin a cycle is usually power or water that is not arriving rather than a machine that has failed. The BDW list is a ladder of sizes on one mechanism, so the checks below hold across the model list in the table. Settle one thing first: is the panel dead, or is it alive and refusing?
What you observe
- No lights, no sound, nothing at all — Supply side: outlet, plug, breaker or the cord itself.
- The panel lights but the cycle never begins — The machine is alive and is refusing.
- It starts, runs briefly and stops again — Something is failing a check part-way in — most often fill, which the machine times and abandons quietly.
- NEAR MISS — it runs but leaves the dishes dirty — That is a cleaning fault rather than a start fault, and the cleaning page is the one that will help.
Causes, most likely first on the BDW family
- The outlet, plug, cord and breaker — First on this family — the BDW list is a ladder of sizes on one mechanism — and these machines are frequently plugged into a sink-side outlet shared with other appliances and protected by a device that can trip without anyone noticing. A dead panel is a supply fault until proven otherwise.
- Water supply, tap and coupler — Second: a machine with power but no water starts, times its fill, and gives up. Owners see a cycle that will not run, which is why this sits so high.
- Door latch and its switch — Third — still a common cause, and the first thing to check once the panel is proven alive.
- Control lock, delay and the control board — Last: the lock and delay are free to clear, and a genuine board failure is the rarest outcome on this list by a wide margin.
Check in this order, and why
- Plug something else into the same outlet — First and fastest: it proves or clears the top cause without any assumption, and a tripped protective device is easy to miss.
- Check the breaker and any protective device at the outlet — Second, because a device that trips only under load explains a machine that dies mid-cycle as well as one that never starts.
- Open the tap fully and confirm the coupler is seated — Third: it explains the version of this fault where the machine starts and then quietly abandons.
- Now work the door latch and look for a lock symbol — Last, with supply proven, so that a refusal means a refusal.
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. A machine that trips its protection repeatedly is telling you something, and it must not simply be reset over and over while you investigate.

When to call a technician
Call when power at the outlet is proven, the water is on, the door latches firmly and the panel still will not accept a programme — that is a latch switch or a control and it needs the door or the console opened. Call immediately if the machine trips a breaker or a protective device when it starts: repeated resets on a tripping circuit are not a diagnosis.
