The short answer
A dishwasher that does nothing at all is usually not broken in the way it looks. On the BDDIT 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
- 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.
- Some buttons respond and others do not — A failing membrane or touch panel, which is a part rather than a setting.
- 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 BDDIT line
- Door latch or interlock switch not made — Most likely here. 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.
- No power reaching the machine — Second on this family. Many installations put the dishwasher on a switched socket under the sink, and that switch gets knocked by everything stored around it.
- Starts but stalls with no water arriving — Third, and less common. It belongs on this list because of how the fault presents, not because of what it is.
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.
- Prove power at the machine, not at the wall — Check the breaker, then the switched spur or socket the machine is fed from — often inside the adjacent cupboard — and confirm it is on before assuming anything about the appliance.
- Confirm the supply valve under the sink is open — Start a cycle and listen for fill within the first minute. Silence where water should be running means the machine stalled rather than failed to start.
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
The line is simple on the BDDIT line: anything you can do with the door, the panel and the breaker is yours; anything that needs the toe panel off and a meter in hand is a service call. A breaker that trips immediately is the one case where you should stop entirely and call — that is a short, and repeated resets are the wrong thing to do to it.
