The short answer
On the DWS family a no-start divides cleanly into dead panel and lit panel. That split decides everything afterwards and it reorders the brand-generic diagnostic, which treats the two as one fault.
What you observe
- The machine beeps and cancels immediately — A door that closes but does not latch square gives exactly this.
- Cycle starts then stops within a minute — A fill or level fault rather than a start fault, though it presents the same way to the owner.
- No lights at all on the panel — A power question, not a machine question: breaker, cord or the switched supply under the sink.
- Panel lights but nothing happens on start — The control has power and is refusing to run, which usually means the latch is not making.
- NEAR MISS - it runs but nothing gets clean — That is a wash-flow fault and belongs on the cleaning page.
Causes, most likely first on DWS
- Control lock, delay start or a demo mode left on — Ranked first on the DWS family: a lock or a delay left set produces a machine that will not respond to start and has nothing wrong with it at all. That is a family-level property rather than a model-level one, which is why it leads here and not on a page about one machine. This moves above door latch or its switch not making, which leads the brand-generic order, because the family spans several sizes on one platform and it is the shared parts that wear.
- No power at the appliance — Second: a standard US household branch circuit is 15 A or 20 A at 120 V, and these machines share one with the disposer more often than they should.
- Door latch or its switch not making — Third: the control reads the latch, not the door, so a striker that has shifted by a millimetre leaves a machine that looks shut and behaves dead.
- Control board or user-interface failure — Fourth: last, and genuinely uncommon: most boards changed for this were reporting an interlock that was not making.
- Thermal or door-interlock protection tripped — Last: a protective device that has opened leaves the panel dead exactly as a supply fault does.
Check in this order, and why
- Confirm the panel lights at all — This one observation splits the fault in two and saves everything that follows.
- Open and close the door firmly and try again — If it starts on a firm close, the latch or striker is the fault and not the control.
- Confirm the stop tap is open before blaming the control — A machine that cannot fill abandons the cycle in a way that reads as a refusal to start.
- Rule out control lock and delay start — Hold the lock button for a few seconds and cancel any delay, then retry.
Before you open anything
Safety
Kill the power at the breaker and the water at the stop tap before anything comes apart, and leave the door interlock alone: it exists so the machine cannot spray with the door open.
When to call a technician
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The latch, the breaker and the panel modes are owner checks. Call when the supply is confirmed live, the latch makes and the machine still will not run.
