The short answer
A DWDI dishwasher that does nothing when you press start is usually a door-latch or power-supply problem rather than a failed control board. On this family the latch is the interlock the control listens to, so it comes before the board in the order, which is where this page departs from the brand-generic one.
What you observe
- 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.
- 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.
- 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 DWDI
- Door latch or its switch not making — Ranked first on the DWDI family: the latch on this family carries the interlock the control reads, so a worn striker reads as a dead machine. 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. What moves against the brand-generic order is lower down: control lock, delay start or a demo mode left on sits above thermal or door-interlock protection tripped here, because this family is a single build with fixed access points.
- 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.
- Control lock, delay start or a demo mode left on — Third: easy to miss on a panel where the lock indicator is small, and it costs nothing to rule out.
- Thermal or door-interlock protection tripped — Fourth: a protective device that has opened leaves the panel dead exactly as a supply fault does.
- Control board or user-interface failure — Last: last, and genuinely uncommon: most boards blamed for this were reporting a latch that was not making.
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
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Isolate the water at the stop tap as well as the power, and leave the door latch to do its job: judge a running cycle from outside the machine, with the door shut.
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.
