The short answer
A DW machine that does nothing is far more often unlatched, locked out or unpowered than broken. A built-in is fed from a switch behind a cupboard, so power is harder to confirm here than on any other kind of dishwasher. Four of the five checks below take a minute each and need no tools at all. The 7 numbers in the table below share the construction this ranking is built on.
What you observe on these models
- The panel lights but nothing happens when you press start — The latch has not made, or a lock is set.
- It beeps but will not run — It is reporting something.
- No lights at all — Supply first, and on a built-in that means the switch behind the cupboard.
- It has power but will not begin a cycle — That splits the list in half: the supply is fine, so look at the latch and the lock.
- NEAR MISS — it runs but never fills — Read the supply and coupler checks rather than the power ones.
Causes, most likely first on the DW family
- The door latch not making — First on this platform: no latch, no cycle, and no error either.
- A delay start, a control lock or a cycle already in progress — Second: all three present as a dead machine and all three clear from the panel in seconds.
- A child lock held on the panel — Third: it is designed to make the machine ignore every button, which is indistinguishable from a dead control unless you know the symbol.
- A residual-current device tripped elsewhere — Fourth: kitchen circuits trip as a group, so a dead dishwasher is sometimes a tripped circuit with a fault in another appliance entirely.
- A delay timer set by accident — Last: one press while cleaning the panel puts a machine hours away from starting, and it looks exactly like a fault.
Check in this order, and why that order
- Open the door and close it firmly, listening for the latch — A rack standing proud is enough to stop it making, and there is no error to tell you.
- Look at the panel for a lock symbol, a delay or a cycle already running — Seconds to check, and it explains a dead machine surprisingly often.
- Check the tap is on and the coupler is seated — A portable that cannot fill often waits rather than runs.
- Look for a control lock or delay on the panel — Both look exactly like a dead machine.
- Try the socket with something else — A countertop machine shares a busy kitchen circuit and this is the commonest cause.
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. Isolating at the breaker is better than pulling the plug where the socket is behind the appliance, because it removes the temptation to work one-handed.

When to call a technician
Latches, locks, sockets, taps and supply valves are all owner checks on a built-in dishwasher, and together they explain most dead machines. On these models the line falls at the pump and the electrical components below the tub. Call without working through anything at all for a burning smell, a tripped breaker, or water reaching a socket.
