The short answer
On an ADC washer, a machine that will not start usually comes down to one thing before any of the expensive ones: the door lock or the interlock switch. The point where an owner check ends is marked in the steps.
What you observe
- No lights and no response to any button — The supply, not the machine, is the place to start.
- Lights come on and start does nothing — The machine has power and is refusing to run, which is a different list entirely.
- A click at the door and no cycle — The lock is attempting to engage and not confirming.
- NEAR MISS — the whole room has no power — Check the consumer unit first; the machine is probably fine.
- Body: Check these across more than one cycle and, where you can, against a neighbouring machine on the same supply: on a shared installation the pattern across machines is worth more than any single observation.
Causes, most likely first on ADC
- The door lock or the interlock switch — No washer will run without the door proven shut. Ranked first on ADC.
- An installation withholding permission — A machine installed for shared use often will not begin without its service valves open, its supply proven and whatever the installation requires satisfied. Second.
- Power is not reaching the machine — A tripped breaker, an outlet behind the machine that has worked loose, or a switched spur turned off. Third.
- The control board or the timer — The most expensive place to guess. Last, and that is the point of the order.
- Body: Is your machine bolted down and shared between households or shifts?
Check in this order, and why
- Turn the empty drum by hand — First: A drum that will not turn freely explains a hum with no movement, and it takes one hand and no tools.
- Close the door firmly and listen for the lock — Second: It is free, and the lock is the commonest single cause.
- Check the breaker, the outlet and any switched spur — Third: A machine with no lights has already told you the fault is upstream of it.
What an owner can safely check
- Push the door firmly shut and press start again — A door that needs an extra push to latch is a lock diagnosis, and this takes seconds.
About 5 min
- Check the breaker and the outlet, and reset once — Reset a tripped breaker once.
About 10 min
- Cancel any programme in progress and drain the machine — Use the cancel or the drain-and-spin programme and let it clear before selecting anything new.
About 20 min
- STOP HERE before testing the lock, the motor or the board — All three are live-terminal tests behind a panel.
Before you open anything
Safety
Isolate at the breaker and close both valves before a panel or a hose is touched: the capacitor holds a charge past the switch, and the drum and sump hold more water than they look like they do. The door interlock stays as it is — it is what keeps a fast-spinning drum shut, and it holds the door while the water is still hot.
When to call a technician
Call when the door latches firmly, the breaker and the outlet are live, no lock or delay is set, the water is on, the drum turns freely and the machine still will not begin — that puts it at the lock, the motor or the board. Call rather than retry if the breaker trips the moment you reset it, or if there is a smell of hot insulation at the machine. On a shared installation, report the fault with the schedule attached — which machine, at what time of day, and whether anything else was running.
