Hotpoint dishwasher won't start, any ideas?

If it is completely dead with no lights at all, the fault is usually in the power supply, door switch area, wiring, or the main control board. You may be able to narrow it down yourself before calling anyone.

1. Check the obvious power supply first Make sure the plug, socket, and fuse are all OK. Try another appliance in the same socket, and if the dishwasher has a fused plug, check/replace the fuse with the correct rating.

2. Check for a tripped spur or RCD If it is hard-wired or fed from a switched fused spur, make sure that hasn’t tripped or been switched off. Also check your consumer unit for a tripped breaker or RCD.

3. Look for signs of life when the door is opened Open the door and see if there are any faint LEDs, beeps, or response at all from the control panel. If absolutely nothing, that points more towards loss of supply or an internal electrical fault.

4. Inspect the door area Is the door closing properly and latching firmly? A failed door interlock can stop operation, although total loss of all lights can also indicate a power/control issue rather than just the latch.

5. If you are competent, check internal connections Isolate the appliance from the mains first. Then check for burnt connections, damaged wiring where it passes into the door, or obvious signs of damage on the control board. Door wiring can fatigue with repeated opening and closing.

6. When to call an engineer If the supply to the machine is definitely present but it remains dead, it will likely need proper electrical testing of the wiring, on/off circuitry, door switch, or PCB.

Please isolate it from the mains before inspecting any internal parts, and use a qualified engineer for any mains electrical testing or repair. If you want, I can also talk you through the most likely checks in the safest order.
