A dishwasher that won't start usually has a door-latch, power or control issue — check in that order.
Likely causes, ranked
- Door not fully latched or latch faulty Most likely — The cycle cannot start until the latch is detected.
- No power Likely — Check the socket with another appliance and the plug fuse.
- Delayed start active Likely — A delay timer may be counting down without being obvious.
- Control board fault Less likely — Dead panel with confirmed power points to the board.
First checks
- Check the socket with another appliance.
- Open and firmly reclose the door until it clicks.
- Press Start and listen for the latch engaging.
- Cancel any delay-start setting.
- Unplug for 1 minute, restore power, and retry.
Safety
Unplug before checking the plug fuse.
Call a professional when…
Call a professional if the panel is dead with confirmed power and a latched door — board or wiring fault.
