Quick answer
Check power, that the door is firmly closed, and that child lock or delay start isn’t on. On many built-in dishwashers you select the programme, press Start, then close the door within seconds. If it persists with codes like LC, bE or AE, it needs checking.
Overview
Before starting, the dishwasher checks the door is closed and there’s no leak in the base — and on some models that water is available. If any check fails, it won’t start.
Always start with simple external causes before suspecting an internal fault.
Likely causes
-
1
No power
A tripped breaker or socket, or a built-in unit’s plug disconnected behind the cabinet.
-
2
Door not latched
A plate or rack prevents full closure, or the latch is damaged.

3
Child lock or delay start
Child lock disables buttons; delay start makes it wait for the set time.
-
4
Start method on built-in models
Many top-control dishwashers require closing the door right after pressing Start.
-
5
Leak sensor
Water in the base blocks starting and shows LC.

Button or main board
A stuck button (bE), a communication fault (AE) or a board power-supply fault.

Safe checks before calling a technician
Unplug the dishwasher before any check, and close its tap if there is a leak. Wear gloves when checking the sump in case of broken glass, and don’t open the side or bottom panels.
- Check the breaker and socket; try another appliance in the socket if possible.
- Make sure nothing blocks the door and close it firmly until it clicks.
- Turn off child lock and delay start per your manual.
- Select the programme, press Start, then close the door within seconds (built-in models).
- Unplug for 10 minutes, then restart.
Parts involved
Door latch & switch
Confirms to the board that the door is closed; without it the programme won’t start.
Display & button board
The interface where you choose programmes and see time and error codes.
Main control board
Runs the programmes and drives pumps, valve and heater based on sensor readings.
Leak sensor (float)
A float in the base pan that rises when water collects, stopping filling, running the drain pump and showing a leak code.
Wiring & connectors
Link components to the board; moisture or rubbing can cause breaks or shorts.
When should you call a technician?
- No response at all despite power.

Frequently asked questions
Why does it beep and not start?
Usually the door wasn’t closed within the allowed time after pressing Start, or isn’t fully latched.
How do I turn off child lock?
It varies by model — usually a long press on one or two buttons for a few seconds, as your manual explains.
Will it start with the door open?
No — a firm close is essential for safety and to keep water in.
