My front loader is not starting and the E40 error is coming up?

It is a lid lock issue.

..

Family error code E40 is visible to customers and (could be E41,E42,E43,E44 and E45 only visible in service mode) means problem with open door or door interlock.
I suggest rapid reading alarm code when appliance is in normal operating mode (e.g. during the execution of the washing
programme):
Press and hold down START/PAUSE and any of the option buttons for at least two seconds: the LEDs initially switch off, and then display the flashing sequence corresponding to the alarm.
The alarm sequence continues as long as the two buttons are held down.
E41 - Door open
E42 - Problems of door closure
E43 - Interlock power supply triac faulty
E44 - Door interlock sensor faulty
E45 - Door interlock sensing circuit triac faulty

Possible causes:
Door interlock faulty, wiring faulty or PCB faulty.

I don't have an electrolux, but I have an LG front loader. Mine was giving a simular error code, and I found the drain hose filter was clogged. Bee running fine since

hi we just bought a second hand defy front loader washing maching can you please assist us how to use ot its Defy Daw 365 please

E40: Door open, Interlock, wiring or main PCB most likley going to be faulty door interlock.

Turn the power off, unplug the machine and take the top off your machine and on the front right of the machine there is a plastic case with lots of wires.

Put the wires out one block at a time, keep putting them in and out, this will help the connection to seat.

Try the machine again and the problem should be solved.

If not you may need a new board.

E40 is an error from the door locking mech (interlock).this is the bit behind the port hole door frame ,where the door striker pin goes through hole.hope this helps you.held on with 2 screws and you need to remove plastic clamp from door gasket to gain access.
E40.door not locking.door interlock faulty or triac faulty on pcb
hope this helps pls do let me know

hi there e40 fault is a problem with your door interlock. get it replaced and all will be fine..

hi there e40 fault could either be your door interlock or main pcb

e40 fault code is water level too low during heat which is very strange to appear at start-up. does anything else happen? without being certain, points to a main module fault
