Washing machine wont start get E40 come up - Zanussi FJD1666W Front Load Washer

This is normally due to the door lock failing.
If you remove the clamp holding the door seal on the front.
Then peel the seal back and remove the 2 screws holding the door lock on.

You can change the lock from there and hopefully this will sort the problem out.
However if still doing the same after changing the lock then the control board will be faulty. But 9 times out of 10 for this fault its the door lock thats the problem
