Instructions for repair
To replace the door lock

Release the door lock by unscrewing the two
screws.
•
Pull out the lock mechanism. Transfer the
electrical connections one by one from the old

Insert the new unit and secure it with the
screws. Close the door and check carefully that
the lock will hold the door shut properly.

after the program has ended.
To replace the door status switch
To be carried out by authorised
personnel only.
•
Remove the front panel.
•
Undo the four screws for the hinges and
remove the door.
•
Unscrew the two screws holding the door lock
and take off the mounting plate.
•
Remove the trim panel as follows:
-
The trim panel is fixed to the outer drum by
six plastic rivets. Each of these rivets was
originally fixed by a wedge tapped into place
at its centre, causing it to expand.
-
Use a suitable tool to tap these wedges, to
release each one from its rivet. This will
allow you to remove the trim panel.
•
Unscrew the door status switch and replace the
microswitch, or possibly the entire switch unit.
•
Install the switch unit and fix the trim panel
back in place. New wedges for the rivets are
supplied in the spare parts kit for the door
status switch.
•
Refit the door lock and door.
•
Check the door status switch functions with the
aid of the service program (see Chapter 12,
Fault-finding).
