Function
When the door is closed, the door status switch closes a circuit and sends
a signal to the program control unit to indicate that the machine is ready to
start.
When a program has been selected and the start button has been pressed,
the door lock will be activated and will lock the door, at the same as the
switch in the door status switch closes. Only now will the program control
unit allow the program to start.
When the door lock is activated a bimetallic component in the lock heats
up. If the power supply is interrupted, it takes about 1.5 minutes before the
bimetal cools enough to release the door lock. This gives enough time for
the drum to stop rotating and any water in the drum to be discharged (the
discharge valve will open automatically if the power supply is cut).
If a fault or error relating to the door locking system should arise, the
machine will stop and an error code will appear on the display (a flashing
two-digit code followed by E). These are the error codes which involve the
door lock:
Error code Cause
02E
Door status switch open during program operation.
03E
The lock has not locked the door within the set time.
17E
Door status switch open, even though the door lock is locked.
To trace the cause of faults which initiate any of these codes, refer to
Trouble-shooting.
