Door lock control A31
This card serves to perform a safety check of the
door lock function.
The card checks the water level using level gu-
ard B2 and the drum speed by way of a rotation
sensor B3. The card receives a signal from the
CPU card when the door should be locked or
opened.
The door lock control controls the door lock coil
and the door lock does not open or close until
the card itself and the programme unit have veri-
fied that the drum is not turning and that there is
no water remaining in the drum.
The door lock control is described in detail in
section Door and door lock.
