the washing cycle. When the cycle is finished unlocking is done automatically by a programmer.
The lock has been blocked also during the failure situations e.g. electric network black out, before and after
the machine installation and you can unlock it in case of emergency according to the procedure hereafter
described.
LOCK WITHOUT TENSION BEFORE THE PROGRAM START
It is possible to open and shut the washing machine door any time. The lock will not be blocked, coils with the latch
are not active.

DOOR SHUTTING
The lock is secured by a blocking latch after the door is shut and the program has been started.
