Safety Lock
The machine can not be started until the door is closed (point ( B ) in the diagram does not receive voltage until the door is closed, see sequence diagram "Power supply and start"). When the start button on the machine is pressed, or the correct number of coins are inserted into the coin meter, the timer advances to stage 1. Row 9b (1) then closes and the solenoid which locks the door (4) receives voltage.
When the lock piston has locked the door, S4 (7) closes and point C receives voltage. It is only then that the drum can begin to revolve and water begin to fill.
At program stage 1, row 11b (3) closes up which means that the bimetal spring in the delay unit heats up. Once the spring is heated, the delay unit holds the door locked.
Row 11b is closed during the entire wash program. In the case of a power failure, it takes > 2 minutes for the
