Safety locking device

The machine safety locking device includes a safety interlock system which prevents

personal injury through the following precautions:

• The machine cannot be started until the door is shut.

• The door is automatically locked when the machine starts.

• It is not possible to open the door until 2-3 minutes have elapsed after the washing

program has ended. This ensures that the drum is motionless when the door is

opened.

The machine door lock is made up of the following main components:

• Lock unit, located behind the front panel under the detergent compartment. The unit

contains a coil which locks the door, and two microswitches. Switch S3 indicates that

the door is locked and switch S4 that the coil is activated.

• Delay unit, located inside the automatic control unit. This unit consists of a circuit

board which controls the time that the door remains locked in a power cut.

• Locking arm which connects the door handle with the lock unit. The arm relays the

mechanical action of the door handle to the lock unit.
