When closing the lid the door lock gets an impulse from the electronic by contact 3. The impulse feeds
the magnetic coil over the PTC resistor. This moves the lever down and the tooth lock washer is
forwarded by another tooth. This can be heard by a click. The locking part is unlocked, the lid is closed.
When opening the lid, e.g. with the start/pause button or at the end of the cycle, the door lock gets two
impulses from the electronic. The tooth lock washer is moved twice. Only because of the second impulse
the lid can be opened immediately.
The second impulse unlocks the locking part mechanically through the tooth lock washer.
Why two impulses?
The door lock is controlled by a triac which is on the main circuit board. If there is a triac short circuit, the
electronic sends an impulse to the door lock. The customer could open the appliance, if the second
impulse was not required.
If there is a power failure during a wash cycle, the door lock requires approx. 2 min until the lid can be
opened. During this time the PTC bimetal cools down and the locking part opens.
