11.8 Door safety interlock

The door delay safety device ensures that while the tumble-dryer is working normally, it is impossible to open the door
for safety reasons and ensures that at the end of the wash cycle the door can only be opened after a set time.

lever
After pressing the START / PAUSE key a pre-established current passes through the bimetallic PTC (1) which
becoming misshapen causes the lock lever (2) to move, stopping the nib lock runner from moving.
At the end of the programme when the power supply to the bimetallic PTC (1) is disconnected a certain amount of
time is needed to allow it, previously misshapen, to return to its initial rest position thus unlocking the nib lock runner.
