9.6 Door interlock

There are two types of door interlock:

• voltmetric with PTC: it is always necessary to wait from 1 to 3 minutes before opening the door.

• instantaneous: the door can be opened as soon as the cycle ends.

9.6.1 Voltmetric interlock with PTC

1. Suppressor

2. Main switch (button or

programme selector)

3. Door interlock

4. Main PCB

5. Door pilot lamp closed

• Operating principle

ª When the washing programme is started by pressing the START/PAUSE button, the bi-metal PTC

(contacts 3-5) is powered by the triac on the PCB (J10-2 connector): after 2 – 4 seconds, this closes the

switch (5-4) which powers the electrical components of the appliance (only if the door is closed).

ª The door interlock prevents aperture of the door while the appliance is in operation.

ª At the end of the washing programme, the PCB disconnects the interlock from the power supply, but the

door remains locked for 1 to 2 minutes (PTC cooling time).

Door locked” pilot lamp

ª Certain models feature a pilot lamp which lights to indicate that the door is locked. This pilot lamp

switches off when the door can be opened.
