11.2  Door safety interlock 

There are two types of door interlock: 

•

 

volumetric with PTC 

•

 instantaneous 

 

11.2.1 

Volumetric 

interlock 

with 

PTC 

      

 
 
 
 

10 Anti-disturbance 

filter 

19  Door safety interlock 
20 PCB 
 
ON/OFF = Main switch (incorporated in the 

programme selector) 

 
 
 
 
 
 

11.2.1.1 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 (Door_TY) on the PCB: 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 the door from being opened 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 a further 1 to 3 minutes (PTC cooling time).
