Electrolux EWX11831 - Door Safety Interlock PTO

Technical Support - MDM 47/104 599 77 39-16 Rev. 00
11.7 Door safety interlock PTO (Pull To Open)
11.7.1 General characteristics
This appliance is not fitted with a safety device featuring the traditional fastening latch which necessitated the
removal of the handle to open the appliance door.
The new safety device uses a new hook version with a hole in the middle, shown by the arrow (see figure) and
you pull the handle to open the appliance door.
The instantaneous door interlock allows the door to be opened as soon as the drum stops, if the conditions
described hereafter are met.

 When the programme starts (start/pause button) the main circuit board sends a voltage pulse, lasting
20msec., to the solenoid valve (2) (at least 6 seconds should have passed since turning it on), which
moves the cam (4) to a locking position; the blocking pin (5) is pushed, locking the cursor (8), which moves
behind the ratchet (2) to prevent it from turning, locking the latch inside the lock (see subsequent figures);
simultaneously the main switch contacts are shut (6).
