Electrolux EWX11831 Service Manual page 59

The second pulse (which is only sent if everything is in working order) moves the cam (4) to another
-
position, which causes the pin (5) to return to its position and therefore release the interlock; the
contacts of the main switch are simultaneously opened.
 Protection Solenoid
A PTC is connected in series to the solenoid to limit the current (and therefore any overheating) in the following
cases:
 Main circuit board TRIAC short circuit
 Many consecutive pressings of the start/pause button (more than 5 times)
Door open conditions
Before pulses are sent to release the door, the PCB checks for the following conditions:

The drum must be stationary.

The water level must not be higher than the lower edge of the door.

The temperature of the water must not be higher than 40°C.
 Manual release device
The previous door safety devices opened the door automatically, in the event of: power failure or the appliance
being turned off with the ON/OFF button (before the wash cycle ended) or valve malfunction or faulty main
board, because inside they had a PTC bi-metal which allowed the door to be opened after cooling, between
55 seconds and 4 minutes.
The new device has a manual opening system, which allows the door to be opened following the instructions
below:
Before activating the manual opening of the door, check:

If the water is above the lower level of the door, drain off the water; if possible set a drainage programme
(or using the filter drainage knob after unplugging it from the mains socket).
 Unplug the appliance from the socket.
 Check that the drum is stationary.
 Activate the manual opening system (see next paragraph).

If the water is not above the lower level of the door, then it can be opened manually.
Manual opening
Do the following:
1) Open the filter flap (lower right hand side) and inside there is a small rod indicated by the arrow Fig. 1.
2) Insert a flat-tip screwdriver into the slit see Fig. 2 and push the small rod downwards and
simultaneously activate the handle Fig. 3 and open the door.
