Door open conditions
Before pulses are sent to open the door, the PCB checks for the following conditions:
• the drum must be stationary (no signal from the tachometric generator).
• 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.
− Automatic release device
In the event of a power failure, turn the appliance off at the ON/OFF button,
solenoid fault, the bi-metal PTC cools in between 55 seconds and about 4 minutes
(with temperature of 65°C) and therefore releases the door.
− Solenoid protection
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 10 times)
