Drain - Electrolux Evolution Service Manual

OPERATION
The motor is actioned in the drain direction in order to drain the water from the sump (17). At the same
time, a vacuum is generated in the IWMS level circuit and, via the level siphon (15), empties the pressure
chamber. As a result, the pressure switch (14) switches to "empty" (1 - 2).
If the anti-overflow device (2) is actioned via the siphon (16), this empties the corresponding pressure
chamber and thus disactivates the device.
N.B. It may occur that the anti-overflow device (2) is activated while the fill solenoid is in operation. In this
case, the anti-overflow device (2) has remained in operation while the pressure chamber is empty.
Therefore, in order to disactivate the device, it is necessary to bleed pressure from inside the
solenoid by disconnecting the fill hose connected to the tap.
