Drain Valve - Electrolux WE170V Service Manual

Drain valve

The water pressure in the cold water intake is used for closing the drain valve. There is a hose (1)
connected between the water intake and the control valve (2). When the control valve is without power (un-
activated) it is open and lets the incoming water pressure into the supply line (3) to close the drain valve.
The water presses up a rubber membrane (4) and a plunger (5) with a pressure plate (6) which closes the
valve's rubber membrane (7).
When the control valve is powered (activated) the water pressure is released via the return hose (9). The
springs (8) pulls back the plunger together with the weight of the water and the drain valve is open.
