Electronic Water Level Sensor; Water Inlet Valve; Valve Operation - Electrolux 6000 series Service Manual

Electronic Water Level Sensor:

The electronic water level sensor is mounted to the right
side panel under the top of the washer and controls the
water level in the washer.
The electronic water level sensor is made up of an
electronic board and a bellow inside a sealed chamber.
The chamber is connected by a hose to the air bell
located at the bottom of the washer attached to the drain
boot. The electronic board reads the pressure in the
bellow and converts it into an electronic signal. This signal
is then sent to the control board which governs the
incoming water by connecting or disconnecting a neutral
line to the water solenoids.
Water Inlet Valve Assembly:
The water inlet valve assembly is made up of a plastic
housing, 2 tubes, which the inlet water hoses are
connected to, 3 solenoids and a positive thermal sensor.
Hot
Wash
Bleach
The hot solenoid is connected to the incoming hot water.
The wash and bleach solenoids share a common input
cavity that is connected to the cold water supply.
The hot and wash solenoids share a common output
cavity, with the bleach solenoid having a separate output
cavity.

Valve Operation:

The (3) inlet solenoid valves are identical in construction
and operation. The valve body provides an air passage
with a large orifice and seat where the water can be
stopped. The outlet of the valve body empties into a
chamber. A moveable rubber diaphragm operates
against the valve seat to start and stop the flow of water.
The diaphragm is operated by water pressure. It has a
small bleed orifice outside the seat contact area, and a
large main orifice at its center. The armature of the
solenoid serves to open and close the main orifice. The
