Electronic Water Level Sensor; Water Inlet Valve - Electrolux GOOD Service Manual

Electronic Water Level Sensor (Better
Models)
The electronic water level sensor, mounted to the right
side panel under the top of the washer, controls the water
level in the washer.
The electronic water level sensor is made up of a
electronic board and a bellow inside a sealed chamber.
The chamber is connected by a hose to the air bell
attached to the drain boot located at the bottom of the
washer. The electronic board reads the pressure in the
bellow and converts it to an electronic signal. This signal
is sent to the control board. The control board controls
the incoming water by connecting or disconnecting
neutral to the water solenoids.
Water Inlet Valve Assembly
The water inlet valve assembly is made up of a plastic
housing, 2 tubes (that the inlet water hoses are con-
nected to), 3 solenoids and an automatic temperature
control (on better models only).
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
