Water Valve Assembly

Cold Solenoid
Steam Solenoid
Hot Solenoid
Operating Voltage: 120 VAC
Resistance: 1 kΩ each valve
Location: See Water Valve Assembly Location on
page 35.
The steam valve part of the water valve assembly
is a low fl ow water valve used during steam cycles.
Steam is created by heating a small amount of
water in the sump.
The fl ow meter is built into the water valve assem-
bly and cannot be replaced separately. It is used to
monitor fi ll rate and keep a cumulative count of the
amount of water that has entered the washer. The
fl ow meter consists of a hall senor and water paddle
that has 2 embedded magnets. Water fl ow causes
the paddle to rotate. As the paddle rotates, the
magnets of the paddle interact with the hall senor
which generates a pulse train to the IMC board.
