with a large orifice and seat where the water can be
stopped. The outlet of the valve body empties into the
mixing chamber. A moveable rubber diaphragm oper-
ates 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
armature operates within a closed metal tube (valve
guide) which is sealed by the outer edge of the dia-
phragm to the valve body. A coil spring holds the
armature down against the diaphragm main orifice when
the solenoid is not energized.
The following line drawings and text explains basic
valve operation.
When the valve is in a closed position, the solenoid is
not energized. Water has bled through the diaphragm
bleed orifice placing incoming line pressure on top of the
diaphragm. The bottom of the diaphragm is essentially
at atmospheric pressure (open to the outlet) and the
pressure differential holds the valve shut.

When the solenoid is energized, the resulting magnetic
field pulls the armature up into the valve guide.

END OF CYCLE SIGNAL
When in the ON position, the cycle signal will sound
when the wash cycle is completed and the clothes are
ready to be removed for drying. The level of sound is
adjustable from LOW to HIGH.
To Remove or Replace End of Cycle Signal:
1. Same as replacement procedure for Water Tem-
perature Control Switch.
EXTRA RINSE SWITCH
The extra rinse switch provides an extra rinse in the
regular wash cycle when selected. This is accom-
plished by energizing the drain pump to remove the
water from the wash tub. When enough water is re-
moved from the tub that the pressure switch is no longer
satisfied, the pressure switch will reset and energize
the fill valve, thus creating an extra rinse.

perature Control Switch.
WATER INLET VALVE
The water inlet valve is actually two solenoid operated
valves in one body. A hot water inlet and a cold water
inlet valve discharge into a common mixing chamber.
The flow of water out of the chamber is controlled by a
rubber flow washer capable of maintaining a flow rate of
4.2 gallons per minute ± 10%, with incoming water
pressure of 20 to 120 P.S.I. The inlet valves are
controlled by the timer and water temperature selector
switch, individually or together, to provide hot, cold, or
warm water for washing and cold or warm water for
rinsing. The temperature of the warm mixture will be
dependent upon the temperature and pressure of the hot
and cold water supply lines.
Valve Operation
Both inlet solenoid valves are identical in construction
and operation. The valve body provides an air passage
