Water Valve
The water valve is a 120 VAC, double solenoid type,
which is accessed by placing the control panel in the
service position.
The water valve wiring is equipped with snubbers, on
each water valve connector, to reduce EMI. A shorted
snubber may cause a failure to occur on the electronic
control board (see Electronic Control Board).
Automatic Temperature Control (ATC)
The automatic temperature control feature is used to
provide optimum wash water temperature. The ATC
uses a water temperature sensor (thermistor) with a
negative temperature coefficient (as temperature rises,
resistance lowers), located in the top of the hose and
water inlet to detect incoming water temperature. The
electronic control board uses the difference between
the voltage sent to the water temperature sensor and
voltage returning from the water temperature sensor to
determine the temperature of the incoming water, and
to make (ATC) decisions.
The ATC should maintain the water temperature in the
tub within the ranges specified in the Water
Temperatures chart by opening or closing the hot and
cold water valves.
To prevent sudden water temperature changes on
consumer's hands, the ATC does not function when
the lid is open during warm or cold fill.
Note:
•
The ATC will flush the water inlets with hot water for
the first 6 seconds of a warm wash cycle.
•
During cold water fill, the hot water valve will open if
the water inlet temperature is too cold.
