With this valve, if cold is selected, only
the cold water solenoid is energized. If
hot is selected, only the hot water
solenoid is energized. If warm is
selected, both solenoids are energized
and the temperature is a mixture of
whatever the cold and hot water tem-
peratures provide. Also, the pressure
of the water is a factor since the cold
and hot water is mixed.
The next drawing shows a three
solenoid valve. When cold is selected,
only the cold water solenoid is ener-
gized. When warm or hot is selected
with an Energy Saver feature, both the
cold and the hot water solenoids are
energized. Plus, the Energy Saver
solenoid is also energized. This not
only allows water from the hot an cold
water sources but also provides some
water form the Energy Saver solenoid,
which is energized, and mixes an addi-
tional amount of cold water with the hot
and cold already being supplied. The
result is a colder warm and a cooler
hot.

The next drawing shows a two solenoid
water valve with a thermistor. This is
caused on the microprocessor model
(LAT9904). The thermistor checks the
temperature of the water and elec-
trically controls the temperature by
means of opening and closing the cold
and hot water solenoids to provide the
desired water temperature. Assuming
140°F. hot water and 60°F. cold water
are available with normal water pres-
sure.

If the washer won't fill properly, make
the following checks before replacing
the water valve.
• Check faucets to make sure they are
turned on.
