Pressure switch assembly
The pressure switch is located in the console.
It is made up of a knob and gear assembly that allows
the user to adjust the water level in the tub, an
adjustable pressure switch and plastic tubing that
connects the pressure switch to the outer tub. When
the tub does not have water in it, the air in the plastic
tubing is at atmospheric pressure and the spring in the
pressure switch holds contacts 1 to 2 closed, completing
the circuit to the water valves. As water enter the tub
the air in the tube is compressed. When pressure in
the tube exceeds the pressure of the spring in the
pressure switch, the contact of the pressure switch
change from 1 to 2 to 2 to 3 turning off the water
valves and suppling power to the motor circuit.
Wash cycle options switch (some models)
The wash cycle options cycle switch is located in the
console.
The wash cycle options feature allows the user to set
combinations of POWER SCRUB, REGULAR WASH
AND EXTRA RINSE cycles and have the cycles run
continuously. The contacts of the switch bypass the
OFF position between these cycles so the timer advances
from one cycle to another without stopping.
Wash/rinse temperature switch
The wash/rinse temperature switch is located in the
console.
The wash/rinse temperature switch allows the user to
select the water temperature in the wash and rinse
cycles. The switch controls the water temperature by
supplying power to the hot and cold solenoids of the
water valve, and in some models, the auto temperature
control.
The switch has 2 input terminals that receive power
from the timer. Two output terminals (on models without
the auto temp feature) are connected to the hot and
cold solenoids of the water valve. If the model has the
auto temp feature the switch has a third output terminal
supplying power to the auto temp control.
