After the fill in the main wash, the control applies
power to the wax motor actuator. The plunger of the
wax motor extends pressing down on a pivot arm
attached to the latch for the cover, this releases the
cover to dispense the detergent. On the opposite
end of this pivot arm is a pin that rides up in the
actuating arm for the rinse aid dispenser. Once
power has been removed from the wax motor, the
plunger retracts the pin riding in the rinse aid actuator
follows a track down the back side of the actuator.
The dispenser is now ready to dispense the rinse
aid. The control again applies power to the wax
motor the pivot arm raises the rinse aid actuator to
release rinse aid into the dishwasher. When power
is removed from the wax motor the pivot arm falls
and a leaf spring mounted to the side on the dis-
penser forces the actuator arm to the starting
position for the next cycle.
Door latch assembly
The door latch assembly performs two functions: first
to close and latch the door to the tub, second is to
actuate both of the door safety switches to insure the
door is closed before the dishwasher can be oper-
ated. The latch mechanism is mounted to the inside
door panel with a lock tab at the bottom of the latch
body and two location pins on the back then secured
with two screws. As the door is closed the strike
mounted to the top of the tub presses in on the
locking cam and rotates it forward this raises a lock
into the center opening of the strike. As the cam in
the latch is pressed forward it releases the door
switch actuator closing both switches. See Figure 25
The handle mounted to the outer door panel is used
to open and close the door
Fill system
The fill system of this dishwasher consists of the
water fill valve and a float safety switch. Power from
the control is applied to the water fill valve through
the float safety. The water valve is an electrically
operated shut off valve with a flow washer that
regulates the amount of water based on the water
pressure applied to the valve inlet. Water pressure
needs to be between 20 and 120 psi for the dish-
washer to have the proper amount of water for
operation. See Figure 26
The float safety switch will shut off power to the valve
if the tub over fills with water. Water enters the tub
through an air gap mounted to the left side of the tub.
See Figure 27
Door Hinge and Spring
The inner door panel is attached to the tub frame by
hinges. On the face of both hinges there are fiber
pads that act as breaks to hold the door at any angle,
these pads do not interfere with the smooth up and
down movement of the door. There are door springs
and cables on both hinges to assist in opening and
closing the door. The door spring, which is attached
to the rear frame, has a cable that passes around a
friction bearing before attaching to the door hinge.
This spring and cable assembly provides a quieter,
smoother, operating door. See Figure 28
