Testing Dispenser
The dispenser wax motor is activated by 120 volts and
can be function tested outside the product with an
approved service cord.
With power applied to the wax motor, the actuator will
extend to release the detergent cover, this should
happen within 30 to 45 seconds. As power is removed
from the wax motor, the plunger in the wax motor
retracts. The pin at the opposite end now falls in the
rinse aid actuator. As it does, it follows a track down
the back side of the actuator to the bottom. The
dispenser is now ready to dispense the rinse aid. The
next time power is applied to the wax motor, rinse aid is
released into the tub.
To test the dispenser:
1. Attach a service cord to the wax motor.
2. Apply power and allow actuator to fully extend.
3. Disconnect power and allow actuator to completely
retract.
4. Repeat to actuate rinse aid dispenser.
Door Latch Assembly
The door latch and switch assembly holds the inner door
panel tight against the tub-door seal. The door switches,
mounted to the door latch, make sure all operation of the
dishwasher stops if the door is opened. The primary
purpose of the door latch and switch assembly is to
increase the safety for the user and to protect their
property. The door latch has two microswitches, one
mounted to each side of the latch. For safety, both sides
of the electrical power to the dishwasher will be broken
when the door is opened.

Cam Used To Actuate Door Switches
Open Position
Closed Position
When operating the dispenser with a
service cord, the wax motor will become
very hot when power is applied. This can
cause a burn if touched.
The wax motor runs on 120 VAC.
Make sure the service cord used in this
procedure is approved and in accordance with all local
and state electrical codes.
WARNING
As the door moves to the tub, the latch inside the console
pushes into a strike mounted to the top of the tub, which
pushes back a cam located inside the latch.
(See Figure 3-14)
This cam pushes against a spring that in turn, lowers an
actuator over the two normally open microswitches,
closing the switches and starting the dishwasher.
(See Figure 3-15) The latch and door switches are an
assembly and cannot be replaced separately.
To test the door switches:
1. Disconnect power to the unit for safety.
2. When checking a switch always remove one wire
from the switch.
3. Now check the switch for continuity with the latch
closed, then for no continuity with the switch open.
