• remove the six screws,
• remove the dispenser,
• replace and reinstall screws,
• rewire actuator.

• shut off electricity to dishwasher,
• disconnect wiring to the actuator,
• place a flat head screwdriver under the actuator

body and between the dispenser housing and
terminal side, twist and lift up on the actuator
being careful not to damage the retainer
snap-fits,

• replace with new actuator by pressing into

place,

• rewire actuator.

When the control  advances to the “dry” portion
of the cycle, a linear actuator retracts a vent valve
opening a vent path through a console vent into
the kitchen. This venting method eliminates
discharging heated moisture into the motor
compartment. The heated, moist air leaving the
dishwasher through the console vent causes
drier air to be drawn into the unit by way of intake
vents located at the bottom of the door. The
water on the dishes is evaporated into drier air
and the venting process continues. The heating
element is turned ON and OFF during the entire
drying cycle.

The Power Dry configuration is the same as the
Standard except it has a cross flow blower located
in the air discharge path. The blower assists the
heating element in producing power to drive the
moist air out of the dishwasher.

Refer to the cycle chart on the reverse side to
determine when the heater is on during the wash
cycle. The heater cycles ON and OFF for brief
periods during the drying cycle.

Voltage checks of the heater should be made in
the dry portion of the service test mode.

air lock. The drain loop on the side of the tub must
be kept in place after servicing.

The main pump can easily be removed by
disconnecting the upper spray arm supply tube,
the drain pump connector hose, and the wiring
harness connections made at the circulation
motor and the water heat thermistor located on
the bottom of the pump.

Once the pump assembly is removed from the
dishwasher, the motor/impeller assembly can be
removed from the sump by taking out the three
(3) T-20 Torx head screws from the aluminum
motor bracket and then the three (3) T-20 Torx
head screws from the volute cover. Using a large
flat head screwdriver inserted between the
impeller screw and the sump’s volute, the motor/
impeller assembly can be gently pried out of the
sump. Use the screwdriver as a lever.

The pump assembly is driven by a

 HP,

shaded pole motor. Rotation is in the
counterclockwise direction at 3100 to 3200 RPM.
The motor drives a pump which supplies 100
percent filtered water at a rate of approximately
12 GPM to one spray arm at a time. The spray
arm’s operation is alternated by small “pauses”
of the motor during the wash cycle.

Draining is accomplished by using a small
separate synchronous drain pump mounted to
the side of the sump. The drain pump is connected
to the main pump by a small rubber hose. The
drain check valve is located at the entrance to the
drain pump. The drain hose is attached by a
worm gear clamp to the discharge of the drain
pump. The drain is then routed up the side of the
dishwasher and attached to the side of the tub.
This drain loop insures that an air pocket cannot
form near the drain pump and cause the pump to

without stretching or bunching. The gasket takes
a short turn at the bottom of the tub channel
before ending at the channel end wall.

The detergent and rinse aid dispenser is a one
piece component consisting of a molded
detergent cup and a built-in rinse aid dispenser.

The detergent cup has a spring loaded cover and
the rinse aid dispenser has a removable cover.

Liquid rinse aid is added to the dispenser up to
the fill line indicator. The amount of rinse aid
released can be adjusted by turning the arrow
indicator from one, being the least amount, to
four, being the greatest amount.
