• replace and reinstall screws,
• rewire actuator.
To replace actuator:
• shut off electricity to dishwasher,
• disconnect wiring to the actuator,
• placeaflatheadscrewdriverundertheactuator
body and between the dispenser housing and
terminal side, twist and lift up on the actuator

Standard Dry Air Flow
When the control advances to the “dry” portion
ofthecycle,alinearactuatorretractsaventvalve
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
drierairto be drawn into theunit byway ofintake
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.
Power Dry Air Flow
The Power Dry configuration is the same as the
Standardexceptithasacrossflowblowerlocated
in the air discharge path. The blower assists the
heating element in producing power to drive the
moist air out of the dishwasher.

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,themotor/impellerassembly canbe
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
headscrewsfromthevolutecover.Using a large
flat head screwdriver inserted between the
impellerscrewandthe sump’s volute, the motor/
impeller assembly can be gently pried out of the
sump. Use the screwdriver as a lever.
Pump Assembly
The pump assembly is driven by a 1/12 HP,
shaded pole motor. Rotation is in the
counterclockwisedirectionat3100to3200RPM.
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
thesideofthesump.Thedrainpumpisconnected
to the main pump by a small rubber hose. The
draincheckvalveislocatedattheentrancetothe
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 theside of the
dishwasher and attached to the side of the tub.
This drain loop insures that an air pocket cannot

a short turn at the bottom of the tub channel
before ending at the channel end wall.

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.
To replace dispenser:
• shut off electricity to dishwasher,
• remove outer door panel assembly,
• disconnect wiring to the actuator,
