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

periods during the drying cycle.
Voltage checks of the heater should be made in
the dry portion of the service test mode.

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,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 isthenrouted up thesideofthe
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.

Standard Dry Air Flow
Whenthecontroladvancestothe “dry” portion of
thecycle,alinearactuatorretractsavalve,which
opens a vent path through the console 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 theunitby 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.
