Standardexceptithasacrossflowblowerlocated
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.

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
causethepump to airlock.The drain loop onthe
sideofthetubmustbekeptinplaceafterservicing.
The main pump can easily be removed by
disconnecting the upper spray arm supply tube
hose,the drain pump connector hose,the wiring
harness connections made at the circulation
motor, the water heat thermistor located on the
bottom of the pump and rotating the four sump
retainers toward the middle of the sump.
PumpAssembly
The pump assembly is driven by a synchronous
motor. Rotation is in the counterclockwise
directionat3600RPM. The motor drives apump
which supplies 100 percent filtered water at a
rate of approximately 12 GPM to one spray arm
atatime.Thespray arm’soperationisalternated
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
withoutstretchingorbunching.Thegaskettakes
a short turn at the bottom of the tub channel
before ending at the channel end wall.

DetergentandRinseAidDispenser
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

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.

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 theunitbyway 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.
