900 Watt Heater
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.
is attached by a worm gear clamp to the discharge
end of the drain pump.
The drain hose must have a loop at a
minimum
height of 32 inches
in order to insure proper
drainage.
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.
Pump Assembly
The pump assembly is driven by a synchronous
motor. Rotation is in the counterclockwise
direction at 3600 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
discharge end of the drain pump. The drain hose
without stretching or bunching. The gasket takes
a short turn at the bottom of the tub channel
before ending at the channel end wall.

Detergent and Rinse Aid Dispenser
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.

Standard Dry Air Flow
When the control advances to the “dry” portion of
the cycle, a linear actuator retracts a valve, which
opens a vent path through the console into the
kitchen. The heated, moist air leaving the
dishwasher through the console vent causes
drier air to be drawn into the unit by way of intake
