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.
To replace dispenser:
• shut off electricity to dishwasher,
• remove outer door panel assembly,
• disconnect wiring to the actuator,
• remove the six screws,
• remove the dispenser,
• replace and reinstall screws,
• rewire actuator.
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.This venting method eliminates
discharging heated moisture into the motor
compartment. The heated, moist air leaving the
dishwasher through the console vent causes

Personal Injury Hazard
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
with the timer set in the main wash.
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 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
hose, the drain pump connector hose, the wiring
harness connections made at the circulation
motor, the water heat thermostats 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 to 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
