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 drier air to be drawn into the unit by 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.
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,
Tub and Door Seal
The door seal is pressed into the tub channel for an interference fit. Center the gasket (marked on back) at the tub top center and press in place
Power Dry Air Flow
The Power Dry configuration is the same as the Standard except it has a cross flow blower located in the air discharge path. The blower assists the heating element in producing power to drive the moist air out of the dishwasher.
• remove the six screws,
• remove the dispenser,
• replace and reinstall screws,
• rewire actuator.
To replace actuator:
• shut off electricity to dishwasher,
• disconnect wiring to the actuator,
• place a flat head screwdriver under the actuator body and between the dispenser housing and terminal side, twist and lift up on the actuator being careful not to damage the retainer snap-fits,
• replace with new actuator by pressing into place,
• rewire actuator.
without stretching or bunching. The gasket takes a short turn at the bottom of the tub channel before ending at the channel end wall.

Pump Assembly
The pump assembly is driven by a 1/12 HP, shaded pole motor. Rotation is in the counterclockwise direction at 3100 to 3200 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 entrance to the 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 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

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.
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, 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, the motor/impeller assembly can be 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 head screws from the volute cover. Using a large flat head screwdriver inserted between the impeller screw and the sump’s volute, the motor/ impeller assembly can be gently pried out of the sump. Use the screwdriver as a lever.
Voltage checks of the heater should be made in the dry portion of the service test mode.
