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 discharge end of the drain pump. The drain hose

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 and rotating the four sump retainers toward the middle of the sump.

900 Watt Heater

cycle. The heater cycles ON and OFF for brief
periods during the drying cycle.

Standard Dry Air Flow

The heated, moist air leaves the dishwasher through the console vent causing 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,

•remove the six screws,

•remove the dispenser,

•replace and reinstall screws,

•rewire actuator.

Tub and Door Seal

The door seal is pressed into the tub channel for	without stretching or bunching. The gasket takes
an interference fit. Center the gasket (marked on	a short turn at the bottom of the tub channel
back) at the tub top center and press in place	before ending at the channel end wall.
