Standard Dry Air Flow

When the control advances to the “dry” portion of the cycle, a vent actuation solenoid is closed. This opens the vent valve and starts the vent fan both located in the top right rear corner of the tub. The fan draws in the air from outside the tub, forcing the hot, humid air down and out the

bottom of the outer door panel. This outside, cooler, dryer air helps to speed evaporation of water from the hot dishes. At the same time the heating element is continually cycled on and off. On some models the dry portion of the cycle can be extended to improve drying performance.

Tub and Door Seal

The door seal is pressed into the tub channel for an interference fit. To install the seal, locate the center mark on the seal back and press into place. Next, install the bottom of the seal by creating a short turn at the bottom of the tub channel and ensuring the seal extends to the

locator ridge at the bottom of the tub. Then align and gently press the seal into the channel in only a few spots. Next, close and latch the door to allow the gasket to seat properly into the channel.

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

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.
