Pump Assembly
The pump assembly is driven by a synchronous attached by a worm gear clamp to the discharge
motor. Rotation is in the counterclockwise of the drain pump. The drain is then routed up the
direction at 3600 RPM. The motor drives a pump side of the dishwasher and attached to the side
which supplies 100 percent filtered water at a of the tub. This drain loop insures that an air
rate to approximately 12 GPM to one spray arm pocket cannot form near the drain pump and

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.
