RECIRCULATION AND DRAIN

Water Pump/Pump Motor

The pump is directly driven by a separate reversible 120 VAC 60 Hz motor. By being reversible, the motor provides for two separate operations of the washer.

Outer Tub

The Outer Tub sump plays a role in the drain and water recirculation function The sump area includes two check balls that direct water flow when the water pump operates in the drain and recirc direction.

Recirculation

When water is present in the tub, the check balls will float in the proximity of the recircula- tion and drain sump ports. Water weight or water pressure applied to the ball(s) will cause them to drop away from their respective port or seal off the port.

During the Recirculation Mode, the pump motor turns counter-clockwise (as viewed from underneath the washer). This causes the water pump to draw water from the tub through the drain sump port, forcing the recirculation check ball to seal the recirculation sump port and force water through the recirculation tube outlet. Water is recirculated back into the tub onto the load.

Drain Check Ball drops from weight of water in tub and negative pressure from pump

Recirculation Check Ball seals off the Recirculation port, due to positive pump pressure, forcing water to flow out of Recirculation Feed Tube
