MODELS WITH INTERNAL DRAIN PUMPS

The power cord on the internal drain pump is connected to a 120 VAC wall outlet. The ice maker is then connected to the 120 VAC outlet on the drain pump. If the drain pump fails, or if the drain becomes blocked, power is shut off to the 120 VAC outlet on the drain pump.

When the unit is first plugged in, the drain pump will run for 20 seconds. The power can be disconnected and reconnected to verify that the pump is operating properly.

Water from the ice maker reservoir, or melting ice from the bin, drains down the bin drain tube

into the pump inlet, and then into the drain pump chamber. As the water level rises, it bridges the “full” contacts, and the pump starts to run. The pump discharges the water through the outlet and the check valve. When the “full” connection is removed, the pump runs for an additional 12 seconds to empty the tank.

If the water level in the drain pump continues to rise, due to a slow or blocked drain, or a blocked vent hose, and touches the “overfill” contact, power will be turned off to the drain pump’s 120 VAC outlet, causing the ice maker to turn off.
