DRAIN PUMP OPERATION
Models 727, 737, F-16DP and F-18DP are factory built with drain pumps. A square white button
on the control panel beside the green power button also evidences this feature. All other models
have a gravity drain.
Drain pump equipped models will pump the waste water to a maximum height of 36” (0.9 meter). A
1” ID flexible hose of sufficient length is provided to facilitate maintenance and servicing of the
machine. It is important not to reduce the size of this hose. A 1” check valve* may be required. There
should be sufficient hose length to permit the machine to be pulled out for service. Drainage time
should not exceed 1 minute.
The drain pump activates automatically during a rinse cycle and functions when the water fill valve
is open: during the fill and rinse cycles. This allows the removal of excess water entering the unit.
To manually drain the wash tank, you must:
1. -Turn off the machine (square green button on control panel).
2. -Open the door, remove the basket, and remove the overflow pipe (also known as stand pipe).
3. -Press and hold the white button on the control panel, which will activate the drain pump.
Release the button when the water has been discharged.
The most common causes of drain pump failure are:
-Debris was flushed down the drain and blocked the impeller in the pump. Removing the impeller
cover and clearing the obstruction generally restores normal pump function.
-The drain hose, at the back of the unit, is restricted.
IMPORTANT! Pump failure caused by debris blockage is NOT covered by the warranty.
