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 drain water to a maximum height of 36" (0.9 meter). A 1" ID flexible
hose* is recommended to facilitate maintenance and servicing of the machine. It is important not to reduce the size of
this hose. A 1" check valve*
will be require d.
There should be sufficient hose length to permit the machine to be
pulled out for service.
The drain pump activates automatically during a washing/rinse cycle and functions when the water fill valve is open:
during the fill and rinse cycles.
To manually drain the wash tank, you must:
1. -Turn off the machine (square green button on control panel).
2. -Open the door and remove the overflow pipe.
3. -Press the white button on the control panel, which will activate the drain pump. If the button locks is in the "ON"
position, do not forget to turn the pump "OFF" when the wash water is evacuated.
The most common causes of drain pump failure are:
1. -The customer flushed debris down the drain and blocked the impeller in the pump. Removing the impeller cover
and clearing the obstruction generally restores normal pump function.
2. -The customer forgot to turn "OFF" the drain pump (older models). The pump ran dry or overheated, seized or
burned out. Newer models have a non-locking button which must be held for the drain pump to operate.
