5.After a 2-3 second pause, the pump drain cycle begins and continues for approximately 30 seconds. Just before this cycle ends the fill valve will come on for 2-3 seconds to flush the wash tank of any remaining detergent.

6.After a 2-3 second pause, the fill valve opens, and the pump starts for the rinse cycle.

Daily Operation Procedures

The operation of your dishwasher will be more efficient when these procedures are followed:

1.Check that the spray arm and scrap screen are in place.

2.Close and latch the door. Push the ON/FILL switch to the ON position. The tank will begin filling with water. This procedure is followed only when the tank is empty.

3.When the tank is full, check the wash tank temperature gauge. Minimum wash temperatures are:

401-HT PLUS, 401-HTN PLUS - 66°C/150°F.

401-LT PLUS - 60°C/140°F.

!CAUTION:

If the wash water temperature falls below the minimums listed above, you must run an empty cycle to refill with fresh hot water.

4.Scrap and preflush all items to be washed, and load the items into the rack. DO NOT OVERLOAD the rack. Wash only one layer of silverware in a rack.

5.Open the door and insert the rack into the machine.

6.Close and latch the door. This will start the wash cycle. The green cycle lamp located on the front control panel will light. This lamp will remain on until the entire wash and rinse cycles are completed.
