Operation Procedures
The operation of your dishwasher will be more efficient when these procedures are followed:
1. Check that the spray arms and scrap screen are in place.
2. Close the door and depress the front edge of the door latch toward 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:
• 501HT, 501HTN - 66°C/150°F.
• 501LT - 60°C/140°F.
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. Shut the door, and depress the door latch. 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 cycle is completed.
