Operation
• Check that the pump inlet filter has been placed in the correct position if it was removed for cleaning.
• Check that the overflow stand pipe is inserted correctly in its outlet.
• Close door.
• Turn power switch to “PROGRAM” (switches should now illuminate).
• The dishwasher will fill automatically.
• The booster indicator should come on to indicate that the inlet water to the rinse and fill system is being
heated to the required rinse temperature (usually 165°F/ 74°C).
• When the booster water has reached the correct temperature, the corresponding light switches off and the
wash tank light comes on if the wash water temperature is not sufficiently hot (usually 165°F / 74°C).
• At initial daily start, allow about 10 to 20 minutes for machine to stabilize water temperatures to their proper
temperatures.
Note: After warm-up, one initial wash cycle should be performed to thoroughly mix soap and water
and be sure unit is fully warmed up and ready to wash properly.
• After initial warm-up, when all heater lights are off, the dishwasher is ready to wash.
Note: If door is opened during heating, or operation, the safety control will turn off the timer and
heater controls. Washing or rinsing will restart from beginning of wash cycle.
• Open the door, insert the basket with the items (dishes, glasses, etc.) noting that heavy food residue
has been removed. (If the automatic soap injection system is not used, pour the proper amount of liquid
detergent manually into the wash tank). Close the door.
• To start the washing program, select the program desired and press the START button. The automatic
program commences, with the green program indicator light in the program selector switch changing from
flashing to steady.
Note: This unit is equipped with a “positive rinse temperature control and will not advance from
wash to rinse unless the rinse water is at the preset temperature (usually about 195°F / 91°C).
• When the program is finished, the green program light returns to flashing.
• Promptly open the door and remove the basket with the clean items. Use caution with hot items.
• Allow to dry.
If, after washing, there are stains from dirt or water spots, the cause may be one of the following:
• Wrong ratio of detergent to water.
• Rinsing water with very high mineral content.
• Improper quantity of rinse-aid.
• Wrong arrangement of items in the basket.
• Low water pressure during rinsing.
• Low water temperature during washing.
• Clogged or miss-positioned filters.
• Clogged jets.
Note
• The wash temperature must be within ≥ 74°C & ≤ 84°C and the rinse temperature must be within ≥ 74°C &
≤ 91°C.
• Please check during the operation that the rinse water pressure is within its limits (20 ± 5 psi).
