Check all the plumbing for leaks. Also, check the drain plumbing for leaks and be sure that the drain will handle the drain water flow (15 gal/min-56.8 liters/min) from the dishwasher.

After the drain and the plumbing connections are checked, turn off the dishwasher power switch.

Drain the dishwasher

Make sure the dishwasher power switch is turned off.

When power is switched to the OFF position machine will drain automatically for ten minutes.

Remove the scrap screens and check the drain located in the bottom of the dishwasher wash tank.

OPERATION SUMMARY

Action Result

OPERATION

1. Push the On/Off power switch “UP” to the ON position. Dishwasher fills automatically.

2. Wait approximately 10 minutes for the wash tank heater to heat the water. Then, check the reading on the wash water temperature gauge.

3. Prescrap and load the ware into the dishrack.

4. Open the doors. Insert a dishrack of soiled ware. Fully close the doors.

Opening the doors anytime during the automatic cycle stops the dishwasher. Closing the doors will resume the cycle where it left off.

5. Check the final rinse temperature gauge reading during the 14 second final rinse cycle.

1. The power indicator light illuminates. The wash tank heater (D-HBT/H1T) and the booster tank heater (D-HBT) begin to heat.

2. The wash water temperature gauge should indicate a minimum of 150°F/66°C for D-HBT, D-H1T.

3. Ware should be placed edgewise in the peg rack. Cups and bowls should be placed upside down in the flat rack. Silverware should be spread evenly in a single layer in the flat rack.

4. In cycle light illuminates as the dishwasher begins a selected automatic cycle. The total cycle times are listed below:

1 minute = 45 second wash 2 minute = 1 minute 37 second wash 4 minute = 3 minute 37 second wash 6 minute = 5 minute 37 second wash

5. The final rinse temperature gauge should indicate a minimum of 180°F/82°C for D-HBT/ D-H1T. The optimum final rinse temperature range is between 180-195°F/82-90°C.

6. Check the incoming water pressure during the 14 second final rinse cycle.

7. The selected automatic cycle ends.

8. Open the doors. Remove the clean rack. Insert another rack of soiled ware. Fully close the doors.

9. Turn power OFF at the dishwasher. Clean the scrap screens. Clean the dishwasher after each meal period or every two hours of operation. After initial draining of tank, if you should need to continue draining, flip power switch to ON then OFF to redrain.

6. The water pressure gauge should indicate a flowing pressure of 20-22 PSI/138-151.8 kPa. A pressure reducing valve (PRV) is required if flow pressure exceeds 20-22 PSI/138-151.8 kPa.

7. The in cycle light goes out.

8. The selected automatic cycle begins again.

9. Dishwasher drain valve opens for ten minutes automatically. Periodic cleaning reduces detergent consumption and improves washing results.
