OPERATION SUMMARY
ActionResult
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
