PUMP AND MOTOR OPERATION 1. Once the tub has filled with hot water the motor begins to rotate forcing the water up through the pump chamber and out through the spray arms. Two spray jets on the underside of the lower spray arm direct water down onto the fine mesh screen of the pump housing to clear soils that may collect there during the wash cycle. 2.

Section Three DIAGNOSIS AND TROUBLESHOOTING TROUBLESHOOTING GUIDE Model DU910PFG PRECAUTIONS TO BE OBSERVED WHILE TROUBLESHOOTING Always check wiring harness and connectors before initiating any test procedures. Disconnect electric power from the dishwasher before touching the printed circuit boards or re-seating wire connectors. Voltage checks should be made by inserting meter probes beside the wires in the connector blocks with the electric power source on and the connector block plugged in.

CYCLE TIMING CHART NOTES Note 1: Pre-Wash Sense Interval Pressure switch contact closure at any time during this interval causes the cycle to jump to interval 37. Immediately. For the normal cycle, the heater is “off” during this interval. For the heavy and pots-n-pans cycles the heater is “on” during this interval. The power scour option changes this interval to a 16 minute heated wash interval for all 3 cycles (normal, heavy and pots-n-pans).
