7 Sensing/Soaking The dishwasher senses the soil level on the dishes. Soil level determines the length of some cycles, the amount of heat added to the wash and the number of rinses needed in the cycle for the load. It also senses the temperature of the water during thermal hold water heating periods. SENSING/SOAKING glows during the soil sensing an[...]

9 FUNCTION DESCRIPTION The washing action of the Point V oyager Dishwasher performs more work and maintains higher per- formance with reduced energy consumption. This is accomplished with the following: 1) A redesigned wash system using separate wash and drain pumps. 2) A soil sensor and thermistor which monitor washing conditions. 3) An electronic[...]

10 Drain Function 1. During the Drain function, a separate drain pump motor is started while the main wash pump motor continues to operate for 1 minute. (1) This accomplishes three goals. 2. First, the jets on the underside of the lower spray arm continue to flush soils from the accumu- lator screen while the water is drained from the unit. (2) 3. [...]

11 3 2 Automatic Purge Filtration 1. The Automatic Purge Filtration feature may be invoked if the soil sensor detects excessive soils. This can occur during selected wash or rinse functions. APF mode provides one or more purges of excess soils trapped in the soil accumulator at specified intervals in a cycle. 2. The APF mode operates for a total of[...]

30 Using the Common Cycle Time Chart T o confirm the correct operation of a cycle or properly diagnosis a malfunction, the following informa- tion must be determined: • Does the model have a Soil Sensor? • What cycle was chosen? • What Cycle Option was chosen? • What is the first fill water temperature? (Quick Clean / T ime Saver Cycle only[...]

31 COMMON CYCLE TIME CHART NOTES NOTE 1 – CYCLE MODIFICA TIONS BASED ON SENSOR INPUTS The control monitors food soil and temperature sensors during the first four intervals of the cycle (intervals 45-42) to determine what sensor based cycle modifications are appropriate. The modifica- tions made to the cycle depend on the cycle and options select[...]

32 NOTE 2 – APF ENABLED INTERV ALS The APF ( Automatic Purge Filtration) wash system allows the control to continuously filter and flush food soil out of the pump during “APF enabled” intervals scattered throughout each cycle and do it without interrupting the cycle.
