SECTION TWO THEORY OF OPERATION CONTROL PANEL MODEL: GU1200XTK 2 4 8 CYCLES CYCLE SELECTION CHART Select the wash cycle and options desired. Upon selecting the cycle key, the cycle will begin immediately. Cycles may be changed at any time, during the first fill. Options can be selected or changed at any time. High NOTE: The last options used will be recalled from memory automatically upon selecting a cycle, (if the option is valid with the cycle selected).
Canceling a Cycle Anytime during a cycle, press The dishwasher starts a two minute drain (if needed.) Let the dishwasher drain completely. The light turns off after two minutes. To Stop the Drain NOTE: The Soil Sensor monitors water pressure at the output of the drain pump. Cycle time and/or water usage can vary from the numbers above as the sensor adjusts the cycle for the best wash performance. Water pressure varies depending on the soil concentration in the accumulator.
ADDING ITEMS DURING A CYCLE Items can be added any time before the main wash starts. Open the door and check the detergent dispenser. If the cover is still closed, add items. To Add Items: 1. Lift up the door latch to stop the cycle. Wait for the spraying action to stop before opening the door. 2. Open the door. If the detergent dispenser cover is still closed, add the item(s). 3. Close the door firmly until it latches. The dishwasher resumes the cycle after a five (5) second pause.
Control lock Use the Control Lock to prevent the dishwasher from accidentally being turned on. Use the ControlLock, also, to prevent accidental cycle or option changes during a cycle. When the Lock LED is lit, all buttons are disabled. NOTES: • • The dishwasher door can be opened while the controls are locked. The lock can be turned on while the dishwasher is running. To Turn on the Control Lock: Press and hold Air Dry for four (4) seconds. The LOCK LED will glow.
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 and thermal hold portions of the cycle. Wash action continues while sensing occurs.

FUNCTION DESCRIPTION The washing action of the Point Voyager Dishwasher performs more work and maintains higher performance 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 control board which adjusts cycle functions to optimize washing performance. 8 10 11 6a 7 2a 7 2b 2c 4 3 6b 5 11 Wash/Rinse Function 1. 2. 3.
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 accumulator screen while the water is drained from the unit. (2) 3. Second, negative pressure in the main wash pump inlet chamber keeps the check valve closed, allowing the drain pump to remove soiled water from the accumulator.
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 10 seconds while the wash pump is operating in a wash or rinse mode. The accumulator screen will be cleaned from jets on the underside of the lower spray arm.

HOW TO USE THE COMMON CYCLE TIME CHART The Common Cycle Time Chart reproduced on pages 26 and 27 of this Job Aid can be found on the Tech Sheet supplied with each dishwasher. The Tech Sheet is located behind the access panel at the bottom of the unit. The Common Cycle Time Chart appears to be more complex than a typical Esterline Chart. This is a result of the greatly expanded number of cycles and cycle variations possible with electronic controls as opposed to previous electro-mechanical controls.

COMMON CYCLE TIME CHART NOTES NOTE 1 – CYCLE MODIFICATIONS 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 modifications made to the cycle depend on the cycle and options selected as well as the sensor inputs. Note the interval skip arrows and thermal hold temperature changes on the time chart for each version of the cycle.
NOTE 2 – APF ENABLED INTERVALS 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. The control monitors the pressure switch (soil sensor) input during each of the APF enabled intervals in the cycle (see time chart).
NOTE 5 - NUMERIC CYCLE TIME DISPLAY Some models with numeric cycle time displays show an animated spinning clock pattern during the first four intervals of the cycle (intervals 45-42) while sensor based cycle modifications (and true time remaining) are being determined. Other models simply display the worst case cycle time remaining (in minutes) until the end of interval 42. See the Model Specifics Table to identify models with numeric displays and which models exhibit the animated clock pattern.
NOTE 9 - SOAKING PAUSE INTERVAL — ENERGY STAR NORMAL CYCLE ONLY Intervals 13 and 32 are mid-cycle soaking/pause intervals and are only used in the Energy Star light soil/non-sensor version of the Normal cycle. The control stops washing and turns all loads off except the vent in these intervals. The intent is to let the wash water that’s on the dishes soften and loosen the food soil that’s on the dishes, energy free.
