THEORY OF OPERATION MODEL: GU1200XTK CYCLE SELECTION CHART Select the wash cycle and options desired. Upon selecting the cycle key, the cycle will begin imme- diately. Cycles may be changed at any time, dur- ing the first fill. Options can be selected or changed at any time. -
Page 8: Canceling A Cycle
NOTE: The Soil Sensor monitors water pres- sure 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 de- pending on the soil concentration in the accumu- lator. -
Page 9: Option Selection
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: Lift up the door latch to stop the cycle. Wait for the spraying action to stop before opening the door. -

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. - Page 12 High High High º 130 F º (54 C) Rinse High Purge Rinse...

Page 13: Function Description
FUNCTION DESCRIPTION The washing action of the Point Voyager 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. - Page 14 Drain Function 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. 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.

Page 15: Automatic Purge Filtration
Automatic Purge Filtration 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. The APF mode operates for a total of 10 seconds while the wash pump is operating in a wash or rinse mode. - Page 16 -- NOTES --...

Electrostatic Discharge (ESD) Sensitive Electronics ESD problems are present everywhere. ESD may damage or weaken the electronic control as- sembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress. •... - Page 19 Removing the Electronic Control Board The electronic control board is located inside the console at the top of the dishwasher door. Disconnect the ribbon connector and the wiring harness connectors from the electronic control board. (Fig. 3-2) Use a flat bladed screwdriver to depress the holding tabs at the left end of the control board assembly while pulling up.

Removing the Pump Assembly The entire pump assembly can be removed from inside the dishwasher tub. Remove the access and toe panels from underneath the dishwasher door by re- moving the two (2) screws securing it to the dishwasher frame. (Fig. 3-15) Disconnect the wiring harness connectors from the drive motor and pump motor terminals, the soil sensor and the thermistor. - Page 25 Removing the Pump Motor With one hand, press back on the plastic tab that holds the pump motor from rotat- ing. (Fig. 3-18) With the other hand, rotate the pump mo- tor counterclockwise approximately ¼ turn. The pump motor will now be free of the pump assembly.
- Page 26 The check valve, located between the wash motor and the drain can be removed with a pair of needle nose pliers. (Fig. 3-24) NOTE: When replacing the check valve, simply drop it in place. The inlet protector will seat the flapper valve properly when it is reinstalled.

Removing the Impeller from the Wash Motor The impeller is attached to the wash motor and can be removed once the wash motor is removed from the pump base. Place the end of a flat-bladed screwdriver into the back of the wash motor to hold the armature of the motor from turing while un- screwing the impeller clockwise. - Page 28 Remove the three (3) screws securing the hinge plate to the front of the dishwasher inner door panel. (Fig. 3-31) Open the door slightly. Hold onto the door assembly. With the counterbalance spring removed, the door will drop open easily. Lift the door up to disengage it from the hinge pin (Fig.

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. - Page 33 There are 45 intervals in the Common Cycle Time Chart. Not all intervals have the same time as- signments from cycle to cycle. An interval may be only seconds long or up to 20 minutes in length. More than one function can take place during an interval.

Page 35: Common Cycle Time Chart Notes
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 modifica- tions made to the cycle depend on the cycle and options selected as well as the sensor inputs. - Page 36 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).
- Page 37 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.
- Page 38 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.
