Special Feature

Soil Settler

This model is equipped with a soil settler system. The inlet to the soil settler funnel is located to the right and just behind the lower spray arm assembly.

Since this inlet is located in an area that is relatively free of water turbulence, food particles washed from the dishes can collect in this area and fall through the funnel and accumulate in the collector .

Food particles continue to collect as long as the dishwasher is in the Wash mode.

(Fig. 1-1)

COLLECTOR

PUMP INLET

HOSE

Fig. 1-2

When the Wash cycle is finished, the dishwasher will reverse the direction of the motor and enter the Drain mode. Water is pumped into the port at the bottom of the soil collector during the Drain cycle causing the ball in the collector to rise against the opening in the bottom of the funnel. Water flows through and out of the collector through the top port and into the drain line. collected during the Wash cycle are carried out with the drain water. When the Drain cycle ends and the pump stops running, the ball settles to the bottom of the collector.

Fig. 2-1

POWER CLEAN FILTER 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. As water and soils return to the lower pump area, the chopper blade grinds the particles into smaller sizes that then pass through the perforated plate into the upper chamber of the pump. The pump impeller causes the soil ladened water to be lifted and moved to the outer edges of the pump chamber where they are forced into the separator. Clean water is then forced up through the spray arms and fine mesh screen.

3. When the drain cycle begins, the drive motor changes direction. This relieves the pressure on the two check balls, opening the drain system.

4. Water is pumped from the tub carrying soils from the separator into the drain sump of the pump.

(Fig. 2-4)

5. Soiled water is pumped out of the dishwasher through the check valve and drain hose.

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). If the water temperature reaches 140ºF or the thermostat closes. The heater is turned “off”. Time continues to elapse and all other output states remain the same until the prescribed interval time has elapsed.

Note 2: Pre-Wash Thermal Hold This thermal hold is only executed during the heavy and pots-n-pans cycles. The thermal hold setpoint is 140ºF or thermostat contact closure and the default time is 25 minutes.

Pressure switch contact closure at any time during this interval causes the cycle to jump to interval 37. Immediately.

Note 3: Pre-Rinse Sense Interval Pressure switch contact closure at any time during this interval causes the cycle to jump to interval 31. 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 heated wash interval for the normal cycle. If the water temperature reaches 140ºF or the thermostat closes. The heater is turned “off”. Time continues to elapse and all output states remain the same until the prescribed interval time has elapsed.

Note 4: Pre-Rinse Thermal Hold This thermal hold is only executed during the heavy and pots-n-pans cycles and only occurs if the pressure switch trips during the sense or thermal hold intervals of the pre-wash the thermal hold setpoint is 140ºF or thermostat contact closure and the default time is 20 minutes. Pressure switch contact closure at any time during this interval causes the cycle to jump to interval 31. Immediately.

Note 5: Main Wash Thermal Hold This thermal hold is automatic for the pots-n-pans and heavy cycles (set point = 140ºF). For the normal cycle. This thermal hold is invoked by selecting the power scour or high temp wash options (Set Point = 140ºF) or as a result of the pressure switch tripping during the pre-wash (Set Point = 130ºF). For the low energy wash and quick wash cycles. This thermal hold is invoked by selecting the high temp wash option (Set Point = 140ºF). In all cases, the default time for this thermal hold is 20 minutes

Note 6: Main Wash Recirculation Interval The power scour option increases the length of this interval to 10:00 for the pots-n-pans and heavy cycles.

Note 7: Final Rinse Thermal Hold This thermal hold is automatic for all cycles except the china wash and rinse only cycles (Set Point = 140ºF). For the china wash cycle, this thermal hold only occurs if the pressure switch trips during the pre-rinse (Set Point = 130ºF). In all cases the default time is 25 minutes.

If the sani rinse option is selected, then the set point for this thermal hold becomes 150ºF and the default time changes is 25 minutes.

Note 8: Air Dry The default status for the dry period is heat dry “on”. Selecting the “air dry” option causes the heater to be turned “off” during this interval.

Note 9: China Dry Interval When the china wash cycle is selected, the heater will be turned off during this interval.

Note 10: Option LED’s When a valid option is active, then the LED for the option will be “on”.

Note 11: Sani Complete LED When the “sani rinse” option has been selected and completed. A “sani complete” indicator is illuminated at the end of the cycle. During a cycle in which

“sani rinse” has been selected, the target thermal hold temperature for the “sani rinse” option must be satisfied and maintained. If this condition is not satisfied (because the final rinse thermal hold default time elapsed or power to the dishwasher was lost at any time during the remainder of the cycle that follows due to a door opening or AC line failure) then the sani complete indicator will flash on and off at the end of the cycle. Opening the door or pressing any key will turn the indicator off in either case.

Note 12: Motor Drain Phase Winding This output is only “on” when the motor is starting in the wash mode. When the control has determined that the motor has started, the wash phase winding will be turned “off”.

Note 13: Motor Drain Phase Winding This output is only “on” when the motor is starting in the drain mode. When the control has determined that the motor has started. The drain phase winding will be turned “off”.

Note 14: Diagnostic Sensor Input Test The soil sense pressure switch input is active during this interval. Pressure switch contact closure at any time during this interval causes the cycle to jump to the next interval. Immediately.

Note 15: Diagnostic Thermal Hold The default status for this thermal hold is “on”. The thermal hold set point is 140ºF or thermostat contact closure and the default time is 60 minutes. After 60 minutes, the thermal hold is terminated and normal cycle timing resumes. The diagnostic test cycle advance function can also be used to terminate this thermal hold.

Note 16: Cycle Complete A clean indicator will be on at the end of this cycle. Opening the door or pressing any key will turn the indicator off.

Note 17: Diagnostics Cycle -- Thermostat/Thermistor Indicator The “clean” LED will turn on during the display test at the beginning of the cycle (interval 11) and again at the conclusion of the cycle (interval 2) regardless of what it detects on the thermistor input. The “clean” LED will be on in intervals 1 through 8 of the cycle whenever an “open” (resistance greater than 200K OHMS. +/- 50K OHMS) is detected on the thermistor input by the control. Consequently, if a normally open operating thermostat were to be installed on the thermistor input, the “clean” LED would be on throughout the cycle until the thermostat tripped (e.g., during the thermal hold); With a thermistor installed, the clean LED would only be on in intervals 10 and 0. Because the thermistor always has a resistance of between 50 K-OHMS and 8 K-OHMS under normal operating conditions.

Options Water Heat: Forces a thermal hold to occur in the main wash regardless of soil level. The set point for this thermal hold is 140ºF. This option is automatic with the potsn-pans and heavy cycles. It is not available on china wash or rinse only cycles.

Sani Rinse: Raises the setpoint temperature of the thermal hold in the final rinse to approximately 65ºC/150ºF. This option is not available with china wash, quick wash & rinse only cycles. This option is only possible on models that use a thermistor.

Air Dry: Opens the circuit to the heater element during the dry period of the cycle. This option is not available on quick wash or rinse only cycles (which have no dry period).

Power Scour: Inserts additional heated wash time into the pots-n-pans, heavy and normal cycle pre-wash sequence (interval 39 becomes a 16 minute, thermostatically controlled, heated wash). Turns the heater on in interval 33 of the normal cycle pre-rinse, invokes a thermal hold in the main wash of the normal cycle and extends interval 23 to 10 minutes in the pots-n-pans and heavy cycles. This option is not available on low energy, china wash, quick wash or rinse only cycles.

DIAGNOSTICS AND SALES DEMO TIMING CHART NOTES

1. The diagnostics test cycle starts at interval 11 and concludes at interval

2. To initiate the diagnostics test cycle, press the following sequence of keys within 10 seconds:

High Temp Wash, Air Dry, High Temp Wash, Air Dry

or

Power Scour, Air Dry, Power Scour, Air Dry

The diagnostics test cycle may be manually advanced to the next interval by pressing the pots & pans key. To exit diagnostics, press cancel.

2. The sales demo cycle consists of a single 6-minute wash interval which starts at interval 1 and concludes at interval 0. To initiate the sales demo cycle, press the following sequence of keys within 10 seconds:

High Temp Wash, Air Dry, High Temp Wash, Air Dry, High Temp Wash

or

Power Scour, Air Dry, Power Scour, Air Dry, Power Scour

3. The diagnostics test cycle executes a soil sensing interval at interval 9 to test the soil sensing circuit. The sensing LED is illuminated through out this sense interval.

If the soil sensing pressure switch is tripped at any time during this sense interval, the control will immediately terminate the sense interval and proceed with the remainder of the diagnostics cycle.

If the time limit for this sense interval elapses without detecting soil, the control simply proceeds with the remainder of the diagnostics cycle.

4. The diagnostics cycle suspends cycle timing and executes a thermal hold at interval 7. The thermal hold interval is terminated and cycle timing resumes when the water is heated to the desired set point temperature (60ºC/140ºF). The maximum default time limit elapses (1 hour), or the cycle is manually advanced to the next interval by pressing the pots & pans key. The water heating LED is illuminated during the thermal hold.

5. The clean LED is illuminated at the end of both the diagnostics test cycle and the sales demo cycle. The clean LED can be extinguished by opening the door or pressing any key.

6. During intervals 9 through 3 of the diagnostics cycle, the clean LED is

illuminated whenever the control detects a resistance of greater than approximately 45 K-OHMS on the thermistor/ thermostat circuit. This feature is intended to help determine whether a thermostat or thermistor is installed. A thermostat with normally open contacts would trigger the clean LED (until the thermostat is tripped). Under normal operation, the resistance of the thermistor is always less than 45 K-OHMS and would not trigger the clean LED.

7. The wash and drain auxiliary windings are only “on” when the motor is being started. When the control has determined that the motor has been started satisfactorily, the auxiliary winding will be turned “off”.

8. Entering the key sequence high temp wash (or power scour), air dry, high temp wash (or power scour), air dry, after a cycle has started, will enable the pots-n-pans key rapid advance feature. This will allow service to rapidly step to any interval of the currently running cycle.

Other Control Features:

Cancel/Drain: Terminates current active cycle and clears cycle selections. Executes 2-minute drain upon first selection if water is likely to be left in sump. Subsequent selections toggle between 2-minute drains and going to standby.

Control Lock: The control lock LED is illuminated and all keys of the keyboard are disabled whenever the control lock feature is invoked by the customer. The control lock feature (and LED) can be turned on or off by the customer at any time by holding down the air dry option key for 4 seconds.

Delay Start: Allows the customer to delay the start of a cycle by up to 6 hours. Each press of the delay key increases the delay time selection by two hours. The selected delay period will begin clocking down upon selecting the cycle key. The cycle selected will begin automatically upon completing the delay period.

Error Messages:

Stuck Key: If the control detects that a key is stuck in the depressed position, dishwasher operation will be suspended and the control will flash the LED associated with that key until the condition is corrected. If a key without an LED is stuck or multiple keys are stuck, the control will flash the lock-out LED.

Section Three

Model GU980SCG

POWER CLEAN FILTER 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.

(Fig. 3-1)

2. As water and soils return to the lower pump area, the chopper blade grinds the particles into smaller sizes that then pass through the perforated plate into the upper chamber of the pump. The pump impeller causes the soil ladened water to be lifted and moved to the outer edges of the pump chamber where they are forced

into the separator. Clean water is then forced up through the spray arms and fine mesh screen.

3. When the drain cycle begins, the drive motor changes direction. This relieves the pressure on the two check balls, opening the drain system.

4. W ater is pumped from the tub carrying soils from the separator into the drain sump of the pump.

5. Soiled water is pumped out of the dishwasher through the check valve and drain hose.
