Introduction

The new GE Proﬁ le PDW8900 Series, PWDW9700 Series, and PDW9900 Series dishwashers incorporate the following new features for 2005:

SmartDispense

•

- A bulk liquid detergent dispense assembly is introduced with this dishwasher. It consists of a dispense reservoir mounted within the inner door panel, a liquid level sensor connected to a Low Detergent LED on the control panel, and a positive displacement pump to inject the optimal amount of detergent into the dishwasher during each cycle. A water hardness selection mode permits the calibration of the location's water hardness.

Single Rack Wash

•

- In addition to the two rack wash cycles, this GE Proﬁ le dishwasher has a Single Rack Wash which bypasses the lower spray arm, directing the cleaning power to the upper rack only. Water is dispensed from the middle and upper wash arms only.

Smart Fill - The wash system has been changed to a low ﬂ ow design. The wash, dry, and noise

•

performance have all been improved. Smaller jets on the spray arms require less water to keep the pump primed. Less water allows the Calrod to heat the water to a higher temperature, improving both wash and dry performances.

Angled Rack Dry - A new top rack features two adjustable-angle dividers. This prevents rinse

•

water from puddling, allowing it to run off the bottoms of stemware, glasses, and cups.

Water Hardness Test and Calibration

SmartDispenseTM Calibration

Test Water Hardness

The automatic liquid dishwashing detergent dispenser (SmartDispenseTM) dispenses the optimum amount of detergent to clean the dishes. This amount of detergent introduced during each cycle is based on the soil level of the dishes and the hardness of the water. Therefore, the correct water hardness setting is very important for both optimum cleaning of dishes and detergent usage.

Prior to the ﬁ rst use, this dishwasher must be calibrated for water hardness. This process requires the use of a water hardness test strip (part # WD01X10295). This part can by shipped by mail.

The 4 light green stripes will change color. The harder the water, the more stripes will change from green to red.

Water hardness should be tested following the instructions on the test strip package shown above.

Note: If all stripes remain green after the test, the outcome is "0 RED". The value to be entered into the dishwasher is "1".

Convert the test reading according to the table below.

The calibration process will differ slightly depending on whether the dishwasher is front mount control (PDW8000 series) or top mount control (PDW9000 series).

Front Mount Control (PDW8900)

Dishwasher must be in standby mode. Close and latch the door. Press normal wash to illuminate the lights on the control panel.

Press Cookware pad and Delay Hours pad together and hold for 3 seconds.

The current hardness setting will be shown on the Time Remaining display.

Enter the value from the test strip using the

Cookware pad to increase the value or the Normal Wash pad to decrease the value.

Press the Start/Reset pad to return the dishwasher to normal operation. The last displayed value will be saved as the water hardness value.

Top Mount Control (PDW9700, PDW9900)

Dishwasher must be in standby mode. Press up arrow to wake up control and illuminate the lights on the control panel.

SmartDispense

SmartDispenseTM is a bulk liquid detergent dispense assembly consisting of the following components:

Detergent Reservoir - Mounted within the inner

•

door panel

Detergent Level Sensor - Connected to a Low

•

Detergent LED on the control panel

Positive Displacement Pump - Injects

•

the optimal amount of detergent into the dishwasher during each cycle.

Detergent Reservoir

Note: The SmartDispenseTM system can only be

used with liquid or gel automatic dishwasher detergent.

To ﬁ ll the reservoir, push down on the cap covering the reservoir to engage the ratchet, then turn it counterclockwise to open.

To remove the reservoir:

Note: Removing the reservoir access collar causes

structural damage to the collar. It must be replaced with a new part # WD35X10059.

Remove the door panel. (See Door Panel.) Insert a small ﬂ at-blade screwdriver into the slot in the side of the retaining collar and push the screwdriver handle counterclockwise while turning the reservoir access collar counterclockwise a quarter turn. Remove the retaining collar. Unplug the tube from the reservoir outlet and disconnect the sensor from the control module.

Position the door at a 30 to 45 degree angle. Fill the reservoir with a liquid automatic dishwasher detergent until the detergent reaches the threads of the reservoir access. The dispenser will hold approximately 45 ounces of liquid dishwasher detergent (about 1 to 2 months supply).

Note: The dispenser tank comes as an assembly. It includes the sensor with wire harness, gasket, and retaining collar. The complete assembly part number is WD35X10058.

Place the cap on the reservoir access threads, push down, then turn clockwise until the cap is tight.

Detergent Level Sensor

Light will turn on when time to refill

The SmartDispenseTM detergent level sensor consists of a single level detection continuity sensor and includes the following components:

•

a grommet seal

•

a low detergent LED indicator light

•

a wire harness.

When the detergent in the reservoir drops below the continuity sensor, a signal is sent to the control board and the low detergent LED indicator light is turned on. The light indicates 3 to 7 wash cycles left before the detergent reservoir is completely empty.

Approximate Detergent Use

The SmartDispenseTM positive displacement pump consists of a continuous ﬂ exible tube running from the detergent reservoir to the inner door detergent outlet. The tube runs around the inside edge of the pump housing. A 3-roller impeller ﬁ ts tightly into the center of the pump housing with each of the 3 rollers squeezing the sidewall of the tube. As the impeller is driven counterclockwise by the motor, it squeezes out a predetermined amount of detergent for each 1/3 revolution of the impeller.

The dispenser pump operates on 120 VDC. During each pre-wash cycle, the pump is energized for 5 seconds, dispensing 4ml of detergent.

The electronic control uses two inputs to determine the total amount of detergent dispensed during the main wash cycle:

• Soil Level determined by the turbidity sensor

• Water Hardness as calibrated for the location

A water hardness selection mode permits the calibration of the water hardness for the location at installation. (See

Calibration.)

Water Hardness Test and

To determine the amount of detergent to dispense during the main wash, the control uses the following formula:

4ml x Number of Pre-washes

+ 25ml + Additional Quantity for Hardness

The additional quantity is a predeﬁ ned quantity of detergent based on the water hardness level programmed into the control.

Disconnect the wires and remove the pump.

Customer Purge of the Bulk Dispenser Tank

When to Purge the Bulk Dispenser Tank

Only liquid or gel automatic dishwashing detergent can be used in the bulk dispenser. The dispenser must be purged if the consumer puts hand dishwashing detergent or a rinse agent in the dispenser. These products will produce copious amounts of suds, and water leaks will result every time the dishwasher is run until the tank is emptied.

The dishwasher must also be purged if a liquid dishwasher detergent containing chlorine (like Cascade Pure Rinse Formula) and a liquid dishwasher detergent containing enzymes (like Cascade Complete) have been mixed in the dispenser. When this happens, the chlorine destroys the enzymes resulting in poor wash performance. You can tell if the detergent contains chlorine or enzymes by reading the content label on the container.

A chemical reaction also takes place between the chlorine detergent and the enzyme detergent which causes the two liquids to coagulate and buildup around the detergent level sensor. This build up may prohibit the sensor from sending the low detergent signal to the control board and the low detergent light will not be illuminated when the bulk dispenser is empty.

Consumer Purge Cycle

The consumer must enter Service Mode to activate the purge cycle. The purge cycle ﬁ lls the dishwasher for 57 seconds, then energizes the dispenser pump (instead of the main motor) continuously to drain the bulk dispenser tank .

The purge cycle deselects all other options and runs for 65 minutes. The consumer should run the purge cycle 3 times, ﬁ lling the dispenser tank with water for the second and third cycles. Total time is approximately 3 hours.

Follow these steps carefully to have a successful purge run.

The detergent/rinse mod ule au to mat i cal ly dis pens es both the de ter gent and the rinse agent at the ap pro pri ate times. The module is activated 2 times during a wash cycle. Detergent is dispensed at the beginning of the main wash cycle and rinse agent at the beginning of the ﬁ nal rinse. The detergent/rinse module can be activated using the

Service Mode.

The ﬁ rst time the module is activated:

The lever slides up the right-hand path of the connecting rod (1). This action releases the de ter gent cover.

When deactivated (2), the lever returns down the left-hand path and comes to rest under the notch in the center of the connecting rod.

Door Interlock Switch

The door interlock switch opens the L1 circuit when the door is open. The switch is replaced as an assembly.

The door panel and escutcheon must be removed to access the door latch switch. (See Door Panel.)

The door latch switch is held in place by 2 Phillips head screws.

At the second activation (3), the lever lifts the con nect ing rod by the notch. This action lifts the rinse dispenser plunger and re leas es the rinse agent. When deactivated, the lever returns to its original start ing position.

If the door is unlatched while running a wash cycle, the cycle countdown will pause and the vent will open. If unlatched for more than 15 seconds during a wash cycle, the control will beep once every 15 seconds until the door is relatched.

Heating Element

The heating element can be activated using Service

Mode.

It is normal for the stainless steel tub and the inner door panel to retain water droplets even though the dishes are dry.

The dual-wattage heating element produces 875 watts during wash, to help heat the water, and an effective wattage due to cycling of 700 watts during the dry cycle.

It is normal for the heating element to cycle during Heated Dry cycle. The control energizes the heating element continuously for the ﬁ rst 6 minutes. The control then cycles the heating element on for 60 seconds, and off for 60 seconds for the remainder of the Heated Dry cycle.

Selecting Added Heat will energize the heater for the entire time during the last prewash cycle and the ﬁ nal rinse cycle. Circulation time during the ﬁ nal rinse is increased 2.8 times the normal with this option. If selected after the wash cycle has started, the feature will not take effect until the beginning of the next ﬁ ll. This option is not available for the Rinse Only cycle.

Water inlet temperature must be at least 120°F for proper drying. Low water inlet tem per a ture will pre vent proper con vec tion air move ment and increase drying time sub stan tial ly.

Turbidity Sensor

The turbidity sensor is located on the side of the sump.

Turbidity Sensor

The turbidity sensor measures the amount of suspended particles in the wash water in the sump. The control sends the turbidity sensor a pulse width modulated 5-volt signal for calibration and usage during operation.

The control then receives an analog signal of the sensed turbidity, which is processed by the microprocessor.

The thermistor’s resistance has a negative temperature coefﬁ cient . As the temperature increases, the resistance goes down. At 75°F, the resistance is approximately 9.9K Ω. At 140°F, the resistance is approximately 2.8K Ω.

Note: When installing the turbidity sensor, align the key on the sensor with the keyway on the sump.

Key

The Service Mode is the most accurate way to test the turbidity sensor circuit. The turbidity sensor circuit con tains the control module, wiring, and the tur bid i ty sensor.

Turbidity Sensor Strip Circuit

The baseline reading is taken during the ﬁ rst ﬁ ll

when the sump water level is between the

/8-in. gap between the LED transmitter and the

/4- to

receptor. Successive tur bid i ty mea sure ments are sup plied to the control module and used to de ter mine whether any prewash or rinse cycles can be skipped. The sensing LED is on during all prewash cycles and during the ﬁ nal rinse.

Decisions are based on a com par i son of clean water mea sure ments at the beginning of the ﬁ rst ﬁ ll, mea sure ments taken at selected ﬁ lls, and water tem per a ture. By measuring the turbidity level, the control module can conserve energy on lightly soiled loads by skipping un nec es sary cycles.

Note: If the turbidity sensor circuit fails to open or is shorted, the sensing LED on the control panel will not light, and the unit will operate for the maximum amount of time, using the maximum number of wash and rinse ﬁ lls for the selected cycle.

The turbidity sensor also contains the thermistor for automatic temperature controlTurbidity Sensor

Calibrating the Turbidity Sensor

When replacing the turbidity sensor, or if it has been disconnected, always calibrate the turbidity sensor to the control board.

Note: The calibration cycle MUST be entered within 2 minutes of power up.

Press the Normal pad (the up arrow pad on Top Control Models) and the Cookware pad (the down arrow pad on Top Control Models) for 3 seconds or until all LEDs turn on.

The dishwasher will then perform a series of steps. Once the drain cycle starts, calibration is complete and the Start/Reset pad can be pressed to end the calibration cycle. The dishwasher will continue to pump out remaining water and cycle of.

Drain System

Smart Fill System

The drain system consists of the following com po nents:

• Auxiliary drain pump (includes motor and oneway check valve)

• Drain tube

• Check valve (in line with drain tube)

• Drain hose

The inlet cover prevents large particles from entering the sump. Water entering the drain pump is not ﬁ ltered by the ﬁ ne ﬁ lter (metal) or by the sump ﬁ lter (plastic). The drain pump is mounted on the sump and contains a one-way check valve. The drain pump is controlled by the control module and can be activated using Service Mode.

Auxiliary Drain Pump strip Circuit

DRAIN PUMP

30 Ω

J2-8

RED WHITE

The drain pump utilizes a 120V AC motor. The motor should read approximately 30 Ω.

IMPORTANT: The drain system of this dishwasher requires either a high drain loop or an air gap. Installations without either a high drain loop or an air gap will not perform properly.

The Smart Fill system consists of a new silent ﬁ ll hose design and electronicly controlled cavitation sensing (adaptive ﬁ ll).

The new ﬁ ll hose design uses a rigid plastic tube with rubber over mold at both ends. This smaller diameter reduces water ﬂ ow rate and ﬁ ll noise. The required water line pressure is still 20 to 120 psi.

Fill Hose

The cavitation sensing controls the amount of water for each ﬁ ll. The dishwasher ﬁ lls for 57 seconds, then the pump motor starts. The load on the motor changes as water enters and exits the sump. The electronic control monitors this change as motor current ﬂ uctuation and continues to ﬁ ll the tub until the ﬂ uctuations are stable, assuring the sump is full.

Note: The maximum amount of time the electronic control will energize the water valve is 95 seconds.

High Drain Loop

During a normal wash cycle, the water level in the tub will cover the sump screen or be just to the rear edge of the heater bracket. The dishwasher will ﬁ ll with approximately 1.2 gal. of water.

Water Level

Depending on the wash cycle selection, a complete wash cycle will use between approximately 2.5 gal. (Rinse Only) to 10.9 gal. (Cookware - heavy soil level).

Water Valve and Flood Switch

Water Valve Test

The water valve is a 120 VAC solenoid valve that is switched on/off by the control module. The ﬂ ood switch acts as a safety switch ONLY and does not control normal operation of the water valve. The ﬂ ood switch opens the L1 side of the water valve circuit.

The switch is normally open. The weight of the ﬂ ood switch ﬂ oat holds the switch closed. The ﬂ ood switch will not stop the ﬂ ow of water if the valve sticks open from a mechanical failure.

The water valve can be replaced with the dish wash er installed.

WARNING: Disconnect power to dishwasher before servicing water valve and ﬂ ood switch.

The ﬂ ood switch is held in place by 2 Phillips head screws.

Note: The detergent pump will also operate during the water valve test.

1. Attempt to activate water valve using Service Mode. Pump out water as necessary using Service Mode. If an in ter mit tent failure is suspected, activate water valve 5 times using Service Mode. Water valve should stay on for 75 to 95 seconds per ac ti va tion and should not turn on and off during the 75 to 95 second activation time. A normal ﬁ ll will be approximately 1.2 gallons.

2. If the water valve is not operating properly or water level is low, check the following:

• Water valve, ﬂ ood switch, ﬂ ood switch ﬂ oat

and stem, transorb, and then main control. The ﬂ ood switch should open when the water level is approximately

/4-in. above the

base (bottom) of the ﬂ oat dome.

• Resistance through the water valve so le noid

coil is 725 Ω to 1200 Ω.

Control Module

The door panel must be removed to access the control module. (See Door Panel.) The main control is considered a “smart” control, capable of learning the water temperature and turbidity characteristics of the home.

It is normal for the cycle times to vary over a period of time from the factory default settings due to temperature and water quality.

The control module is held in place by a single screw that secures the module to the right side of the inner door panel. (The screw is located on the outside of the inner door panel.)

The module cover is held in place by 5 tabs (see arrows).

Active Vent

The active vent consists of the fan, motor, housing, and vent louver motor.

The active vent helps to reduce the noise level and heat loss when in the closed position. The control module supplies +/- 12 VDC to the vent louver motor. The control module reverses polarity to drive the motor in a clockwise or counterclockwise (open or closed) direction.

The vent closes 8 seconds after the main pump is switched on during the ﬁ rst ﬁ ll cycle and opens during the drying cycle (heated and non-heated). The vent is open during cooldown periods or when the unit is not in use.

If the vent is closed and the door is opened during the wash cycle, the vent will open. When the door is closed again, the vent will remain open for 8 seconds, then close again to ﬁ nish the cycle.

It is normal for water vapor to come through the active vent during the dry cycle. The active vent can be opened and closed using the

The vent louver is held in place by a single screw. Remove the motor from the mount by rotating the

motor 90° in the mount and sliding it out between the tabs.

Note: This also applies to the Rinse Only cycle. Since heated dry is not an option with Rinse Only, the fan will run for approximately 4 hours before turning off.

To access the vent fan and motor, remove the door panel (see Door Panel).

The vent fan and motor housing are held in place by:

• 4 long, silver Phillips head screws.

• 2 short, brass Phillips head screws (see photo).

Single Rack Wash

The Single Rack WashTM bypasses the lower spray arm, directing the water ﬂ ow only to the upper rack. A plastic-covered steel ball, released by a wax motor-controlled magnet, is forced by the water ﬂ ow to block the venturi for the lower spray arm. Cleaning power is directed to the top basket ONLY through the middle and upper spray arms. In Single Rack WashTM, the tub ﬁ lls with approximately 0.1 to

0.2 gals. less than a normal wash cycle.

Normal Wash Cycle: The pump ﬁ lls with water to the level indicated. The magnet on the end of the wax motor holds the ball out of the water ﬂ ow path. The impeller spins counterclockwise to a high velocity. Water ﬂ owing from the impeller outward, ﬁ lls all chambers.

Single Rack WashTM Cycle: The pump ﬁ lls with water to the level indicated. At the same time, the wax motor energizes and pulls the magnet away. This releases the ball from its position at the bottom of the guide rail.

The impeller spins counterclockwise to a high velocity. The water ﬂ ows from the impeller and carries the ball up the guide rail. The ball wedges into the low-arm channel restricting the ﬂ ow from the lower spray arm. The water ﬂ ow is now diverted to only the upper and middle spray arms.

Circulation Pump and Motor

The dishwasher has a new pump design that includes a wax motor, magnet , and a steel ball used for Single Rack WashTM. This pump must be replaced with the same pump design (kit # WD26X10029).

The pump housing contains a molded channel to direct the movement of the ball towards the venturi. The plastic shell which encases the stainless steel ball has ribs to prevent the ball from sticking in the venturi.

The dishwasher must be removed from its in stal la tion to gain access to the circulation pump and motor. The circulation pump can be activated using Service Mode. Refer to sche mat ic or strip circuit for motor resistance value.

Before removing the circulation pump, remove the water from the sump with a syringe.

It is important to remember that the motor does not start immediately when the dishwasher cycle has started (60 seconds after water begins to ﬁ ll). If the motor hums but will not start, make certain the pump impeller is free from obstruction and the motor shaft turns freely.

Wax Motor and Magnet

The wax motor and magnet (part # WD21X10235) are an assembly and are held to the pump housing by 2 Phillips screws. The wax motor operates on 120 VAC. It takes approximately 45 seconds for the magnet to retract far enough to release the steel ball when the wax motor is at room temperature. The wax motor is energized for approximately 1 minute.

The terminals on the induction motor are labeled L1 and N. The motor is thermally protected (internally) through the L1 side. The wiring connector is blue to match the wire leading to the motor. It is designed to ﬁ t only one way on the terminals. Make certain the connector is fully seated when installing.

The replacement motor pump assembly contains a new ball.

Caution: Be sure the ball is in place and held by the magnet before reassembling the unit.

Note: It is important that the hex-head motorhanger screw is tightened securely when reinstalling the circulation pump.

If the dishwasher door is opened during the Single Rack WashTM, the ball will once again be held by the magnet until the wax motor retracts the magnet from the steel ball (approximately 45 seconds).

Factory Test Mode

Always run the factory test mode to calibrate when replacing the turbidity sensor, control module board, and membrane key panel.

The factory test mode is the most accurate way to test the turbidity sensor circuit, which contains the control module, wiring, and turbidity sensor. Factory test mode will test the thermistor (used for automatic temperature control) that is contained in the turbidity sensor and will test the transmitter that is contained in the turbidity sensor.

Entering Factory Test Mode

Note: This mode can only be entered within the ﬁ rst 2 minutes after power-up. After 2 minutes, factory test mode is unavailable.

Disconnect power from dishwasher. Wait 10 seconds and connect power to dishwasher. Press the Normal and Cookware ("Up" and "Down" on Top Control Models) keypads simultaneously for 3 seconds. (This step must be performed within 2 minutes of power-up.) The control will step through the test cycle for the preset amount of time. Press Delay/Hours to advance to the next step.

TEST CYCLE

1. All LEDs illuminate for 10 seconds.

2. Vent fan energizes for 5 seconds, then the active vent closes.

3. Detergent module is activated. Water valve energizes for 60 seconds.

4. Main pump is energized. Water valve continues ﬁ lling for an additional 10 seconds.

5. Heater is energized and main pump continues to run for an additional 60 seconds.

6. Dishwasher pauses for 40 seconds. During this time the turbidity sensor, control module board, and membrane keypad are being calibrated.

a. The control module will beep continuously and the lock icon LED will light if:

1) The temperature sensor check does not fall between the limits (42°F to 199°F).

2) The control receives an analog signal outside the expected range for the turbidity sensor.

3) The EEPROM was not read correctly.

7. Drain pump energizes for 75 seconds.

8. The detergent module is energized for 60 seconds and the water valve is energized for 70 seconds.

9. The heater and main pump are energized for 60 minutes. (Press DELAY/START DELAY/HOURS on some models to advance to the next step before control times out.)

10. Active vent opens, drain pump is energized for 75 seconds, then active vent closes.

Note: If the calibration test fails, check the following:

• Make certain the dishwasher is not located on a non-insulated outer wall where the temperature at the turbidity sensor may be below 42°F.

• The turbidity sensor may be dirty. Run a rinse only cycle with one cup vinegar or use citric acid crystals (WD35X151) to clean the sensor.
