Filtration System and Maintenance

Drying Rinse aid is essential

Your dishwasher has a ltration system that

ef ciently removes food particles from the

wash water.

The lter system consists of three parts:

Coarse lter

a ne lter plate, a coarse lter, and a

lower lter.

Fine lter

IMPORTANT: To avoid damage to

dishwasher, do not operate your

dishwasher without lters properly

Lower lter

installed. Be sure lower lter is securely

in place and upper lter assembly is locked

into place. If the coarse lter turns freely,

it is not locked into place.

The lters may need to be cleaned when:
I Visible objects or soils are on ne lter plate.
I Dishes feel gritty to the touch.
See the "Filtration System" section in the full User Instructions for complete removal and maintenance schedule.
IMPORTANT: Do not use a wire brush or a scouring pad, etc., as they may damage the lters. Rinse lter under running water until soils are removed. If you have hard-to-remove soils or calcium deposits because of hard water, a soft brush may be required.

You must use a drying agent such as a rinse aid for good drying performance. Rinse aid along with the Heated Dry option will provide improved drying and avoid excessive moisture on the dishwasher interior.
Press START every time you add a dish
If anyone opens the door after the dishwasher has started (such as for adding a dish, even during the delay time), the Start button must be pressed again to resume the cycle. Press START and push the door rmly closed.
Adjust Upper Rack
You can raise or lower the upper rack to t all items in either the upper or lower rack. To raise or lower the rack: Empty the rack. Pull the rack out halfway and take notice of the position of the carriage wheel assembly and side rail on each side of the rack. Lift up on the front of the rack while pulling the rack out all the way. The rack will then be completely free of the side rails. Reverse this action to re-engage the rack's carriage wheels onto the rails in the higher or lower position desired. NOTE: The upper rack must be level.

Cleaning the Exterior
Clean the exterior of the dishwasher with only a soft, damp cloth and mild detergent. Avoid using abrasive cleaning products on the exterior of the dishwasher.
Cleaning and Maintaining the Interior
Many detergents may leave white spots or a white residue on dishware and on the interior of the dishwasher. Over time this residue can become unsightly and could affect dishwasher performance. Use of a dishwasher cleaning product such as affresh® Dishwasher Cleaner can help to remove the residue. Monthly use of affresh® Dishwasher Cleaner is recommended to help maintain the dishwasher. Follow package directions.
NOTE: The manufacturer recommends the use of high-quality premeasured detergent tablets or packs and the use of rinse aid for dishwasher cleaning and daily care.

If you have a drain air gap, check and clean it if the dishwasher isn't draining well.
To Reduce Risk of Property Damage During Vacation or Extended Time Without Use:
I When you will not be using the dishwasher during the summer months, turn off the water and power supply to the dishwasher.
I Make sure the water supply lines are protected against freezing conditions. Ice formations in the supply lines can increase water pressure and cause damage to your dishwasher or home. Damage from freezing is not covered by the warranty.
I When storing your dishwasher in the winter, avoid water damage by having your dishwasher winterized by authorized service personnel.

WARNING

Electrical Shock Hazard Disconnect power before servicing.
Replace all parts and panels before operating. Failure to do so can result in death or electrical shock.

Voltage Measurement Safety Information
When performing live voltage measurements, you must do the following: Verify the controls are in the off position so that the appliance does not start when energized. Allow enough space to perform the voltage measurements without obstructions. Keep other people a safe distance away from the appliance to prevent potential injury. Always use the proper testing equipment. After voltage measurements, always disconnect power before servicing.
IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics ESD problems are present everywhere. Most people begin to feel an ESD discharge at approximately 3000V. It takes as little as 10V to destroy, damage, or weaken the main control assembly. The new main control assembly may appear to work well after repair is finished, but a malfunction may occur at a later date due to ESD stress. Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted
metal in the appliance
-OR-
Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.
Before removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted metal in the appliance.
Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.
When repackaging main control assembly in anti-static bag, observe above instructions.

IMPORTANT SAFETY NOTICE -- "For Technicians only" This service data sheet is intended for use by persons having electrical, electronic, and mechanical experience and knowledge at a level generally considered acceptable in the appliance repair trade. Any attempt to repair a major appliance may result in personal injury and property damage. The manufacturer or seller cannot be responsible, nor assume any liability for injury or damage of any kind arising from the use of this data sheet.

TESTING

For Service Technician Use Only

DANGER
Electrical Shock Hazard Only authorized technicians should perform diagnostic voltage measurements. After performing voltage measurements, disconnect power before servicing. Failure to follow these instructions can result in death or electrical shock.
General Theory of Operation
Refer to Wiring Diagram on page 3-3.
Neutral and L1 (AC voltage) enters the Control Board at CON1, pins 1 & 2 respectively. AC is converted to DC voltage at the Low Volts Power Supply (LVPS). Supplies include +12 and +5 VDC, and DC GND (REF). These low voltage supplies are used to provide power to the microprocessors and board components, power the sensors and energize the AC relays. The 12 VDC is vital to the operation of the dishwasher. This supply is necessary to operate all 120 VAC loads in the dishwasher, whether they are connected to a relay or controlled by TRIACs. 12 VDC is generated by the power supply and flows through the door switch--when closed--to be available to the heater relay, wash motor relays, and the drain pump relay. A relay coil becomes energized when the control closes the LV drive circuit for a specific relay completing 12V pathway, which in turn closes the relay switch providing AC to the load.

Power Check
This test checks for incoming and outgoing power to and from the control board. This test assumes that proper voltages is present at the outlet or direct connect cable.
Test Procedure
1. Unplug dishwasher or disconnect power.
2. Remove access panel.
3. Remove terminal box cover.
4. With a voltmeter set to AC, insert black probe inside white wire screw nut (N) and insert red probe inside black wire screw nut (L1).
5. Plug in dishwasher or reconnect power. ¾¾ If 120 VAC is present, unplug dishwasher or disconnect power and proceed to step 6. ¾¾ If 120 VAC is not present, have customer correct power problem at outlet or breaker.
6. Remove the control board cover.
7. Locate connector CON 1.
8. With a voltmeter set to AC, connect leads across the two pins ("N" and "L") on CON 1.
9. Plug in dishwasher or reconnect power. ¾¾ If 120 VAC is present, go to step 10. ¾¾ If 120 VAC is not present, check for open connection between terminal block and control. Repair as needed.
10. Verify DC Supplies
· 5 VDC is used to power IC's and micro-processors on the circuit board as well as provide power to the sensors. ¾¾ If 5 VDC were missing, the control and Turbidity Sensor would not function. To verify 5V ± 5%, with a voltmeter set to DC, connect the black lead to CN4-2 (DC GND) and the red lead to CN3-1 (+5V).
· 12 VDC is used to actuate the heater, drain and wash pump relays as well as the dispenser and water inlet valve. ¾¾ If 12 VDC was missing, the heater, pumps, and all other loads would not turn on. To verify 12V ± 5%, with a voltmeter set to DC, connect the red lead to CN6-1 (12V) and black lead to CN4-2 (DC GND).

Troubleshooting Missing DC Supplies: Refer to the wiring diagram on page 3-4 when troubleshooting the DC supplies. If 5 VDC or 12 VDC is missing on the control, unplug dishwasher or disconnect power, and then disconnect all components/loads from the control relying on the missing or loaded supply. Plug in dishwasher or reconnect power and check if the DC supply has returned.
¾¾ If not, replace the control.
¾¾ If it has, turn off dishwasher and reconnect one connector at a time until the component loading down that supply has been identified.
11. Unplug dishwasher or disconnect power.
12. Reassemble all parts and panels.

DANGER
Electrical Shock Hazard Only authorized technicians should perform diagnostic voltage measurements. After performing voltage measurements, disconnect power before servicing. Failure to follow these instructions can result in death or electrical shock.
Door Switch Circuit
Perform the following checks if the dishwasher does not detect the door open or closed. This test will check the wiring to the door switch and the door switch itself. The following items are part of the door switch circuit. Harness/Connection Door Switch/Latch Assembly Control Board
Test Procedure
1. Check for improper installation of the dishwasher or leveling. Check door latch mechanism for obstructions or binding. Verify door seal is seated properly. Check for interference between dish racks and door. Repair as necessary.
2. Unplug dishwasher or disconnect power. 3. Remove the access panel and the control board cover.
Remove or fold back plastic cover over door switch.

4. Check door switch contacts and all connections in the door switch circuit. Visually check that the CN6 connector on the control and the door latch terminals are securely installed. ¾¾ If visual check passes, go to step 5. ¾¾ If any of the connectors are not inserted properly, reconnect and retest door latch/switch.
5. Disconnect connector CN6 from the control board.
6. Using an ohmmeter, measure across CN6, pins 1 and 3 (12V & IS respectively) with the door closed, strike completely in latch mechanism (switch closed). ¾¾ If 3 ohms or less is measured, proceed to step 7. ¾¾ If high resistance is measured when door is closed, check for loose connections and repair as needed.
7. Using an ohmmeter, measure across CN6, pins 1 and 3 (12V & IS respectively) with the door open, strike removed from latch mechanism (switch open). ¾¾ If reading is infinite, go to step 8. ¾¾ If reading shows continuity, or door switch is damaged, replace door switch and retest.
8. Set voltmeter to DC and connect red lead to CN6, pin 1 (12V) and black lead to CN4, pin 2 (DC GND) on the control board.
9. Plug in dishwasher or reconnect power and with door open, verify that 12 VDC is present across CN6-1 and CN42. ¾¾ If 12 VDC is not present, replace the control and retest. ¾¾ If 12 VDC is present, proceed to step 10.
10. Reconnect CN6 & CN4 to control board and perform Diagnostic Cycle to verify operation.
11. Unplug dishwasher or disconnect power.
12. Reassemble all parts and panels.
13. Plug in dishwasher or reconnect power.

Component Testing
TESTING DISHWASHER COMPONENTS FROM THE CONTROL BOARD
Before testing any of the components, perform the following checks:
· The most common cause for misdiagnosed control failure is poor connections. Therefore, disconnecting, inspecting and reconnecting wires will be necessary throughout test procedures.
· All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms-per-volt DC, or greater.
· Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.
· Voltage checks must be made with all connectors attached to the boards.
· Resistance checks must be made with power cord unplugged or power disconnected, and with wiring harness or connectors disconnected from the control.
· The testing procedures in this section may require the use of needle probes to measure voltage. Failure to use needle probes will damage the connectors.

WARNING
Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock.
Pressure Switch
The pressure switch is an overfill safety device mounted on the base located on the right front. A clear plastic tube (the pressure switch hose) runs from the switch to the sump. As the dishwasher tub fills with water, the air pressure in the pressure switch hose increases. Normally, the control board regulates the amount of time the water fill valve remains open. If the water fill valve remains energized, the overfilling of the tub increases the air pressure in the pressure hose causing the pressure switch to close and energize the drain pump.
This test will check the wiring to the pressure switch and the pressure switch itself. The following items are part of the pressure switch circuit. Harness/Connection Pressure Switch Pressure Switch Hose

Test Procedure
1. Unplug dishwasher or disconnect power.
