FOR SERVICE TECHNICIAN'S USE ONLY 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 3000 V. It takes as little as 10 V 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.

DO NOT REMOVE OR DESTROY 11 FOR SERVICE TECHNICIAN'S USE ONLY TEST PROCEDURES IMPORTANT: The following procedures may require the use of needle probes to measure voltage. Failure to use needle probes will damage the connectors. To ease the process of measuring voltage and resistance, test points for each pin are accessible through the slots in the plastic beneath each ACU connector. To properly check voltage, complete the following steps: 1. Unplug washer or disconnect power. 2. Attach voltage measurement equipment to proper connectors. 3. Plug in washer or reconnect power and verify voltage reading. 4. Always unplug washer or disconnect power after completing voltage measurements. TEST #1: ACU Power Check This test checks for incoming and outgoing power to and from Appliance Control Unit (ACU). This test assumes that proper voltage is present at the outlet. 1. Unplug washer or disconnect power. 2. Remove top panel to access the machine electronics. 3. Visually check that all connections to the interference filter (IF) are securely connected. See Figure 2. 4. Visually check that all connections to the ACU are fully inserted. See Figure 3, page 13. 5. If both visual checks pass, go to step 6. 6. Plug in washer or reconnect power. 7. With a voltmeter set to AC, check for line voltage at the input of the interference filter. See Figure 2. If line voltage is present, go to step 8. If line voltage is not present, verify the continuity of the power cord. If it fails the continuity check, replace the power cord. 8. With a voltmeter set to AC, check for line voltage at the output of the interference filter. See Figure 2. If line voltage is present, go to step 9. If line voltage is not present, replace the interference filter. 9. With a voltmeter set to AC, check for input line voltage to the ACU across pins 1 and 2 of connector J2 AC In (IF filter). See Figure 3, page 13. If line voltage is present, go to step 10. If line voltage is not present, check harnesses and connections between the filter and the ACU. Visually inspect inside connector housing for bent or damaged terminals. Repair as necessary. 10. Service LED/DC Supply The ACU is equipped with a status LED. This LED indicates the health of the ACU. After the ACU is plugged in, the LED will blink rapidly for a few seconds, then will blink slowly (0.5s on, 0.5s off). This LED indicates the functionality of the microcontroller and power supply: If the LED is not lit, there is not 5 V DC supply to the microcontroller. Replace the ACU. If the LED is not blinking slowly within 30 seconds of being powered up, the microcontroller is not responding. Replace the ACU. If the LED is blinking slowly (0.5s on, 0.5s off) during washer operation, the ACU is probably OK and the problem is elsewhere. Check HMI input voltage: With the back panel removed, verify that there is 5 V between pins 2 and 4 at J19. If there is 5 V, go to step 11. If there is not 5 V, disconnect J19 and check for 12.7 V between pin 1 and pin 4. If there is not 12.7 V, replace the ACU. 11. Unplug washer or disconnect power. 12.

If there is no continuity, replace the lower harness and retest. 6. To test either the detergent or fabric softener level sensor, disconnect the appropriate level sensor connector on top of the bulk backer assembly. Using an ohmmeter, connect leads across pins 1 and 2, or 3 and 4 of the connector. With the bulk tank removed, the sensor should read open. 7. While watching the ohmmeter, place a magnet above the appropriate sensor cavity. The magnet should close the sensor (less than 3 ). If the resistance still reads open, replace the detergent level sensor, otherwise continue to step 8. 8. If the preceding steps did not correct the problem, replace the ACU. a. Unplug washer or disconnect power. b. Replace the ACU. c. Reassemble all parts and panels. d. Perform the "Quick Diagnostic Test" to verify repair. Detergent Level Connector Fabric Soft. Level Connector Detergent Pump Fabric Soft. Pump TEST #12: Vent Baffle Solenoid (on some models) This test is performed if the vent fan does not activate. 1. Check rear vent for obstruction that could prevent the fan from opening. 2. Check the vent baffle solenoid and electrical connections by performing the "Quick Diagnostic Test". The following procedures assume that this step was unsuccessful. 3. Unplug washer or disconnect power. 4. Remove the top panel to access the machine electronics. 5. Visually check that connector J9 is inserted all the way into the ACU (refer to Figure 3, page 13). Also check that the solenoid harness is securely connected to the solenoid. If visual check passes, go to step 6. If connector is not inserted properly, reconnect J9 and repeat step 2. 6. With an ohmmeter, measure the resistance across the two solenoid terminals. Resistance should be less than 20 M. If the resistance is infinite (open), replace the solenoid. 7. With an ohmmeter, measure the resistance across the two fan terminals. Resistance should be less than 10 M. If the resistance is infinite (open), replace the vent fan assembly. If the resistance is in the correct range, go to step 8. 8. If the preceding steps did not correct the problem, replace the ACU. a. Unplug washer or disconnect power. b. Replace the ACU. c. Reassemble all parts and panels. d. Plug in washer or reconnect power and perform the "Quick Diagnostic Test" to verify repair. Fabric Soft. Level Sensor Detergent Level Sensor Figure 13 - Drawer Bulk Dispenser Components DO NOT REMOVE OR DESTROY 23 FOR SERVICE TECHNICIAN'S USE ONLY TEST #13: Dry Blower Motor (on some models) This test is performed if the blower fan does not activate. 1. Check the dry blower motor and electrical connections by performing the "Quick Diagnostic Test". The following procedures assume that this step was unsuccessful. 2. Unplug washer or disconnect power. 3. Remove the top panel to access the machine electronics. 4. Visually check that connector J12 is inserted all the way into the ACU (refer to Figure 3, page 13). Also check that the blower motor harness is securely connected to the motor. If visual check passes, go to step 5. If connector is not inserted properly, reconnect J12 and repeat step 1. 5. With an ohmmeter, check harness for continuity between the blower motor and the ACU. If there is continuity, go to step 6. If there is no continuity, replace the upper machine harness and repeat step 1. 6. With an ohmmeter, measure the resistance across the two blower motor terminals. Resistance should be 9-11 . If the resistance is 9-11 go to step 7. If the resistance is much less or much greater than 9-11 , replace the Heater Channel Assembly. NOTE: The blower motor cannot be replaced separately from the Heater Channel Assembly. 7. Remove the Heater Channel Assembly. 8. Confirm that the blower wheel is not obstructed and turns freely. If the blower wheel is obstructed, remove debris and re-assemble to washer. If the blower wheel is not obstructed but does not turn freely, replace the Heater Channel Assembly. NOTE: The blower motor cannot be replaced separately from the Heater Channel Assembly. If the blower wheel turns freely, replace the ACU. 9. Reassemble all parts and panels. 10. Plug in washer or reconnect power and perform the "Quick Diagnostic Test" to verify repair.
