FAILURE/ERROR DISPLAY CODES Communication of failure codes will be dis- played on the washer console by all cycle lights flashing and standing status lights. DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE Reference Status LEDs chart, page 6-4 Reference Status LEDs chart, page 6-4 EEPROM ERROR A communication error between the Central Control Unit (CCU) and the EEPROM onboard the CCU occurred. Possible Causes/Procedure A power glitch may cause this error. - Unplug washer or disconnect power for two minutes. - Verify CCU operation by running a Diagnostic Test or any cycle. PUMP DRIVE ERROR The pump driver fails to activate. Possible Causes/Procedure Replace CCU board. MAIN RELAYS ERROR One of the main relays is not working properly. Possible Causes/Procedure The relay might be soldered or always open. - Replace CCU board. MOTOR CONTROL UNIT ERROR The Motor Control Unit has internal failure; repeating under or over voltage, or over current conditions. If failure occurs during high-speed spin the door unlocks after 3 minutes. Possible Causes/Procedure 1. Unplug washer or disconnect power. 2. Check wire harness connections between the drive motor and the Motor Control Unit (MCU), and b etween the MCU and the Central Control Unit (CCU). Check the motor and do a continuity test. 3. Plug in washer or reconnect power. 4. Check the MCU by looking for operations of the drive motor. 5. Check the drive motor for powered rotations. 6. Replace MCU board. Reference Status LEDs chart, page 6-4 NO WATER DETECTED ENTERING MACHINE OR PRESSURE SWITCH TRIP NOT DETECTED. The pressure switch is not tripped after 6 minutes. Possible Causes/Procedure If there is no water in the unit: - Make sure that both valves at the water source(s) are turned on all the way. - Check for plugged or kinked inlet hoses or plugged screens in the inlet valves. - Verify inlet valve operation. If there is water in the unit: - Verify drain pump operation. - Verify that the pressure switch hose is in good condition and properly connected to tub and pressure switch. 1. Verify there is not a siphon problem. 2. Press PAUSE/CANCEL twice to clear the display. The machine will drain for 3 minutes before unlocking the door. 3. Unplug washer or disconnect power. 4. Verify wire harness connections to inlet valves, pressure switch, drain pump and Central Control Unit (CCU). 5. Check all hoses for possible leaks. 6. Plug in washer or reconnect power 7. Verify pressure switch operation. 8. Verify CCU operation by running a Diagnostic Test or any cycle. DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE Reference Status LEDs chart, page 6-4 LONG DRAIN If the drain time exceeds 8 minutes the water valves turn off. NOTES: After 4 minutes the "Sd" error will be displayed, then 4 minutes later the "F/21" error code will be displayed. Press PAUSE/CANCEL two times to clear the display. Possible Causes/Procedure 1. Check the drain hose and make sure it is not plugged or kinked. 2. Unplug washer or disconnect power. 3. Check the electrical connections at the pump and make sure the pump is running. 4. Check the drain pump filter for foreign objects. 5. Plug in washer or reconnect power. 6. If the above does not correct the problem, go to step 7. 7. Unplug washer or disconnect power. 8. Replace the pump. Reference Status LEDs chart, page 6-4 Reference Status LEDs chart, page 6-4 Reference Status LEDs chart, page 6-4 DOOR LOCK ERROR After 6 failed attempts to lock the door. Possible Causes/Procedure Door lock mechanism is broken or removed from door. Door switch/lock unit failure. 1. Unplug washer or disconnect power. 2. Check door switch/lock unit. 3. Check the wire harness connections to the door switch/lock unit and Central Control Unit (CCU). HEATER FAILURE If the temperature increase during the first 40 minutes is less than 86°F (30°C). Possible Causes/Procedure 1. Unplug washer or disconnect power. 2. Check connection to water heater. 3. Check resistance of heating element, if present on this model. (abnormal = infinity) 4. Check the water temperature sensor and connection to it. Refer to the Water Temperature Sensor section. WATER TEMPERATURE SENSOR ERROR If the water temperature sensor (NTC) value is out of range (23°F to 217°F [-5°C to 103°C]) during the water-heating step of the WASH cycle. NOTE: To find correct Ohm reading refer to the Water Temperature Sensor section. Possible Causes/Procedure 1. Unplug washer or disconnect power. 2. Check the water temperature sensor and connection to it. 3. Check resistance of heating element, if present on this model. (abnormal = infinity) 4. Refer to the Water Temperature Sensor section. 6-2
