FAILURE/ERROR DISPLAY CODES DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE NO WATER DETECTED ENTERING MACHINE OR PRESSURE SWITCH TRIP NOT DETECTED If after 30 seconds the control does not detect water entering machine, the valves will be turned off and the error code will be displayed. If the control has turned the water valves on, and after 8 minutes, the flow sensor has de- tected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off, and the error code will flash.
DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE LONG DRAIN If the drain time exceeds eight minutes, the water valves are turned off and “F/02 ” is flashed. Press PAUSE/CANCEL two times to clear the display. NOTE: After four minutes the “Sud” error will be displayed, then four minutes later the “F/02 ” error code will be displayed..
DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE MOTOR CONTROL UNIT ERROR The main control has detected a short in the Motor Control Unit. If a failure occurs during high-speed spin, the door will be unlocked after three minutes. F/07 Possible Causes / Procedure 1.
DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE SERIAL COMMUNICATION ERROR Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly. F/11 Possible Causes / Procedure 1. Unplug washer or disconnect power. 2. Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU). 3.
DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE CCU / TOUCHPAD / LED ASSEMBLY ERROR F/21 F/22 This error occurs if the touchpad/LED assembly is not able to transmit/receive data to/from the central control unit (CCU). Possible Causes / Procedure 1. Check the touchpad/LED assembly by selecting different cycles and changing the modifiers and options available to confirm the touchpad/LED is responding.
DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE SUDS LOCK (OVERDOSE OF DETERGENT DETECTED DURING THE WASH CYCLE) The Motor Control Unit senses a suds lock condition by analyzing the current draw on the drive motor. If “Sud ”is displayed a potential Suds Lock is detected. This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.
