Serial Communication Error
Communication between the Central Control Unit (CCU) and the Motor Control Unit
(MCU) cannot be sent correctly.
Potential Causes
• Check Wire Harness connections to the MCU, the motor, and Central Control
Unit (CCU)
• Check the Drive system for any worn or failed components
• Check MCU
• Check CCU
• Check Motor
• Check Wire Harness
Dispenser Circuit Error
If the dispenser motor is not able to be driven to it’s proper position.
Potential Causes
• Check mechanical linkage from dispenser motor to the top of the dispenser.
• Check Wire Harness connections to the dispenser motor and Central Control
Unit (CCU)
• Check Dispenser Motor
EEPROM Error
The Central Control Unit (CCU) receives it’s data from an EEPROM onboard the
CCU. If there is an error reading this data it will cause this error.
Potential Causes
• A power glitch may cause this error. Try unplugging the Unit for two minutes to
see if that fixes the error.
• Check CCU.
Motor Control Unit (MCU) Error
If the MCU detects multiple resets or errors during a wash cycle it will go into this
error mode.
Potential Causes
• Check Wire Harness connections to the MCU, the motor, and Central Control
Unit (CCU)
• Check Drive belt
• Check MCU
• Check Motor
• Check Wire Harness
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.
