F10
Motor Control Unit (MCU) heat
sink thermal trip
F11
Serial communication error
F13
Dispenser circuit error
F14
EEPROM error
Potential Causes
• Check the drain hose and make sure it is not plugged or
kinked
• Check Wire Harness connections to the Drain Pump,
Pressure Switch, and Central Control Unit (CCU)
• Check / Clean Drain Pump Filter of foreign objects
• Check for Drain Pump Failure
• Check the Inlet Valve for proper shut off
• Check the Pressure switch for proper operation
Replace failed component.
If the thermal protector on the MCU heat sink gets too
hot, it will open the thermal protector on the heat sink
which will stop motor functions and an F10 will be
displayed.
Potential Causes
• Check for Proper Installation, verify the unit is not
located near a source of heat and has proper ventilation.
• 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 Motor
Replace failed component.
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
Replace failed component.
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
Replace failed component.
The Central Control Unit (CCU) receives it's data from an
