|
| 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. |

F10 | Motor Control Unit (MCU) heat | If the thermal protector on the MCU heat sink gets too |
| sink thermal trip | 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. |
|
|
|
F11 | 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 |
|
| Replace failed component. |
|
|
|
F13 | 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 |
|
| Replace failed component. |
|
|
|
F14 | EEPROM error | The Central Control Unit (CCU) receives it’s data from an |
