F/06 | Drive Motor Tachometer Error | |
| The control is unable to properly detect motor speed and the machine will shut down. | |
| If a failure occurs during | |
| Potential Causes | |
| • Check wire harness connections between the Drive Motor/Tachometer and the | |
|
| Motor ControlUnit (MCU), and between the MCU and the Central Control Unit |
|
| (CCU) |
| • Check the Drive Motor | |
| • | Check the MCU |
| • Check the Wire Harness | |
F/07 | Motor Control Unit Error | |
| The Central Control Unit has detected a short in the motor control unit. If a failure | |
| occurs during | |
| Potential Causes | |
| • Check wire harness connections between the Drive Motor and the Motor Control | |
|
| Unit (MCU), and between the MCU and the Central Control Unit (CCU) |
| • | Check the MCU |
| • Check the Drive Motor | |
| • Check the Wire Harness | |
|
| |
F/09 | Overflow Condition | |
| If the Overflow contact on the pressure switch is Closed for more than 60 seconds | |
| an Overflow condition will occur. In an Overflow condition, the Door will remain | |
| locked, and the Drain Pump will run constantly, even if PAUSE/CANCEL is pressed | |
| twice and the Display is cleared. Unplug the unit to service. | |
| 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 | |
|
| |
F/10 | Motor Control Unit (MCU) Heat Sink Thermal Trip | |
| 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 “F/10” 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 |
