|
| MOTOR CONTROL UNIT ERROR | |
|
|
| |
|
| The main control has detected a short in the Motor Control Unit. If a failure occurs during | |
|
| ||
F/07 |
|
| |
| Possible Causes / Procedure | ||
|
| 1. | Unplug washer or disconnect power. |
|
| 2. | Check wire harness connections between the drive motor and the Motor Control Unit |
|
|
| (MCU), and between the MCU and the Central Control Unit (CCU). |
|
| 3. | Plug in washer or reconnect power. |
|
| 4. | Check the MCU by looking for operations of the drive motor. |
|
| 5. | Check the drive motor for powered rotations. |
|
|
| |
|
| 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 remains locked and the drain pump | |
|
| runs constantly, even if PAUSE/CANCEL is pressed twice and the display is cleared. Turn off | |
|
| hot and cold water faucets and unplug the unit before servicing. | |
F/09 |
|
|
|
| Possible Causes / Procedure | ||
|
| ||
|
| 1. | Check the drain hose and make sure it is not plugged or kinked. |
|
| 2. | Unplug washer or disconnect power. |
|
| 3. | Check wire harness connections to the drain pump, pressure switch, and Central Control |
|
|
| Unit (CCU). |
|
| 4. | Check/clean drain pump filter of foreign objects. |
|
| 5. | Check for drain pump failure. |
|
| 6. | Check the inlet valve for proper shut off. |
|
| 7. | Check the pressure switch for proper operation. |

|
| 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. | |
F/10 |
| ||
Possible Causes / Procedure | |||
|
| 1. | Check for proper installation, verify the unit is not located near a source of heat and has |
|
|
| proper ventilation. |
|
| 2. | Unplug washer or disconnect power. |
|
| 3. | Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU). |
|
| 4. | Check the drive system for any worn or failed components. |
|
| 5. | Plug in washer or reconnect power. |
|
| 6. | Check the MCU by looking for operations of the drive motor. |
|
| 7. | Check the drive motor for powered rotations. |
