| EXPLANATION AND RECOMMENDED PROCEDURE | ||
|
|
| ||
|
| SERIAL COMMUNICATION ERROR | ||
|
|
| ||
|
| Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) | ||
|
| cannot be sent correctly. | ||
F/11 |
| |||
Possible Causes / Procedure | ||||
|
| 1. | Unplug washer or disconnect power. | |
|
| 2. | Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU). | |
|
| 3. | Check the drive system for any worn or failed components. | |
|
| 4. | Plug in washer or reconnect power. | |
|
| 5. | Verify CCU operation by running a Diagnostic test or any cycle. | |
|
| 6. | Check the MCU by looking for operations of the drive motor. | |
|
| 7. | Check the drive motor for powered rotations. | |
|
| 8. | Check that the serial harness at the MCU is not mounted upside down. The wires should | |
|
|
| be to the left when facing the MCU connectors. | |
|
|
| ||
|
| DISPENSER CIRCUIT ERROR | ||
|
|
| ||
F/13 | If the dispenser motor is not able to be driven to its proper position. | |||
|
| |||
|
| Possible Causes / Procedure | ||
|
| 1. | Unplug washer or disconnect power. | |
|
| 2. | Check mechanical linkage from dispenser motor to the top of the dispenser. | |
|
| 3. | Check wire harness connections to the dispenser motor and Central Control Unit (CCU). | |
|
| 4. | Check dispenser motor for powered rotations. | |
|
|
| ||
|
| EEPROM ERROR | ||
|
|
| ||
|
| The Central Control Unit (CCU) receives its data from an EEPROM onboard the CCU. If there | ||
F/14 |
| is an error reading this data it will cause this error. | ||
|
|
| ||
| Possible Causes / Procedure | |||
|
| |||
|
| • A power glitch may cause this error. | ||
|
| 1. | Unplug washer or disconnect power for two minutes. | |
|
| 2. | Verify CCU operation by running a Diagnostic test or any cycle. | |
|
|
| ||
|
| MOTOR CONTROL UNIT (MCU) ERROR | ||
|
|
| ||
|
| If the MCU detects multiple resets or errors during a wash cycle it will go into this error mode. | ||
|
|
| ||
F/15 | Possible Causes / Procedure | |||
1. Unplug washer or disconnect power. | ||||
|
| |||
|
| 2. Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU). | ||
|
| 3. | Check drive belt. | |
|
| 4. Plug in washer or reconnect power. | ||
|
| 5. Check the MCU by looking for operations of the drive motor. | ||
|
| 6. Check the drive motor for powered rotations. | ||
