| 3 | - Is the pressure switch hose bent? | |
| the water supply is stopped. | - Check the operation of the water level switch. | |
|
| ||
|
|
| ï If above points are not found, the PCB assembly is out of order. |
|
|
| Replace it. |
|
|
|

| 4 | The drum does not rotate during | (Rotor winding, stator winding, generator) |
| washing. | - Is the motor protector normal? | |
|
| ||
|
|
| ï If above points are not found, the PCB assembly is out of order. |
|
|
| Replace it. |
| 5 | The drum rotates by one direction | - The PCB assembly is out of order. Replace it. |
| during washing. (The drum rotates | ||
|
| to one direction for SPIN.) | (Inversion relay open trouble) |
|
|
| |
|
|
|
|

| |
|
|
| (Little noise may be generated during the |
|
|
| <When the leak breaker and current breaker is installed separately> |
|
|
| - When the leak breaker is down, check and make the earth of the outlet. |
|
| Leak breaker or current/leak | - When the current is down, the current is leaked. |
| 9 | <Is the breaker down when the leak/current breaker is combined?> | |
| breaker is down during washing. | - Check the rated capacity of the current and leak breaker. | |
|
| ||
|
|
| The current breaker may be down due to the lack of the current when the |
|
|
| wash machine and other apparatus are used. |
|
|
| In this case, execute the cold water wash to check whether the current capacity is lack. |
