6. Troubleshooting
If you encounter issues with your dehumidifier, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Dehumidifier does not turn on. | No power supply. Power button not pressed. Water tank full or incorrectly inserted. | Check if the power adapter is securely plugged into the unit and the wall outlet. Press the power button firmly. Empty the water tank and ensure it is correctly reinserted. |
