Troubleshooting
If you encounter any issues, please refer to the following common problems and solutions:
- No Mist: Ensure the humidifier is plugged in, powered on, and the water tank has sufficient water. Check if the mist nozzle is correctly positioned.
- White Powder/Dust: This is typically caused by minerals in hard tap water. Use filtered or distilled water to minimize this issue.
- Leaking: Ensure the water tank is properly seated and the top cover is securely closed. Do not overfill the tank beyond the MAX line.
- Unusual Noise: Check if the humidifier is on a flat surface. Ensure there are no foreign objects in the water tank or mist outlet.
