9. Troubleshooting
If you encounter any issues with your humidifier, please refer to the following common problems and solutions:
- No Mist Output: Ensure the water tank is filled and correctly seated. Check if the power cord is securely plugged in. If the unit has been running for a while, check for mineral buildup and clean the unit.
- Leaking Water: Verify that the water tank is properly aligned and sealed on the base. Ensure the humidifier is placed on a flat, level surface. Avoid overfilling the water tank beyond the MAX line.
- Unusual Noise: A slight trickling sound of water is normal. If the noise is excessive, ensure the unit is on a stable surface and not vibrating against other objects. Check for any obstructions in the fan or mist outlet.
- White Dust: This is typically caused by hard water. Consider using distilled or demineralized water to reduce white dust accumulation. Regular cleaning also helps.
- Humidifier Not Reaching Desired Humidity: Ensure the room size is within the humidifier's coverage area (up to 500 sq.ft.). Close windows and doors to prevent humidity from escaping. Increase the mist output setting.
