Troubleshooting
Q:Why doesn't the display light up after turning on the power?
A:It's possible that water has entered the circuit board. Air-dry the main body for
24hrs. If it still can't be turned on, please contact customer service via email.
Q:Why is the mist output low?
A:When the ambient humidity exceeds the set value, the machine will
automatically stop spraying mist. However, if the atomizer is damaged, please
contact customer service via email.
Q: Why is the red light flashing?
A: It indicates that there is no water in the tank. Ensure the water tank is filled with
clean, distilled water. If there is water in the tank, check if the water pump has fallen
off or is malfunctioning. Please reinstall it or contact customer service for a replace-
ment. If the pump is working normally, check if the float is dirty and unable to move
freely. Clean the float with a cotton swab.
Q: Why is there unusual noise?
A: There could be too little water or the humidifier may be placed on an unstable surface.
Place the humidifier on a solid and sturdy surface and fill the water tank with water.
Q: Why is there white powder around the humidifier?
A: Tap water contains minerals that can adhere to objects.
We recommend using purified or distilled water to fill the humidifier. Avoid using water
with high mineral content, such as tap water. Clean the water tank regularly and keep
precision instruments away from the humidifier to avoid damage.

Troubleshooting
*If your problem is not listed, please contact Customer Support.
Q: Why is there scale in the water sink or tank?
A: Tap water contains minerals that can adhere to objects. Clean the water sink and
tank regularly
Q: Why does display show an incorrect humidity percentage?
A: Moisture may have built up the humidity sensor. Please dry the sensor with a cloth
or air dry it first.
The humidity sensor will give an improper reading if it is exposed to dust. Avoid
using the humidifier in dusty rooms. Avoid using tap water in the humidifier as this
can increase dust in the air.
Please note that the humidity sensor and hygrometer in the room may have an
error range of 5-10% depending on the sensing method and structure.
If neither of these is the issue, please contact cusstomer service to get
replacement pump via email.
Q: Why is the floor wet or there is water around the humidifier?
A: The humidity may be too high or the humidifier may be placed in a non-ventilated
area, causing the mist to not fully evaporate.
Q: Why is there interference with the TV remote control signal?
A: Keep the humidifier at least 1 meter away from the TV or other objects that emit
radio waves.
Q: Why is the fire on the stove turning red?
A: The composition of tap water can react with the flame, so keep the humidifier
away from the stove.
