What to do if the Xiaomi Smart Evaporative Humidifier has a loud running noise?

For this issue, you can refer to the following methods for troubleshooting:
1. When the humidifier is turned on for the first time, the water pump will be empty for a short time, making abnormal noises. This is normal and will return to normal after running for about 3 minutes;
2. Check whether there are foreign objects in the water tank;
3. When water is about to run out, the water pump can also make empty pumping sounds or the sounds of filter elements falling into the water. Please add water to the water tank in time;
4. It can be that your filter element is not installed in place. Please try to reinstall the filter element;
5. Check whether the filter element is dirty, clean the filter element;
6. Check whether the water hole on the filter element is blocked, clean the water hole.
If the above methods are not effective, please contact the after-sales service center for inspection and repair.
Note:
The water level sensor, water level float ball and filter element of the humidifier will make a slight sound due to the movement of the machine, which is normal.
