What to do if the Xiaomi Smart Evaporative Humidifier fails to work when pressing the buttons?

For your reference, here are the methods below for troubleshooting:
1. Check whether the child lock function is turned on in the Mi Home/Xiaomi Home APP. After turning on the child lock, press any button and the prompt tone will beep twice and the light will flash twice, but there will be no response;
2. Check whether the humidifier is powered on and turned on normally;
3. Unplug and replug the power adapter and try again.
If the above methods are not effective, please contact the after-sales service center for repair.
