If the Xiaomi High-speed Ionic Hair Dryer does not work, you can refer to the following steps to troubleshoot:
1. Check whether the power supply is normal, whether there is a power outage, the line fuse is blown, the plug is not plugged in or loose during the use of the hair dryer;
2. Check whether the line voltage at home is too low (below 187V). Low voltage will cause the hair dryer to stop working;
3. Turn off the power and unplug the plug to check whether there are foreign objects entering the air inlet and outlet. Foreign objects entering will cause the hair dryer to stop working;
4. If the hair dryer does not work during operation, it can be due to blockage of the air inlet or outlet of the hair dryer, causing it to overheat. When the hair dryer is overheated, it will automatically shut down for protection. After standing for 5 minutes, it can be restarted for use.
