If your Xiaomi Smart Blender display lights up but doesn't work, please refer to the following steps to troubleshoot the issue:
1. Check whether you press the LED knob after selecting a certain mode. Confirm the function and restart the blender;
2. Check whether the lid is properly attached to the glass jar;
3. If the water is insufficient in the glass jar, the overheating protection function will be triggered and stop working. Please add some water and restart blending after the device is cooled down;
4. Turn off the blender and unplug the power supply if the blender makes error alerts. Then plug the power supply after a few minutes and try again.
If none of the above steps resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
