Step 1: Check the power connection.
First of all, you need to check whether the power connection of Xiaomi toilet lid is normal. If there is a problem with the power connection, the toilet lid may not open. You can check whether the power plug is inserted into the socket correctly and make sure that the power cord is not damaged or worn.
Step 2: Replace the battery.
Secondly, you can try to replace the battery. Millet toilet covers usually use batteries as power supply. If the battery is low, expired or has other problems, the toilet lid may not open. Before replacing the battery, it is necessary to confirm the battery model used in Xiaomi toilet cover, and then select the corresponding battery model to replace it.
Step 3: Reset the electronic system.
Finally, if the above two steps can't solve the problem, you can try to reset the electronic system of Xiaomi toilet cover. Specifically, press and hold the toilet lid button 10 second while ensuring that the toilet lid is closed, and then release the button. This can reset the electronic system of the toilet lid and sometimes solve the problem that it can't be opened.
Generally speaking, the problem that the millet toilet lid can't be opened can be solved by the above three methods. If you still can't solve the problem after trying the above methods, I suggest you contact Xiaomi after-sales service center for help.
