The failure of E05 in Mijia rice cooker usually means that there is something wrong with the power input. This problem may be caused by overload, voltage fluctuation or instability of the power supply line. To solve this problem, you can try the following steps:

1. Check the power cord-make sure that the socket works normally, the power cord is not damaged, and the plug and socket are firmly connected.

2. Check other electrical appliances-if other electrical appliances run on the same circuit, it may lead to voltage instability. Please ensure that other electrical appliances are not overloaded and operate normally.

3. Voltage regulator-If your power supply fluctuates frequently, please consider adding a voltage regulator.

4. Check the cooked rice-if your rice cooker works for a long time and cooks rice, it may overheat and overload, leading to E05 failure.

If the above steps do not help solve the problem, please consider contacting Xiaomi customer service or related professionals for repair or replacement.
