The indicator e2 of the rice cooker is a fault, which is usually related to the control circuit of the rice cooker. Under normal circumstances, the rice cooker will automatically stop working after e2 failure, and the failure code will be displayed on the LED display screen. The meaning of e2 fault code may vary with different brands and models, but usually, this fault code indicates that there is something wrong with the control circuit of the rice cooker.

Specifically, the possible reasons include the following aspects:

1. Program control chip failure. The program control chip of rice cooker is an important part of the control circuit. If there is something wrong with the chip, e2 will fail.

2. The temperature controller is damaged. Thermostat is a device to control the temperature of rice cooker. If there is a fault or damage, it will also cause the rice cooker to prompt e2 error.

3. The safety tube is burnt out. Safety tube is the protective device of control circuit. If the safety tube is burnt out or overloaded, it will lead to the failure of the rice cooker e2.

4. Field effect tube failure. Field effect transistor in rice cooker plays an important role in shortening the working time of control circuit. If the field effect transistor fails, it may also lead to e2 failure.

In case of e2 failure, consumers can try the following adjustment methods: 1) Try to use the reset/reset option of the rice cooker; 2) Put the rice cooker in the corresponding position to ensure that the plug of the rice cooker is effectively connected with the power socket; 3) Remove the safety cover of the rice cooker, and check whether the internal components work normally, such as abnormal operation of the motor or loose accessories.

If the above adjustment methods can't solve the problem, it is suggested to contact professional maintenance personnel to solve the e2 fault problem, so as to ensure the safety and normal work of the rice cooker.
