1. The general e5 fault code indicates that the temperature sensor of the upper cover of the rice cooker is damaged. 2. In another case, if there is an open circuit in the connecting wire of the rice cooker, e5 fault will also be displayed. 3. In addition, the temperature sensor of the bottom sensor is open, and the e5 fault code may be displayed. 4. Maintenance can be carried out according to the fault code description in the product manual. Suggested solution: 1. First, you need to unscrew the screw at the back of the rice cooker with a screwdriver and take out the cover at the back, so that you can see the connection line between the internal spring and the temperature sensing probe. 2. Then, it is necessary to remove the sealing ring on the inside of the cover and unscrew the screws on the inside with a screwdriver. 3. Gently pry open the periphery with a screwdriver and slowly open the lid to expose the mechanical parts and temperature sensing elements inside the rice cooker. 4. Then you can see where the sensor connection line is broken. Cut the broken ends into copper wires with scissors, connect them together, and then stick them with black tape. 5. Finally, reinstall the rice cooker and plug in the electric tester to see if the fault code of e5 still appears. If it does not appear, it has been fixed. If the e5 code still appears, it is recommended to contact the after-sales service and send it directly to the after-sales service for testing.
