(1) The upper cover thermistor is open or short-circuited (usually 100K/25 degrees Celsius). The solution is to replace the upper cover thermistor.
(2) The cover is not closed properly or the trigger switch and its wiring are faulty. The solution is to close the cover normally, and check whether the trigger switch and its wiring are normal, and whether the micro-switch contact can be effectively closed after closing the cover normally.

Extended data:
? The fault code E0 of the pressure cooker indicates that the main sensor at the bottom of the cooker is open or short-circuited.
Cause and elimination of failure:
1, first check whether the terminal plug-in of the temperature sensor is loose or has poor contact.
2. Check whether the temperature sensor is faulty. Measure the resistance value with a multimeter. If it is infinite, it is an open circuit; If it is 0 ohm, it is a short circuit and needs to be replaced with a new product.
3. Check whether the control circuit board is faulty. The control panel cannot receive or send control signals, so it needs to be replaced.
