1, E1 sensor disconnection: if the United States of America's electric pressure cooker displays the E1 fault, presumably, the sensor has a disconnection, which includes the lead, the plug socket and so on. If the weather temperature is too low, the sensor resistance value is too high, easy to cause the electric pressure cooker to display the code problem, you can in the sensor at both ends. Position in parallel with a 100K resistor can be.
2, E2 sensor short circuit: sensor short circuit need to replace the new sensor, it is at 25 degrees room temperature, need 100 resistance.
3, E4 pressure switch failure: in the United States of America electric pressure cooker operation, if the E4 code, it may be a switch failure, the pressure switch is subject to water vapor oxidation rust. It is also possible that when the pressure is lower than 0.04MP, it will also automatically lose control, and need to replace a new switch.
4, C0 battery dead: C0 is to show that the battery has no power, directly replace the new battery.
5, C1: C1 is the bottom of the thermostat or the corresponding input circuit open circuit, the solution * is to directly replace the bottom of the thermostat, pay attention to the same model, or overhaul the corresponding input circuit.
