1.E- 1 The sensor is broken: 1. It is possible that the sensor is broken, including leads, plugs and sockets. 2. The weather is too cold and the sensor resistance is too high.
Make the electric pressure cooker display the code; The processing method can connect a 100K resistor in parallel at both ends of the sensor.
Two. E-2 sensor short circuit: sensor short circuit fault is rare. Generally, only new ones can be replaced (the sensor is 100K at room temperature of 25 degrees).
Three. E-3 overtemperature: It is common that the bottom of the pot is too dirty and the temperature is too high.
Four. E-4 pressure switch failure.
