I. e-1 sensor is broken:1.It is possible that the sensor is broken, including leads, plugs and sockets, etc. 2. The weather is too cold and the sensor resistance is too high.

Causing the electric pressure cooker to display the code; The processing method can connect a 100K resistor in parallel at both ends of the sensor.

II. E-2 Sensor short circuit: Sensor short circuit fault is rare. Generally, it can only be replaced with a new one (the sensor is 100K at room temperature of 25 degrees).

III. E-3 Overtemperature: It is common that the bottom of the pot is too dirty and the temperature is too high.

4. E-4 Pressure switch is out of order: 1. Pressure switch is oxidized due to electric shock and moisture. 2. If the pressure is lower than 0.04MP, start the control. In the first case, handle the oxidation point.

Just clean; In the second case, you have to adjust the pressure switch as follows:

Method for adjust pressure switch of electric pressure cooker

There are two methods, 1. There is a pressure gauge at hand: add an appropriate amount of water to the pot, cover the pot and boil it, remove the pressure relief valve and put on the pressure gauge, and wait until the reading of the meter rises to.

Adjust the pressure switch to just turn it off when it is 0.068MP; Fix the adjusting screw with glue. 2. If you don't have a pressure gauge at hand, don't remove the pressure relief valve and put the pressure first.

Adjust the pressure to the maximum, and when the pressure relief valve just starts to leak, immediately adjust the pressure switch to make it jump, and then turn it clockwise a little more. Remember to be sure

Fix the adjusting screw with glue.

Is this okay?
