In case of this fault, first measure the sensor (that is, the sensor in the center of the heating plate) to see if there is an open circuit or an open circuit. If it is normal, disassemble the control panel to see if it is damp, which may lead to an error message. In addition, observe whether the solder joints of the motherboard circuit will fall off and get an error message. ? If necessary, you can seek professional maintenance personnel to deal with it.
Electric pressure cooker is an upgraded product of traditional pressure cooker and rice cooker. It combines the advantages of pressure cooker and rice cooker, and adopts new technologies and structures such as elastic pressure control, dynamic sealing, external rotating cover, electric switch with adjustable displacement, fully sealed cooking, continuous pressure adjustment, etc., which completely solves the safety problem of pressure cooker and relieves the potential safety hazard that ordinary pressure cookers have plagued consumers for many years.
Electric pressure cooker is a kind of kitchen cooker. The pressure cooker exerts pressure on water through the physical phenomenon that the boiling point of liquid will rise under higher air pressure, so that the water can reach a higher temperature without boiling, thus accelerating the efficiency of stewing food.
