2, float sealing ring sticky food or damage caused by air leakage: detection of float sealing ring, if sticky food, cleaning can be, if bad, then change the new one.
3, lid leakage: first of all, clean the lid sealing ring to put a good sealing ring, such as gas leakage, then test the sealing ring, lid steel ring and pot liner is damaged, such as bad, then change.
Pressure cooker precautions:
1, not check before use: use, first of all, carefully check whether the vent is smooth, the hole under the seat of the safety valve is not blocked by residual rice particles or other food debris. If the use of the process is blocked by food, the power should be unplugged, forced cooling, clean air holes to continue to use, otherwise the use of food will be sprayed out scalding.
2, the lid is not in place: the handle of the lid must be matched with the pot body of the instruction sticker before you can start cooking food, otherwise the lid is not covered, the pressure can not come up, or the pressure comes up, resulting in the lid popping up, easy to lead to people scalded.
3, unauthorized pressurization: a little understanding of the principle of electric pressure cooker friends open the bottom cover, adjust the pressure switch, do not know the size of the pot pressure is a strict technical parameters, ignoring this scientific design, is equal to their lives joke, private disassembled, change the original structural design caused by the pot burst the serious consequences of human injury, the manufacturer is not responsible for, do not take this risk.
4, overfilled: the use of pressure cooker to put food ingredients, the capacity should not be more than four-fifths of the pot's content area, if it is easy to expand the beans and other food shall not exceed two-thirds of the pot's content area.
5, open the lid in the middle: in the heating process, never open the lid in the middle, so as not to burst out of the food scalding. In the end to confirm the cooling before, do not remove the weight or pressure regulator, lest the spray out of food injury. The lid should be opened only after natural or forced cooling.
