When the electric pressure cooker is used to press food, the exhaust valve should be set in the sealed position after the cover is tightened. If the gear is set on the exhaust gear, there will be continuous exhaust after boiling.
2. Check whether the pressure cooker is tightly covered.
If the pressure cooker is not tightly covered, there will be air leakage in the electric pressure cooker. In this respect, not only novices, but also people who often use it will be careless for a while, resulting in a loose high-pressure pot cover.
3. Check the pressure cooker sealing ring for foreign bodies.
If there are foreign objects on the sealing ring of the pressure cooker, resulting in poor sealing of the pressure cooker, air leakage will also occur. Remove foreign matter from the sealing ring.
4. Check whether the sealing ring of the pressure cooker is deformed.
When the electric pressure cooker is used for a long time, the sealing ring will wear, and the deformation will cause poor sealing and air leakage. Try replacing the sealing ring.
5. Check whether the pot liner and lid are deformed.
If the pot liner and the pot cover are bumped and deformed, the sealing behind the pot cover is not tight, which will also lead to air leakage.
6. The floating valve of the electric pressure cooker leaks oil.
The floating valve of the electric pressure cooker leaks air, so the sealing ring needs to be replaced. If you can't see it or can't replace it, it is recommended to maintain it after sale.
7. Pressure limiting exhaust valve leaks.
The leakage of pressure-limiting exhaust valve is caused by the failure of exhaust pipe, thimble and switch, which needs professional maintenance personnel to check and repair.

Pay attention to cooking with pressure cooker:
One bogey: improper choice
According to the actual needs of the family, choose an electric pressure cooker with appropriate size, complete functions, stable quality, good safety and appropriate price. Don't blindly buy, blindly believe in the brand, or the sales promotion of the sales staff, you can refer to the above shopping guide to choose.
Two bogeys: if you don't learn, use it.
Someone bought an electric pressure cooker and used it without asking or learning. This is the most dangerous thing! When using the electric pressure cooker for the first time, you must read the instruction manual of the pressure cooker. Be sure to follow the instructions, or ask someone who knows what to do. Never use it without learning it.
Three bogeys: Do not check before use.
When using, first carefully check whether the exhaust hole is clear and whether the hole under the valve seat of the safety valve is blocked by residual rice grains or other food residues. If you are blocked by food during use, you should unplug the power supply and clean the air holes after forced cooling, otherwise the food will be sprayed out and burn people during use. Also check whether the rubber gasket is aging. Rubber sealing rings will age after a period of use. The aging apron is easy to make the pressure cooker leak and needs to be updated in time.
Four bogeys: the lid is not in place.
Before cooking food, the handle of the pot cover must be consistent with the indication sticker of the pot body, otherwise the pot cover is not good, the pressure does not come up, or the pot cover bounces up after the pressure comes up, which may easily lead to burns.
