What's wrong with the lid of the electric pressure cooker?

Turn the lid clockwise. If the lid moves, it means there is no air pressure in the pot. If the pot doesn't open, it will stop cutting and prevent you from opening the lid. You can find a hard object (such as chopsticks), press the one-way valve to return it to its original position, and then you can open the lid.

There is still air pressure in the pot.

If you rotate the lid clockwise, it may be that there is still air pressure in the pot and it must be cooled and released. Generally, it is natural cooling, air cooling and boosting. If you are not in a hurry to boil, you'd better use natural cooling to release the pressure. Generally speaking, there is no need to increase the pressure to release it unless absolutely necessary.

There are too many accessories on the pot cover.

There are too many foreign bodies attached to the pot cover, so it is necessary to clean the residue in the pot cover in time and often to ensure the cleanliness of the pot cover.

Extended data:

Before opening the lid, make sure that there is no air pressure in the pot, then remove the pressure limiting valve to ensure that there is no air pressure in the pot before opening the lid, or use cold water for forced cooling to reduce the pressure in the pot, and wait until there is no gas discharged from the pot before opening the lid.

Pressure cookers on the market are protected by opening and closing covers. For example, when there is air pressure in the pot, the safety lever is in the rising stage, and then the pot cover cannot be opened according to the normal use method. When there is no air pressure in the pot, the safety lever descends and the pot cover can be opened safely. When exhausting, keep your hands or face away from the exhaust port to avoid burns.
