2. The electric control element of Midea electric pressure cooker is faulty. In this case, you can only go to the after-sales maintenance point or ask professional maintenance personnel to handle it.
It may be that the electric pressure cooker has been used for too long and has not been cleaned. In this case, the pressure has dropped to normal atmospheric pressure, but due to oil pollution, food residue, oxide and other reasons, the resistance between the safety valve and the lid increases, and it is impossible to naturally drop to the position where the lid can be opened normally. If this is the case, you can open the safety valve by poking it with chopsticks, but you should keep a safe distance. After opening it, you should clean up the sundries between the safety valve and the cover in time to avoid the next failure.
4. It may be that Midea electric pressure cooker suddenly loses power when it is used, and the check valve does not fall when it is powered off, resulting in the pot cover not being opened. If this is the case, make sure to press the check valve with chopsticks after pressure relief, so that the cover can be opened clockwise after the check valve falls.
