Can the lid of the Xiaomi Electric Pressure Cooker 4.8L be opened during cooking?

No, for safety reasons, the Xiaomi Electric Pressure Cooker 4.8L has been designed with a lid protection feature.
For your reference, here are more details about the lid protection feature:
1. If you attempt to forcefully unlock and open the lid while the pressure cooker is in use, the cooking process will immediately pause, and all heating functions will stop;
2. At the same time, the display screen will flash a lid-unlocked icon, and an audible warning sound will activate to alert you that the lid is not securely closed;
3. If you re-lock the lid within 5 minutes, the cooking will automatically resume from where it left off. However, if the lid is not properly locked after 5 minutes, the pressure cooker will exit the cooking mode and return to the standby mode;
4. This protective mechanism ensures the safe use of the pressure cooker, reducing the risk of accidents due to sudden pressure release when the lid is improperly opened.
