1. Check whether the power supply of the pressure cooker has been unplugged. If the power supply of the pressure cooker has not been unplugged, let's unplug the power supply of the pressure cooker first and make sure that the pressure cooker is in a dead state before exhausting.

2. Cover the pressure cooker with a clean rag, and then turn the air leakage valve on the pressure cooker by hand to let the steam be discharged from the air leakage valve. Covering with a rag can prevent steam from spraying out and scalding our hands.

3. Press the manual exhaust valve in the middle of the electric pressure cooker, and more gas will be discharged from the pressure cooker.
