When removing the old pressure cooker ring, clean the position where the pressure cooker washer is placed. At the same time, soak the new pressure cooker ring in hot water until it is soft and then install it to increase its flexibility.
It is necessary to check and replace the ring of the pressure cooker regularly. The washer often fricts with the lid of the cooker in daily use, causing it to crack or damage, which leads to the failure to cook food normally.
