Reason:
If during the time of using the pot, at the steam outlet valve you hear a steam release and it is getting louder, then your pressure cooker must have encountered an open pressure relief valve, quickly venting.

How to fix:
You remove the sealing ring on the lid of the pot and check if there is any food attached to it, if so, clean it and reinstall it properly. Do not leave the sealing ring soiled or contaminated with food for too long as it will easily be damaged.
