Lid is stuck and cannot be opened after cooking, even though pressure appears to be released.

Safety first: Do not force the lid open. Confirm that pressure is fully released before attempting any action.

Steps to safely release:

• Verify no pressure: Gently move the steam release valve to ensure no steam escapes. If steam is present, wait until it stops completely.
• Tap around lid: Lightly tap around the float valve and lock area with a wooden spoon to free any stuck parts.
• Cool the cooker: Allow the unit to cool further; internal components may release as they contract.
• Once open, clean thoroughly: After the lid opens, clean the float valve, lock pin, and surrounding areas to remove any dried food.

When to call a technician: If the lid remains stuck despite no pressure and gentle attempts, professional disassembly is recommended to avoid damage.
