Lid will not open after cooking; float valve appears down but lid remains stuck.

Safety first: Never force the lid open if there is any chance of remaining pressure.

• Check for steam: Gently move the steam release valve to ensure no steam escapes. If steam is present, wait longer.
• Tap around lid: Once cool and depressurized, gently tap around the lid and handle to free any sticking gasket.
• Clean lock area: After opening, clean the lid lock pin and surrounding area thoroughly to remove dried food.
• Inspect for damage: If the lid frequently sticks, inspect the lock mechanism and consider replacing the lid lock assembly.
