Lid is stuck and cannot be opened after cooking; float valve appears down but lid will not rotate.

Safety first: Never force the lid open. If any steam is still escaping, wait until it stops completely.

• Check for residual pressure: Gently move the steam release valve to ensure no steam remains. If steam escapes, wait longer.
• Cool-down: Allow the cooker to cool fully; metal parts may contract and release tension.
• Inspect vent and float: Once open, clean the steam vent, float valve, and lid lock area thoroughly to remove any food that could jam the mechanism.
• Lubricate lightly: Apply a tiny amount of food-safe silicone lubricant to moving plastic parts of the lock if they are sticking (avoid sensors and electrical parts).
• Replace damaged lock parts: If plastic components are warped or broken, replace the lid lock assembly.
