Lid is stuck and will not open after cooking; float valve appears down but the lid will not rotate.

Safety first: Never force the lid open if you suspect the cooker is still under pressure. Serious burns can result.

• Check float valve: Confirm the float valve is fully dropped. If it is still up, the cooker is under pressure. Allow more time or carefully use the steam release to vent remaining pressure.
• Gently wiggle the lid: With the unit unplugged and cool, gently try to rotate the lid back and forth without forcing it. Sometimes the gasket can stick; a slight twist can free it.
• Inspect for external obstructions: Make sure nothing is pressing against the lid handle or locking tabs.
• Do not pry: Avoid using tools to pry the lid open; this can damage the locking ring and compromise safety.
• Service if jammed: If the lid remains stuck despite no pressure and gentle attempts, the internal lock mechanism may be bent or jammed and should be serviced by a professional.
