Lid is stuck and will not open after cooking; float valve appears to be down.

Safety first: Do not force the lid open. There may still be residual pressure inside.

• Check float valve: Ensure the float valve has fully dropped. Gently tap the lid near the valve to help it settle.
• Release residual steam: If your model has a manual valve, carefully move it to the vent position with a long utensil. If no steam escapes, pressure is likely gone.
• Inspect lock area: Once you are sure there is no pressure, gently wiggle the lid while lifting the handle. Do not use excessive force.
• Clean after opening: When you manage to open the lid, clean the lock channel, float valve, and surrounding areas thoroughly to remove dried food.
• Service if jam persists: If the lid remains stuck or the lock mechanism is visibly bent, have the lid lock assembly inspected and replaced by a technician.
