Lid is stuck and will not open after cooking

Safety first: Do not force the lid open. Forcing can cause sudden release of hot steam and food.

• Check pressure indicator: Verify that the float valve has dropped. If it is still up, there may be residual pressure.
• Gently vent steam: Carefully move the steam release valve to Venting using a long utensil. If steam escapes, wait until it stops completely.
• Tap float valve: Once cool, gently tap the float valve from the top with a spoon to free it if stuck.
• Inspect lid lock: After opening, inspect the lid lock pin and surrounding plastic for deformation. Clean any food residue.
• Replace lock assembly: If the lock mechanism is damaged or binding, replace the Cosori lid lock assembly to prevent future sticking.
