Silicone lid gasket has become loose, stretched, or has a strong odor.

Safety first: Ensure the cooker is cool before removing the gasket.

• Clean gasket: Wash the gasket with warm soapy water and let it air dry completely.
• Deodorize: Soak in a solution of water and a small amount of vinegar or baking soda to reduce odors, then rinse and dry.
• Inspect for damage: If the gasket is stretched, cracked, or no longer fits tightly, replace it.

A worn gasket can prevent proper pressure sealing and should be replaced with an All-Clad compatible part.
