Unusual grinding or scraping noise when opening or closing the lid.

Safety first: Unplug the cooker before working on the lid mechanism.

Inspection:

• Open the lid fully and inspect the hinge area for food debris or foreign objects; clean thoroughly.
• Check the hinge pin for bending or misalignment.
• Observe the lid lock cam as you open/close the lid; look for rubbing or deformation.

Lubrication:

• Apply a very small amount of food-safe silicone lubricant to the hinge pivot points (avoid getting any on the sealing surfaces).

Resolution: If the hinge or lock cam is cracked or severely worn, replace the lid hinge assembly or complete lid. Do not force a stiff lid; this can damage the lock and compromise safety.
