Lid is difficult to close or feels like it is grinding or catching when turning.

Safety first: Unplug the cooker before inspecting the lid mechanism.

• 1. Clean rim and tracks: Wipe the stainless rim and the lid locking tracks with a damp cloth. Remove any hardened food or scale.
• 2. Inspect hinge: Open the lid fully and check the hinge area for cracks or bent metal. Tighten any loose hinge screws.
• 3. Check for warping: Place a straightedge across the body rim and lid sealing surface. Significant gaps indicate warping; in this case, the lid or body may need replacement.
• 4. Lubricate lightly: Apply a tiny amount of food-safe silicone lubricant to the plastic locking lugs if they are dry and squeaking (avoid the sealing surfaces).
