Grinding or scraping noise when opening or closing the lid.

Safety first: Ensure the cooker is unplugged and cool before working on the lid.

• Inspect hinge area: Open the lid fully and look for food debris or hardened grease around the hinge and lock hook. Clean with a damp cloth and mild detergent.
• Check for bent parts: If the lid appears misaligned or rubs against the body, inspect the hinge brackets for bending. Minor bends can sometimes be gently straightened.
• Lubricate lightly: Apply a tiny amount of food-safe silicone lubricant to the metal hinge pins only, avoiding any surfaces that contact food or steam.
• Test operation: Open and close the lid several times to distribute lubricant and confirm the noise is reduced.

Warning: Do not use cooking oil as a lubricant; it can become sticky and attract dirt.
