Lid is difficult to close or open; requires excessive force or feels jammed.

Safety first: Ensure the cooker is not under pressure before forcing the lid.

• Clean hinge and lock: With the cooker unplugged and cool, clean the hinge area and lock mechanism with a brush and warm soapy water. Remove dried food or starch.
• Lubricate lightly: Apply a tiny amount of food-safe silicone lubricant to metal hinge pins if accessible (avoid getting any on seals).
• Inspect for bending: Check the hinge arms and lock latch for visible bending or damage. Replace the hinge or lock assembly if deformed.
• Check gasket seating: Ensure the lid gasket is properly seated and not twisted, which can make closing difficult.
