Lid does not lock properly; pressure builds but steam escapes around the lid lock area.

Safety first: Do not operate the cooker under pressure if the lid does not lock securely.

• Inspect latch: With the cooker unplugged and cool, open and close the lid while observing the latch hook. It should engage firmly.
• Clean latch area: Remove any food residue around the latch and lock slot.
• Check for play: If the lid wiggles excessively when locked, the lock mechanism may be worn.
• Internal inspection (advanced): Access the lid lock assembly from inside the lid or top cover. Check for broken springs or plastic parts.
• Replace the lid lock assembly if it does not hold the lid securely or if the safety interlock does not engage.
