Possible Causes

Misaligned lid, Damaged lid gasket channel, Cracked lid body near hinge, Warped inner pot causing uneven lid pressure

How to Fix / Troubleshooting

Safety first: Do not touch escaping steam. Unplug and allow the cooker to depressurize naturally before inspection.

Inspection steps:

  • Remove the inner pot and sealing ring. Inspect the lid body, especially near the hinge, for hairline cracks or warping.
  • Check the gasket channel for chips or deformation that could prevent a proper seal.
  • Verify that the inner pot sits evenly and does not rock; replace if warped.

Resolution: Minor channel debris can be cleaned; structural cracks in the lid or hinge area require replacement of the complete lid assembly. Continued use with a cracked lid is unsafe.
