E8 error code appears and the cooker will not start pressure programs.

Safety first: Ensure the cooker is unplugged before manipulating the lid lock mechanism.

• Verify lid lock: Close the lid and rotate/lock it firmly until you hear or feel a click. Some Emeril Lagasse models require the lid to be aligned with a specific mark.
• Inspect locking pin: Open the lid and observe the locking pin or hook. Move it manually (if possible) to ensure it is not jammed with food residue. Clean with a damp cloth.
• Check for obstruction: Ensure no utensil, gasket edge, or warped inner pot rim is preventing the lid from closing fully.
• Test again: Plug in, close and lock the lid, and start a short pressure cycle. If E8 persists, the lid lock sensor or actuator may be defective.

Do not attempt to bypass the lid lock. Replacement of the lid lock assembly is recommended and should be done by a professional.
