E13 appears when trying to start a pressure program; lid seems closed but unit will not proceed.

Safety first: Unplug the cooker before inspecting the lid lock. Never force the lid open if the unit might be under pressure.

• Verify no pressure: Ensure the float valve is down and no steam is escaping. Only then attempt to open the lid.
• Inspect latch movement: With the unit unplugged and open, move the lid latch back and forth. It should move smoothly without binding.
• Clean latch area: Remove any food residue or sticky buildup around the latch and strike plate using a damp cloth. Dry thoroughly.
• Test lock operation: Plug in the cooker, close the lid, and listen for a click from the lock solenoid when starting a pressure program. No click may indicate a failed solenoid or control issue.
• Do not bypass lock: The lid lock is a critical safety device. If E13 persists, have the lid lock assembly or control board inspected and replaced by a professional.
