Multicooker shows E7 and may beep continuously, refusing to start or continue cooking.

Safety first: If the cooker is under pressure, do not force the lid. Use the recommended pressure release method and keep clear of steam.

• Allow full depressurization: Wait until the float valve drops fully and there is no steam escaping before attempting to open the lid.
• Inspect lid lock mechanism: With the unit unplugged and cool, open the lid and examine the locking pin and surrounding plastic. Clean away any food residue or dried sauce that may be jamming the mechanism.
• Check lid lock movement: Gently move the locking pin (if accessible) to ensure it slides freely. Do not force it.
• Clean around float valve: Remove and clean the float valve and its channel to ensure it can rise and fall freely, as this often interacts with the lock system.
• Test operation: Reassemble, plug in, and close the lid firmly. Start a non-pressure program (e.g., "Sauté") to see if E7 clears. If the error persists, the lid lock solenoid or sensor may need replacement.
