Multicooker will not start a cooking cycle and displays E0 on the control panel.

Safety first: Unplug the multicooker and allow it to cool completely before inspecting the lid or internal parts.

• Check lid closure: Open and firmly close the lid several times. Make sure the lid arrow/mark aligns with the body mark and that the lid is fully latched.
• Inspect lid hinge and latch: Look for bent metal, broken plastic tabs, or food debris around the latch and hinge area. Clean with a damp cloth and a soft brush.
• Check for lid switch actuation: With the unit unplugged, gently press the lid latch mechanism and listen/feel for a small click from the lid switch. If there is no click, the switch or actuator may be damaged.
• Clean lid sensor area: On some Breville multicookers, a small plastic post or magnet on the lid interacts with a sensor in the body. Wipe both surfaces to remove grease or residue.
• Test again: Plug the unit back in, close the lid firmly, and try a simple program like "Sauté" or "Slow Cook". If E0 persists, the lid switch or control board likely needs replacement and professional service is recommended.
