Multicooker displays E2 and will not heat or start the selected program.

Safety first: If the cooker was in use, unplug it and allow it to cool for at least 30–60 minutes before further checks.

• Allow full cool-down: Leave the lid open and inner pot removed so trapped heat can escape. Do not attempt to restart until the base is cool to the touch.
• Check for dry cooking: Confirm there was sufficient liquid or food in the pot. Running the cooker empty can trigger E2. Always follow Breville's minimum liquid guidelines.
• Inspect inner pot bottom: Ensure the bottom of the pot is flat, clean, and free of burnt-on residue that could cause hot spots or poor contact with the heating plate.
• Clean heating plate: Wipe the aluminum heating plate gently with a soft, slightly damp cloth. Remove any carbonized food or oil, then dry completely.
• Test with water: After cooling and cleaning, add 2–3 cups of water to the pot, reinstall it, and run a low setting (e.g., "Slow Cook Low"). If E2 reappears quickly, the thermal sensor or thermal fuse may be faulty and professional service is advised.
