E8 error appears and the unit will not start, or shuts down shortly after heating begins.

Safety first: Unplug the cooker and allow it to cool completely. Overheat conditions can damage plastic parts and wiring.

• Clear ventilation: Ensure all side and bottom vents are free of dust, grease, and obstructions. Clean with a soft brush or vacuum.
• Inspect for burns: Remove the inner pot and inspect the heating plate for heavy burnt-on residue. Clean gently with a damp cloth once cool; do not scratch the aluminum surface.
• Check environment: Operate the cooker on a heat-resistant, open surface with good airflow. Avoid enclosing it in cabinets during use.
• Reset: Leave the unit unplugged for at least 30 minutes to allow internal components to cool and any thermal cutouts to reset.
• Test with water only: Fill the inner pot with 2–3 cups of water and run a low-heat program. If E8 returns quickly, an internal sensor or board fault is likely.
• Replacement: If vents are clear and the heating plate is clean, but E8 persists, the main control board or associated sensors may be defective. These should be diagnosed and replaced by a qualified technician.
