How to Fix / Troubleshooting
Safety first: Unplug the cooker and let it cool completely.
- Improve airflow: Move the multicooker to an open, flat surface with at least 4–6 inches of clearance on all sides and above. Do not operate under low cabinets or near heat sources.
- Clean exterior vents: Use a soft brush or vacuum with a brush attachment to remove dust from any side or bottom vents.
- Allow extended cooling: Leave the unit unplugged for 30–60 minutes, then try again.
- Check room temperature: Ensure the room is within the operating range specified in the manual (typically normal indoor temperatures).
When to call a technician: If E06 appears even in a cool, well-ventilated environment, the internal board or its temperature sensor may be defective and require replacement.
