How to Fix / Troubleshooting
Safety first: Unplug the unit and allow it to cool completely before further use.
- Improve ventilation: Move the cooker to an open, well-ventilated area away from walls, cabinets, and other heat sources. Do not operate under low-hanging cabinets where steam accumulates.
- Check vents: Inspect side and bottom vents for dust buildup or obstructions. Clean gently with a soft brush or vacuum.
- Limit back-to-back cycles: Allow a few minutes of cool-down between long or high-temperature programs.
- Persistent E09: Indicates likely failure of the internal fan or overheating components on the control board. Professional service is required; do not continue using a unit that repeatedly overheats.
