Step-by-step Troubleshooting for Common Error Codes
- Power Reset: Unplug the air fryer, wait 1–2 minutes, then plug it back in. This simple reset can clear temporary glitches.
- Check for Blockages and Clean Sensors: Open the basket and clean any grease or food debris from sensors and vents with a soft cloth. Ensure the basket is properly seated.
- Inspect the Basket and Components: Make sure the basket is correctly inserted and not warped or damaged. Remove and reinsert it securely.
- Test the Power Supply: Plug the air fryer into a different outlet to rule out electrical issues. Avoid using extension cords.
- Update Firmware or Reset Settings: If your model supports app control, check for firmware updates. Otherwise, perform a factory reset following the manual’s instructions.
- Overheating or Sensor Errors: Allow the appliance to cool down for 15–20 minutes, then restart. Overheating can trigger certain error codes.
Safety Tips and Precautions
- Always unplug the air fryer before cleaning or inspecting components.

Preventing Future Error Codes
Regular maintenance is key to preventing error codes. Clean your air fryer after each use, especially around sensors and vents. Avoid overloading the basket, as this can strain the motor and sensors. Use the appliance within recommended temperature ranges and follow the manual’s guidelines for safe operation.
Additionally, store the appliance in a dry, cool place and avoid exposing it to moisture or extreme temperatures, which can cause electronic faults over time.
