Step 1: Perform a Basic Reset
- Turn off the air fryer and unplug it from the power outlet.
- Wait at least 5 minutes to allow internal components to reset.
- Plug the air fryer back in and turn it on.
- Check if the error code has cleared. If it persists, proceed to the next step.
Step 2: Inspect Power Connection and Outlet
- Ensure the power cord is securely connected to the air fryer and the outlet.
- Test the outlet with another device to confirm it supplies power.
- If you notice any damage to the cord or plug, replace or repair it before further use.
- Try plugging the air fryer into a different outlet to rule out outlet-specific issues.
Step 3: Clean Sensors and Heating Elements
Over time, grease and food particles can accumulate on temperature sensors and heating elements, causing error codes related to temperature sensing or overheating.
To clean:
- Unplug the device and allow it to cool completely.
- Use a soft, damp cloth or a soft-bristled brush to gently clean the sensors and heating elements inside the basket and around the heating chamber.
- Avoid harsh chemicals or abrasive scrubbers that could damage components.
- Once cleaned, reassemble and test the air fryer.
Step 4: Check Internal Components and Wiring
If error codes continue, consider inspecting internal wiring for loose connections or damage. Only attempt this if you are comfortable with basic electrical safety.
- Unplug the unit and remove the outer panels if possible, following your user manual instructions.
- Look for disconnected wires, burnt spots, or damaged connectors.
- If you find any issues, secure loose connections or contact a professional for repairs.
- Reassemble carefully and test the device.
Step 5: Update Firmware or Contact Support
If your model supports firmware updates, check the COSORI app or website for the latest software. Updating can resolve bugs that cause persistent error codes.
If issues remain after all troubleshooting, contact COSORI customer support. Provide detailed information about the error code, your troubleshooting steps, and purchase details for faster assistance.
