Unplug and Reset the Air Fryer
- Unplug your air fryer from the power outlet.
- Let it sit unplugged for at least 5 minutes, allowing internal circuits to reset.
- Plug it back in and turn on the device to see if the error clears.
This simple reset can resolve temporary glitches and is often the first step in troubleshooting error codes.
Inspect and Clean the Heating Element and Sensors
- Remove the basket and any accessories, following your user manual’s instructions.
- Check the heating element for food debris, grease, or burnt residue. Use a soft cloth or brush to gently clean it, ensuring it’s dry before reassembling.
- Locate the temperature sensor(s) — typically a small probe near the heating element. Wipe it clean with a damp cloth, avoiding abrasive materials.
Dirty or obstructed sensors can cause incorrect temperature readings, triggering error codes.
Check Electrical Connections and Wiring
Carefully examine the wiring connections inside the air fryer, especially around the control panel, heating element, and sensors. Look for loose, disconnected, or damaged wires. If you find any issues, ensure the appliance is unplugged before gently reconnecting or securing the wires. If wiring damage is evident, contact professional repair services or COSORI support for assistance.
Update Firmware and Contact Support if Needed
If your model supports firmware updates via the COSORI app, ensure your device has the latest version installed, as updates can fix bugs related to error codes. If the error persists despite your troubleshooting, contact COSORI customer support. Provide the error code, a description of your steps, and any relevant details. They can guide you through advanced troubleshooting or arrange repairs if necessary.
