Step 1: Power Reset and Basic Checks
- Unplug the air fryer from the power outlet.
- Wait at least 1-2 minutes to allow internal components to reset.
- Plug the air fryer back in and turn it on.
- Check if the error code reappears.
If the error persists, proceed to inspect sensors and connections.
Step 2: Inspect and Clean Sensors and Heating Element
- Open the air fryer basket and inspect the temperature sensors, typically located near the heating element.
- Use a soft, damp cloth to gently wipe away any grease, food particles, or debris.
- Ensure the sensors are dry before reassembling.
- Check the heating element for any visible damage or dirt. Clean if necessary.
Dirty sensors can cause false error readings. Proper cleaning may resolve sensor-related error codes.
Step 3: Verify Proper Placement and Accessories
Ensure that no accessories, liners, or food debris are blocking airflow or sensors. If using liners, make sure they are placed correctly without covering vents or sensors, and do not preheat with liners in place.
Improper placement can trigger error codes related to overheating or airflow disruption.
Step 4: Check for Firmware Updates or Control Panel Reset
Some error codes may be related to software glitches. Check if there are firmware updates available via the COSORI app or website. Follow instructions for updating your device.
If no update is available, perform a control panel reset by unplugging the unit, waiting 10 minutes, then plugging it back in. This can clear temporary glitches.
When to Contact Support or Replace Parts
If error codes persist after troubleshooting, the issue may involve faulty sensors, wiring, or internal components requiring professional repair or replacement. Contact COSORI customer support with the error code details for guidance.
Avoid attempting internal repairs beyond cleaning and inspection to prevent voiding warranties or causing further damage.
