Step 2: Unplug and Allow Cooling

Step 3: Clean and Inspect Components
- Remove the basket and any removable parts. Wash thoroughly with warm, soapy water and dry completely.
- Check the sensors and heating element for food residue or debris. Clean gently with a soft cloth or brush if needed.
- Inspect the wiring and connections for visible damage or loose contacts.
Step 4: Reset the Air Fryer
After cleaning, plug the unit back in. Many COSORI models can be reset by unplugging for 3-5 minutes, then plugging back in. This can clear temporary faults and error states.
Step 5: Test and Monitor
Turn on the air fryer and run a short cooking cycle to see if the error reappears. If the error persists, try repeating the cleaning process or consult the user manual for further troubleshooting steps.
