Step 1: Turn Off and Unplug the Air Fryer
Before inspecting or cleaning, always turn off your COSORI air fryer and unplug it from the power outlet to prevent accidents and ensure safety.
Step 2: Clean the Heating Element and Fan
- Allow the air fryer to cool completely.
- Remove the basket and any accessories.
- Wipe the heating element and fan area with a damp cloth or soft brush to remove grease or food particles that may be causing smoke.
Step 3: Check and Clean the Basket and Interior
- Remove the basket and wash it thoroughly with warm, soapy water. Use a brush to scrub away any stuck-on grease or residue.
- Dry all parts completely before reassembling.
Step 4: Ensure Proper Use of Liners and Fill Levels
If using liners, make sure they are positioned correctly, not during preheating, and that food is not overfilled. This prevents grease from dripping onto heating elements and causing smoke.
Step 5: Test Run and Monitor
After cleaning, run the air fryer empty at a high temperature (around 400°F) for 10 minutes to burn off any residual manufacturing oils or dust. Watch for smoke; if it persists, repeat cleaning or inspect for other issues.
