Unplug and Clean the Air Fryer
- Unplug the air fryer and allow it to cool completely before cleaning.
- Remove the basket and any accessories.
- Use a damp cloth and mild dish soap to wipe down the interior, especially the heating element and fan area.
- Check for grease or food residue and scrub with a soft brush if needed.
- Dry all parts thoroughly before reassembling.
Remove and Manage Use of Liners
- Ensure you’re not placing liners in the basket during preheating, as trapped heat can cause smoke.
- Always place liners when the basket is filled with food, and avoid overfilling to prevent liners from flying up.
- Choose appropriate liners designed for air fryers, like the Cosori-specific liners, and avoid using thick or non-perforated types during initial preheats.
Check for Grease or Food Residue
Grease buildup is a primary cause of smoking. Regularly inspect and clean the basket and heating element to remove any accumulated residues.
If you notice any stuck-on grease, soak the basket in warm, soapy water or use a non-abrasive scrubber for thorough cleaning.
Inspect the Heating Element and Fan
Look for signs of damage, debris, or grease on the heating element and fan. Remove any debris carefully with a soft brush or cloth. If the element is damaged or corroded, contact COSORI customer service for repair options.
Tips and Warnings
- Always ensure the air fryer is unplugged before cleaning or inspecting parts.
- Do not use abrasive cleaners or steel wool on the interior surfaces.
- Use compatible liners to prevent grease splatter and ease cleanup.
- If smoking persists after cleaning, avoid using the appliance and contact support.
