Step 2: Clean the Basket and Heating Element
- Remove the basket and any accessories. Wash the basket thoroughly with warm, soapy water, paying special attention to the bottom and sides where grease can accumulate.
- Use a soft brush or non-abrasive sponge to clean the heating element, gently removing any grease or food particles stuck on it.
- Dry all parts completely before reassembling.
Step 3: Check for Residue or Food Debris
Inspect the inside of the basket and the heating element for grease, oil, or food debris. Remove any buildup carefully using a damp cloth or soft brush. Consider using a mixture of vinegar and water for tough spots, then rinse thoroughly.
Step 4: Use Liners to Prevent Future Buildup
Disposable air fryer liners, like the COSORI Air Fryer Liners, can help contain grease and food residue, making cleanup easier and reducing smoke. Place liners when cooking, but avoid preheating with liners in the basket.
Step 5: Check for Mechanical or Electrical Issues
If cleaning doesn’t resolve the smoking, inspect the power cord and plug for damage. Also, look for signs of a malfunctioning heating element or other internal parts. If you notice any damage, contact COSORI customer support or a professional technician for repair.
