Step 2: Clean the Basket and Heating Element
- Remove the basket and wash it with warm, soapy water. Use a non-abrasive sponge to remove grease and food residue.
- Inspect the heating element at the top of the unit. Use a soft brush or cloth to gently remove any accumulated grease or crumbs.
- Dry all parts thoroughly before reassembling.
Step 3: Check for Proper Use of Accessories
- Ensure you’re using accessories compatible with your COSORI model, like the recommended ALJ 3PCS Air Fryer Oven Mesh Rack for even cooking.
- Avoid placing liners or accessories in the basket during preheating or without food to prevent them from flying up and igniting.
Step 4: Avoid Overfilling the Basket
Overloading the basket can cause grease and food particles to spill and smoke. Fill the basket only to the recommended level and shake or turn food for even cooking.
Step 5: Use Liners Correctly
If using liners, do not place them during preheating. Always ensure there is enough food on top to prevent liners from flying up and touching the heating element, which can cause smoke or fire.
