Step 2: Clean the Basket and Interior
- Remove the basket and wash it with warm, soapy water. If you use disposable liners, remove them and clean the basket thoroughly.
- Wipe down the interior, including the heating element, with a damp cloth or soft brush to remove grease and food residue.
- Ensure all parts are dry before reassembling.
Step 3: Check and Remove Excess Grease
Inspect the heating element and interior surfaces for accumulated grease or oil. Use a soft cloth or non-abrasive brush to gently clean these areas. Accumulated grease can cause smoke when heated.
Step 4: Use Liners Properly
- Do not place liners during preheating or without food. Always ensure liners are weighted down with food to prevent them from flying up and touching the heating element.
- If using disposable liners, select the right size and avoid overcrowding.
Step 5: Adjust Cooking Settings and Loading
Reduce the temperature slightly if smoke persists. Avoid overloading the basket, as overcrowding can trap grease and cause smoke. Shake or turn food midway to promote even cooking and minimize smoke formation.
