Step 2: Remove and Inspect the Basket
- Carefully remove the basket and tray from the air fryer.
- Check for food residue, grease, or crumbs stuck in the basket or on the heating element.
- If you see buildup, proceed to cleaning.
Step 3: Clean the Basket and Heating Area
- Wash the basket, tray, and any removable parts with warm, soapy water or dishwasher (if dishwasher safe).
- Use a soft brush or cloth to remove grease from the heating element carefully.
- Dry all parts thoroughly before reassembling.
Step 4: Check and Use Proper Liners
If using disposable liners, ensure they are placed correctly—never during preheating—and that they are not overloaded with food. Use liners designed for your basket size to avoid blockage or fire risk.
Step 5: Examine for Damage and Test
Inspect the heating element and power cord for any signs of damage. If you notice cracks, discoloration, or malfunction, contact customer support or consider professional repair. Once cleaned and checked, plug in the air fryer and run a short test without food to see if smoking persists.
