Step 2: Allow the Air Fryer to Cool
Wait at least 30 minutes for the unit to cool completely, especially if it has been used extensively. This prevents burns and allows safe handling of parts.
Step 3: Clean the Basket and Interior
- Remove the basket and any accessories, such as mesh racks or liners.
- Wash the basket, tray, and accessories with warm, soapy water or in the dishwasher if dishwasher-safe.
- Use a soft brush or cloth to remove grease and food residue from the interior walls.
- Pay special attention to the heating element and fan area, clearing any accumulated grease or food particles.
Step 4: Check and Remove Obstructions
Ensure no liners, accessories, or food debris are blocking the airflow or touching the heating element. Replace or reposition liners carefully, avoiding placing them during preheating.
Step 5: Inspect for Grease or Food Residue
If you notice significant grease buildup, consider removing and thoroughly cleaning the heating element and fan area with a soft brush or cloth. Avoid using abrasive materials that could damage the unit.
Step 6: Dry and Reassemble
Make sure all parts are completely dry before reassembling. Reinsert the basket and accessories securely. Do not overfill the basket to prevent grease from dripping onto the heating element.
Step 7: Test the Air Fryer
Plug in the unit, set it to a low temperature, and run it empty for 5-10 minutes to see if smoking persists. If smoke is gone, your cleaning and inspection were successful.
