Persistent food or rancid oil smell from the air fryer even after cleaning.

Safety first: Unplug and cool before deep cleaning.

Cleaning steps:

• 1. Deep clean basket and pan: Soak in hot, soapy water. Use a non‑abrasive sponge to avoid damaging non‑stick coating.
• 2. Clean interior surfaces: Wipe walls and heater guard with a mixture of warm water and mild detergent. Avoid soaking electrical components.
• 3. Heater area: With care, use a soft brush to remove baked‑on grease from the heater guard and surrounding metal. Do not bend the heating element.
• 4. Filters: If your Bosch model has a grease or odor filter, remove and clean or replace it according to the manual.
• 5. Burn‑off cycle: After cleaning and drying, run the air fryer empty at high temperature for 10–15 minutes in a well‑ventilated area to burn off residual odors.

Note: If odors persist and you see oil staining inside insulation or behind panels, professional disassembly and cleaning may be required.
