Air fryer powers on but will not start cooking; pressing start does nothing or beeps only.

Safety first: Disconnect from mains before mechanical checks.

• Confirm setup: Ensure time and temperature are set, and the basket is fully pushed in until it clicks.
• Check for error icons: Some Tefal models show a drawer or lid icon instead of a code; if lit, reinsert the basket firmly.
• Reset electronics: Unplug for 5–10 minutes, then reconnect and try again.
• Inspect basket rails: Look for bent rails or debris preventing full insertion. Clean and straighten gently if needed.
• Switch/panel diagnosis (advanced): If the start button does not register, the touch panel or start switch may need replacement.
