Air fryer will not start; display shows E1 immediately after power-on or when pressing Start.

Safety first: Unplug the Vida by PADERNO air fryer before opening any panels. Allow the unit to cool completely.

• Step 1 – Power reset: Unplug the air fryer for 5 minutes, then plug it back in and try again. Sometimes E1 can be a transient fault.
• Step 2 – Check sensor connector: Remove the rear or bottom cover (depending on model). Locate the small two-wire NTC temperature sensor clipped near the heating element or in the exhaust duct. Ensure the sensor plug is firmly seated on the main control board.
• Step 3 – Inspect wiring: Follow the sensor wires from the probe to the control board. Look for cuts, melted insulation, or broken conductors, especially where the harness passes near the heater or fan shroud.
• Step 4 – Test the NTC sensor: With a multimeter set to resistance (ohms), measure across the two sensor leads. A typical NTC will read between 5 kΩ and 200 kΩ at room temperature (exact value varies by model). If it reads open (infinite resistance), the sensor is defective and must be replaced.
• Step 5 – Replace faulty parts: If the sensor is open or physically damaged, replace the cabinet NTC temperature sensor with a compatible Vida by PADERNO part. If the sensor tests good but E1 persists, the main control board sensor input may be faulty and should be replaced by a qualified technician.

Warning: Do not bypass or short the temperature sensor; this can cause overheating and fire risk.
