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

Safety first: Unplug the Beko air fryer from the mains and allow it to cool completely before opening any panels. Never work on a live appliance.

Steps to check and address E1:

• Power reset: Unplug the unit for 5–10 minutes, then plug back in and try again. If E1 returns, continue.
• Access the sensor: Remove the basket and drawer. Turn the unit upside down on a soft surface. Remove the screws securing the bottom cover to access the heater housing and wiring.
• Locate the NTC sensor: On Beko air fryers, the NTC temperature sensor is usually clipped or screwed to the metal heater housing or air channel near the heating element. It has two thin wires leading to the main PCB.
• Check connections: Inspect the sensor plug where it connects to the main control PCB. Reseat the connector firmly. Look for broken, pinched, or burnt wires.
• Test the sensor: With a multimeter set to resistance (ohms), measure across the NTC sensor terminals. A typical reading at room temperature is between 50 kΩ and 200 kΩ (exact value varies by model). If the meter shows OL (open) or 0 Ω, the sensor is faulty.
• Replace if faulty: If the sensor is open or physically damaged, replace it with a compatible Beko NTC temperature sensor. Route the new sensor wiring away from hot or sharp edges and secure it with existing clips.
• Inspect the PCB: If the sensor tests good but E1 persists, inspect the main control PCB for burnt tracks or corrosion at the sensor input. In most cases, a faulty PCB must be replaced rather than repaired.

When to stop: If you are not comfortable using a multimeter or removing covers, or if the PCB appears damaged, contact a qualified appliance technician.
