Dash air fryer will not start; display shows E1 immediately when power button is pressed.

Safety first: Unplug the air fryer and let it cool completely before opening or testing anything. Never work on the unit while it is connected to power.

Step 1 – Power reset

• Unplug the air fryer for at least 10 minutes.
• Plug it back into a known-good outlet (avoid power strips) and try again.

If E1 returns, continue.

Step 2 – Inspect the temperature sensor wiring

• Remove the basket and pan, turn the unit upside down on a soft surface.
• Remove the bottom screws to access the internal cavity (this may void warranty; if under warranty, contact Dash support instead).
• Locate the NTC temperature sensor near the heating element in the upper housing. It is usually a small metal probe or disc with two thin wires.
• Check that the sensor wires are firmly connected to the main control board and not pinched, burned, or broken.
• Reseat any loose connectors by unplugging and firmly reconnecting them.

Step 3 – Check sensor resistance (for advanced DIYers)

• With the unit still unplugged, disconnect the sensor plug from the control board.
• Use a multimeter set to resistance (ohms) and measure across the two sensor leads.
• A typical NTC sensor should read between about 50kΩ–200kΩ at room temperature (exact value varies by model). A reading of 0Ω (short) or infinite (open) indicates a bad sensor.

Step 4 – Replace faulty parts

• If the sensor is open/shorted or physically damaged, replace the NTC temperature sensor assembly specific to your Dash model.
• If the sensor tests good but E1 persists, the main control board sensor input may be defective and will need replacement by a qualified technician.

When to stop: If you are not comfortable opening the unit or using a multimeter, stop after the power reset and visual inspection and contact Dash or a professional appliance technician.
