Air Fryer
E5
The E5 error code on a Gourmia air fryer signals a temperature sensor fault — the appliance has detected an abnormal reading and shut down to prevent overheating. It’s a self-protection measure, and in many cases you can resolve it yourself without calling an engineer.
What does this error mean?
The E5 code means the air fryer’s internal thermistor (temperature sensor) has sent a reading that’s either too high, too low, or completely absent — outside the range the unit expects during normal operation. The appliance interprets this as a potential overheating or sensor failure risk and cuts power to the heating element as a precaution. It won’t restart until the issue is cleared, which can be as simple as letting it cool down or as involved as a sensor replacement.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and unplug the air fryer immediately. Leave it on a cool, open surface for at least 30 minutes to fully cool down before doing anything else.
Check the ventilation. Ensure there’s at least 10–15 cm of clear space around all vents — typically at the rear and base. Move the unit away from walls or under-cabinet spaces.
Clean the basket, drawer, and interior. Remove the basket and wash it thoroughly. Use a damp cloth to wipe down the inside walls and around the heating element (when fully cool and unplugged), removing any grease or food debris near the sensor area.
Plug back in and run a test. Switch on the unit with an empty basket for 3–5 minutes on a moderate setting (around 180°C). If the E5 code doesn’t return, the issue was likely heat build-up or airflow.
If the error returns immediately or persists, perform a factory reset if your model supports it — consult your Gourmia manual (or the Gourmia support site at gourmia.com) for the exact button combination for your model number.
If none of the above clears the code, the thermistor itself has likely failed. Do not attempt to open the appliance casing or tamper with internal wiring — this is a job for a repair technician or the unit may need replacing.
📞 When to call a professional
If the E5 error returns every time you power on, even after a full cool-down and clean, the thermistor or control board has most likely failed and needs professional diagnosis. Contact Gourmia’s UK customer support first — many units carry a 1–2 year warranty and may be replaced free of charge. If out of warranty, tell a local appliance repair technician: ‘My Gourmia air fryer is showing an E5 error — I believe it’s a thermistor or temperature sensor fault.’
⚖️ Repair or replace?
A professional repair involving a thermistor replacement typically costs £50–£90 in labour plus parts — often approaching or exceeding the cost of a new mid-range Gourmia air fryer (£50–£120 new). If your appliance is more than 2–3 years old and out of warranty, replacement is almost always the better financial decision. For a newer unit still under warranty, always contact Gourmia before spending a penny on repairs.
