Air Fryer
E4
The E4 error code on a Gourmia air fryer indicates an overheating fault — specifically that the internal temperature has exceeded safe operating limits. It’s a protective shutdown, not a death sentence for your appliance, and is often fixable at home in minutes.
What does this error mean?
Gourmia air fryers use a built-in thermal sensor to monitor internal temperature throughout the cooking cycle. When that sensor detects temperatures beyond the safe threshold — typically triggered by restricted airflow or a faulty component — the unit throws an E4 code and cuts power to prevent damage or fire. Think of it as your air fryer’s emergency brake.

🛠️ Step-by-step fix
Step 1 — Power off and unplug: Switch off the air fryer and unplug it from the mains immediately. Leave it to cool for at least 20–30 minutes before doing anything else.
Step 2 — Check placement: Make sure the unit has at least 15cm of clear space on all sides and above. Move it away from walls, cupboards, and other appliances.
Step 3 — Clean the vents and basket: Once cool, remove the basket and drawer. Wash them in warm soapy water and use a dry cloth or soft brush to clear any grease or debris from the air intake vents on the back and base of the unit.
Step 4 — Inspect the interior for grease: Check inside the cooking chamber for baked-on grease near the heating element. Wipe down with a damp cloth — never submerge the main unit. A grease-coated sensor can trigger false E4 readings.
Step 5 — Plug back in and test: Reconnect the power, run the air fryer empty for 5 minutes at a moderate temperature (around 180°C), and check whether the E4 code returns.
Step 6 — Reduce load and rest between cycles: If the error only appears during heavy use, cook in smaller batches and allow 5–10 minutes between cooking sessions to let the unit cool down.
📞 When to call a professional
If the E4 error persists after cleaning, correct placement, and a full cool-down, the temperature sensor or heating element may need replacing — both require opening the appliance’s casing, which is not a safe DIY task. Contact Gourmia customer support first, as units under two years old may be covered under the manufacturer’s warranty. If out of warranty, a small appliance repair specialist can diagnose and replace the faulty component; tell them the unit shows an E4 overheating fault code.
⚖️ Repair or replace?
Professional repair of a faulty temperature sensor or heating element on a Gourmia air fryer typically costs £50–£90 in labour alone — often close to or exceeding the cost of a new mid-range model (£40–£90). If your Gourmia is over two years old and out of warranty, replacement is almost always the more economical choice. For a unit under 18 months old, pursue the warranty claim before spending anything.
