Air Fryer
E3
The E3 error code on a Salter air fryer indicates an overheating fault — the appliance has detected that its internal temperature has exceeded a safe operating limit and has shut itself down as a precaution. It’s a common issue and usually fixable at home without professional help.
What does this error mean?
The E3 code means the air fryer’s thermal sensor has registered temperatures above the safe threshold, typically caused by inadequate airflow or a malfunctioning temperature sensor. The appliance cuts power automatically to prevent fire risk or damage to internal components. Until the root cause is resolved, the fryer will not operate.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and unplug the air fryer immediately, then leave it to cool on a hard, flat surface for at least 30 minutes before doing anything else.
Check the ventilation clearance — Salter recommends at least 10–15cm of clear space on all sides and above the unit. Move it away from walls, cabinets, and other appliances.
Clean the air vents, basket, and drawer using a soft brush or damp cloth. Pay particular attention to the rear vent grille where grease builds up and blocks airflow.
Reduce the amount of food in the basket to no more than half to two-thirds full, and shake or turn food halfway through cooking to keep airflow consistent.
Plug back in and run a short test cook at a lower temperature (around 160°C) for 5 minutes. If the E3 code does not return, the issue was likely a one-off overheat from poor ventilation or overloading.
If the E3 error returns immediately or when the unit is cold, the temperature sensor is likely faulty. Do not attempt to open the appliance or handle internal components — contact Salter support or a repair technician.
📞 When to call a professional
If the E3 code reappears after cleaning, repositioning, and reducing load — especially if the unit feels cool to the touch — the internal NTC thermistor or heating element is almost certainly faulty and needs professional diagnosis. Contact Salter’s UK customer support (0800 612 6377) first, as the appliance may still be under its 3-year warranty. Tell the technician: ‘My Salter air fryer is displaying an E3 overheating error that returns even when the unit is cold and unobstructed.’
⚖️ Repair or replace?
A professional repair for a faulty temperature sensor or heating element typically costs £50–£90 including labour, which is often close to or exceeding the cost of a new entry-level Salter air fryer (£40–£80). If your appliance is over 3 years old and out of warranty, replacement is usually the more cost-effective choice. If it’s within the 3-year Salter warranty period, claim a repair or replacement directly through Salter before spending any money.
