The following guidance applies to any air fryer. Error codes may have different meanings depending on the brand and model.

Air fryer not listed: code guide and common problems

E1, E2, E3, and other codes do not have a universal meaning: they vary by brand, model, and version. Use this guide only for orientation and always check your fryer's manual.

Initial safe checks
  1. Turn off and unplug the fryer from the electrical outlet.
  2. Wait for the appliance to cool down completely.
  3. Check that the basket, drawer, lid, or probe are inserted and closed correctly.
  4. Verify that the air vents and fans are not obstructed.
  5. Turn on again only if there is no black smoke, intense burning smell, damaged cord, or visibly deformed components.
Meaning of codes (E1, E2, etc.)

Reset and restart

Reset / Power cycle
Generic Guide

Diagnosis

1. Turn off the appliance and unplug it from the socket. 2. If it is hot, let it cool down completely before restarting. 3. Wait at least 10–15 minutes before plugging it back in. 4. Reconnect the appliance and check if the problem persists. 5. If the model has a specific procedure in the manual, follow it. 6. If sparks, a burning smell, abnormal smoke, or electrical issues appear, unplug the appliance and contact support. Please note: this is a general restart procedure, not a specific diagnosis.

E1

Thermal / Sensor Error
Severity: Severity: Medium
Generic Guide

Diagnosis

Hardware Repair (Frequent on: Cosori, Ninja, Philips). Usually indicates a fault in the NTC thermistor or temperature sensor. Solution: unplug the fryer, perform a hard reset by leaving it off for 15 minutes. If the problem persists upon turning it on, service is required.

E2

Sensor Short Circuit
Severity: Severity: Medium
Generic Guide

Diagnosis

Hardware Repair (Frequent on: Cosori, Ariete, Moulinex). Often signals a sensor short circuit or severe overheating. Solution: unplug immediately from the power source, visually check if the ventilation grilles are clear and wait for it to cool. If it reappears, it requires repair.

E3

Overheating Protection
Severity: Severity: Medium
Generic Guide

Diagnosis

Software Reset (Frequent on: Ninja, Generic, Proscenic). Typically indicates the activation of the overheating protection or a poorly positioned basket. Solution: verify the basket insertion, move the appliance at least 15cm away from the wall, let it cool, and try again.

E4

Power or Malfunction
Severity: Severity: Medium
Generic Guide

Diagnosis

Software Reset (Frequent on: Ninja, Cosori). Often associated with board communication problems or fan/voltage anomalies. Solution: unplug the appliance, check if the fan is spinning or obstructed. Avoid extension cords or multi-adapters and connect it to a wall outlet.

Display Spento

No Power
Severity: Severity: Medium
Generic Guide

Diagnosis

Hardware Repair (All brands). May indicate a defective basket microswitch or a blown thermal fuse. Solution: make sure you hear the basket 'click' when inserted. If it doesn't turn on in other outlets, contact support.

Common problems

The fryer will not turn on

Check that the plug is securely inserted and the outlet is working. Make sure the basket is completely closed, as many models have a safety microswitch.

The basket or drawer is not detected

Remove and reinsert the basket by pushing it all the way in. Check for any food residue blocking the closure or the contact sensor.

White smoke during cooking

This is often caused by very fatty foods (e.g., sausages, bacon). The fat drips to the bottom and burns. You can try adding a tablespoon of water to the bottom of the outer basket before cooking to reduce smoke, or empty excess fat.

Black smoke

Turn off the appliance immediately. There could be food stuck on the upper heating element, or a potential electrical fault. If it's not caused by burnt residue, do not reuse it and contact support.

Food undercooked or not crispy

Do not overload the basket. Make sure to shake the food halfway through cooking and consider slightly increasing the time or temperature compared to standard instructions.

Uneven cooking

Foods are overlapping too much. Cook in smaller batches and ensure air circulates freely around the food.

Display error reappears after turning off

If an error persists after unplugging the appliance for 15-20 minutes, it usually indicates a faulty sensor or circuit. Avoid DIY repairs on electrical components and consult support.

When to stop using and call support
  • • Turn off the appliance immediately. There could be food stuck on the upper heating element, or a potential electrical fault. If it's not caused by burnt residue, do not reuse it and contact support.
🧠 Why does the error appear?

Modern air fryers feature built-in microcomputers that constantly monitor the thermistor (heat sensor) and fan airflow. When an error code appears, the motherboard has cut power to prevent a potential fire. About 60% of errors are 'false positives' solvable with a software reset, while the remaining 40% require hardware replacement.

Frequently Asked Questions about Breakdowns and Error Codes

What to do if white smoke comes out of the air fryer?
White smoke is caused by excess fat accumulating at the bottom and burning, or by residues from previous cooking. Turn off the appliance, let it cool down, and thoroughly clean the basket and the heating element. To avoid this, do not cook overly fatty foods without a little water at the bottom.
What do the E1 or E2 error codes mean?
In most models (e.g., Cosori, Xiaomi, Princess), the E1 and E2 codes indicate a problem with the temperature sensor (open circuit or short circuit). Do not try to repair it yourself: unplug the appliance and contact customer support.
How do I reset my air fryer?
For a basic reset (hard reset), unplug it from the power outlet for at least 10-15 minutes. This allows the capacitors to discharge and the electronic board to reboot. If the error persists upon restarting, the hardware is likely damaged.
When is it absolutely necessary to call customer service?
You must contact support if error codes (such as E1, E2, E3) persist after a reset and after the machine has completely cooled down, or if you notice severe physical symptoms like black smoke, sparks, or a strong smell of burning plastic.
Why does the display show the message 'Pot' or 'Out'?
These messages indicate that the safety sensor does not detect the presence of the basket. Check that it is pushed all the way in (it should make a metallic 'click'). If the problem persists, the contacts between the basket and the machine body might be dirty or bent.
