Air fryer error codes
A code on an air fryer means whatever that company's firmware author decided it means. There is no standard, no registry and no convention, and reading one manufacturer's meaning across to another's machine is the single most likely way to misdiagnose a fault. This page holds what has actually been read in manuals, attributed, and nothing else.
Questions this answers
- What does E1 mean on my air fryer?
- Is there a standard list of air fryer error codes?
- My air fryer shows an error — can I reset it?
Twelve of fifteen manufacturers publish nothing at all
Of the fifteen manuals read for this catalogue, twelve contain no fault documentation whatever. One publishes five display states with no codes. One publishes a ten-code table split by zone. One publishes two codes and two symptoms.
That ratio is the finding. A page listing dozens of codes with confident meanings would be drawing on somewhere other than manufacturer documentation, and there is nowhere else to draw on that would be worth reading.
The same code is not the same fault
One manufacturer's E1 is an open circuit in a temperature monitor. That tells you nothing about anybody else's E1. The same manufacturer even writes the same code differently on two models in its own range — E1 on one and E1\E21 on another — which is a small demonstration of how little a code travels.
AirfryerHQ therefore holds error states scoped to a manufacturer, always, and a validation rule refuses to attach one to a model belonging to a different company. Where a code is not held, the page says so and points at the manual rather than guessing.
What the published states actually mean
The pattern across the three manufacturers who publish anything is consistent: sensor-circuit faults go straight to customer support with no user action offered, and overheat protection is the one state where the user is given something to do — turn it off, unplug it, let it cool completely, and contact support if it persists.
The states that read like faults and are not deserve as much attention. One manufacturer's ADD FOOD means preheating has finished. Another's cycling heating elements are a thermostat working. Both are searched as errors, and both are in the register so that somebody searching finds out they are fine.
If the appliance has stopped and shown a code
Unplug it at the wall. Do not repeatedly power-cycle it to clear a code, and do not carry on cooking through one — an appliance that reports a fault has detected something about itself that you cannot see. If the state relates to overheating, find out why it overheated before using it again: ventilation clearance, obstructed vents, and accumulated fat are the three causes worth checking.
The states these manufacturers actually publish
Component fault
E1- What the manual says it means
- An open circuit in the upper temperature monitor of zone 1.
- What to do
- The manual offers the user no action at all for this code and directs them to customer support. That is the whole of the manufacturer's published position, and AirfryerHQ does not supplement it.
- Can it be reset?
- The manual does not say
- Does it need service?
- Yes, the manual says so
Stop using it and contact the manufacturer

A protection device has operated
E3- What the manual says it means
- The appliance's zone 1 overheat protection has activated. This is a protection device doing its job rather than a component that has failed.
- What to do
- Turn the appliance off, unplug it, and allow it to cool completely. If the display still shows the code after that, contact customer support.
- Can it be reset?
- Yes, the manual says so
- Does it need service?
- The manual does not say
Stop, unplug, and let it cool
An overheat protection device operates because something made the appliance too hot. Before using it again, check the obvious causes: obstructed vents, insufficient clearance around the appliance, accumulated fat in the pan or on the element, or an ambient temperature the appliance was not designed for. If the code returns, stop using it and contact the manufacturer — a protection device that keeps operating is telling you something.

Published without a stated cause
E- What the manual says it means
- The manual says only that the unit is not functioning properly. There is no further detail published, and "E" is the entirety of this manufacturer's fault-code vocabulary for this appliance.
- What to do
- Contact the manufacturer's customer service on the number printed in the manual. No user action is offered and none should be invented — a single undifferentiated fault code means the appliance has detected something it will not tell you about.
- Can it be reset?
- The manual does not say
- Does it need service?
- Yes, the manual says so
Stop using it and contact the manufacturer

A protection device has operated
PRBE ERR- What the manual says it means
- The appliance timed out before the food reached the internal temperature set on the probe. The manual frames this as a protection measure: the unit can run only for certain lengths of time at specific temperatures.
- What to do
- Not a fault in the appliance and nothing to reset. Check the probe is pushed lengthwise into the thickest part of the food, and expect to restart the cook. If the food was frozen or much larger than the probe programme expects, that is the likeliest reason it timed out.
- Can it be reset?
- Yes, the manual says so
- Does it need service?
- No, the manual says not to
Something you can correct
The food will not have reached the temperature you set. Do not treat a timed-out probe cook as finished — for poultry, pork or minced meat, the governing food-safety rule applies and the food needs more cooking, not less.

A protection device has operated
-----Five dashes on the display- What the manual says it means
- The manual states that a safety feature has activated because the appliance has overheated.
- What to do
- Unplug the appliance and let it cool for one minute before plugging it in again. If it happens again, the manufacturer's own framing is that this is a fault rather than a cooking problem.
- Can it be reset?
- Yes, the manual says so
- Does it need service?
- The manual does not say
Stop, unplug, and let it cool
A safety feature has operated because the appliance got too hot. Before using it again, check the ventilation clearance around and above it, that nothing is obstructing the vents, and that fat has not built up in the pan or on the element. A protection device that operates repeatedly is reporting a cause that has not been removed — stop using the appliance and contact the manufacturer.

Blue sparks or crackling during combination cooking
- What the manual says it means
- The manual identifies this as arcing, caused by an unsuitable metal container or by insufficient food in the oven. It is specific to combination cooking, where microwave energy and convection heat run together.
- What to do
- Stop the programme immediately, and either change the container or reprogramme to convection only. The manual is specific that metal tins and foil containers must sit directly on the enamel tray on the glass turntable and never on the wire rack.
- Can it be reset?
- Yes, the manual says so
- Does it need service?
- No, the manual says not to
Stop, unplug, and let it cool
Arcing inside a microwave cavity can damage the appliance and start a fire. Stop the programme rather than letting it finish, and do not repeat the same combination of container and mode. If the cavity, the turntable or the door has been damaged, stop using the appliance and contact the manufacturer.

Evidence and confidence
- Applies to
- Specific to this manufacturer
- Why this rating
- Every meaning on this page was read in a manufacturer's own documentation and is attributed to it. The page's argument — that a cross-brand table is impossible — is supported by the observation that one manufacturer uses different code formats on two of its own models.

What this does not cover
- AirfryerHQ holds error states for four manufacturers. A code not held here says nothing about the appliance — it means this catalogue does not have that manufacturer's documentation.
- No code meaning here comes from anywhere but a manual. Nothing has been taken from a forum, a retailer listing or a general code list.
