AEG F gas hob fault codewhat it means and how to fix it
On an electronic gas hob, F or E6 means a burner could not be ignited. AEG publish a reset sequence with a three-second window, and two different versions of it.

What F gas hob means
AEG make electronic gas hobs with a touch control panel and a display, which is why they are the only gas hobs in this research that show a numeric code at all. On those hobs, F and E6 both mean one or more burners cannot be ignited, and both have a documented reset. What is unusual is that AEG publish two different reset interfaces for the same code, because the panels differ between models. On one, you power the hob off and on, wait for the display to light and the F to reappear, then touch the pause key and, within three seconds, the Hob2Hood key.
On the other, you power off and on and, when the F reappears, press and hold the reset button for three seconds. In both cases the confirmation is the same: a zero appears on the display when the fault has been reset. The three-second window is real and it is why people report that the sequence does not work — it is easy to be too slow between the two touches.
The reset is not the fix, though, and AEG are clear that the same physical check applies either way. Check that the burner cap and the burner crown are correctly fitted, and that the metal part of the flame safety device is clean, using a moist soft cloth or sponge only. That is the actual cause in most cases: a cap put back slightly out of place after cleaning, or a residue on the probe, stopping the burner establishing a flame the hob can confirm. Resetting a hob whose cap is still misaligned will simply produce the code again on the next attempt.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Burner cap or crown incorrectly fitted | AEG’s named physical check and the usual cause. A cap that is not seated square puts the flame in the wrong place for ignition and for the safety device. | Common |
| A dirty flame safety device | AEG specify that the metal part must be clean and give the cleaning method — a moist soft cloth or sponge only. Residue on it stops the burner confirming a flame. | Common |
| A wet burner after cleaning | Water in the crown will stop ignition as effectively as debris, and it is the reason a hob often shows this the morning after a deep clean. | Occasional |
| An ignition component failing | If the burner is clean, correctly assembled and dry and the code returns after a proper reset, this is a service call rather than a cleaning job. | Occasional |
What to try yourself
Lift off the burner cap and crown for the burner that will not light. Check they are clean, completely dry and correctly seated when you put them back.
Clean the metal part of the flame safety device with a moist soft cloth or sponge only. AEG are specific about the method — nothing abrasive and nothing sharp.
Switch the hob off and on again. Wait for the light animation and for the F or E6 to reappear — the reset only works once the code is showing.
On a hob with a pause key, touch pause and then Hob2Hood within three seconds. On a hob with a reset button, press and hold it for three seconds instead.
Look for a zero on the display. That is AEG’s confirmation that the fault has been reset. If you do not see it, the sequence did not take — the three-second window is easy to miss.
If the code returns after a successful reset on a clean, correctly assembled burner, book a Gas Safe registered engineer.
Do not keep resetting a hob that will not light. Repeated ignition attempts release gas each time. If you can smell gas, do not touch any switch — leave and ring the gas emergency line from outside.
Get a qualified appliance engineer to look at your AEG F gas hob
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.

Common questions about AEG F gas hob
The reset sequence does not work.
Check two things. First, the code has to be showing when you start — AEG say to power off and on and wait for the F to reappear before touching anything. Second, the window between the two touches is three seconds, which is shorter than it sounds. If your panel has a dedicated reset button instead, the sequence is a single three-second press rather than two touches.
Is F the same as E6 on these hobs?
AEG publish both with the same meaning — one or more burners cannot be ignited — and the same reset approach. Which one you see depends on the model.
Why does this happen after cleaning the hob?
Because cleaning is when the burner caps come off, and they have to go back seated square and completely dry. AEG name both an incorrectly fitted cap and a dirty flame safety device as the checks, and water left in the crown will prevent ignition just as effectively as debris.
