AEG E6 fault codewhat it means and how to fix it
The hob is not getting the supply it was installed for. AEG give the cause as incorrect installation or insufficient power: induction hobs usually want a 16 amp supply where most homes have 13.

Get a qualified appliance engineer to look at your AEG E6
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.
What E6 means
AEG publish E6 and E641 as one entry on their electric hob support pages, and the cause they give is incorrect installation or an insufficient power supply. Until the spring of 2026 the same article put it more specifically — the appliance is connected to one phase only — and that older wording is still what most other sites repeat. Either way this is a code about the wiring rather than the hob, and AEG publish it for electric hobs and for cookers with an electric hob; the E6 on an electronic gas hob is a different code with its own page. AEG’s own steps start with the obvious: switch the hob off and back on with the power button, and if the code comes back, off at the fuse box for thirty seconds and try again.
If it survives both, the practical value of this page is a paragraph AEG put in their own installation check, which is the clearest statement of the underlying problem published by any manufacturer in this category. If you purchase an induction hob, these usually require a 16 amp installation, and most homes and normal plugs are 13 amps. If you have installed a 16 amp hob into a 13 amp socket you may see these error codes. That single fact explains a large share of the supply-side codes in this whole category. An induction hob is not a plug-in appliance, and a kitchen fitted out on the assumption that it is will produce codes from the day it is switched on.
What makes this worth catching early is the commercial consequence, which AEG also state: if faults arise due to the wrong installation this may not be covered under the warranty. So an owner who books a manufacturer engineer for E6 can end up paying for a visit that concludes the hob is fine and the wiring is not. The right call is to have the installation checked against the installation instructions first, by the electrician who did it if the kitchen is recent, and to book AEG’s Authorised Service Centre — the last step on their own list — only once the supply has been passed.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Incorrect installation or insufficient power supply | AEG’s stated cause. The hob is not receiving the supply the installation instructions call for, and refuses to run rather than half-work. | Common |
| Wired to a 13 amp supply when it needs 16 | AEG publish this as the practical UK case: induction hobs usually require a 16 amp installation and most homes and normal plugs are 13 amp. | Common |
| Connected to one phase only | The cause AEG published for this code until 2026, since replaced by the broader wording above. It describes a hob wired for a two-phase supply with one of the phases missing at the terminal block, or the links set for a supply that is not there. | Occasional |

What it costs to fix
Typical repair cost
£60–£200
Time on site
1h 30m
An electrician’s visit to check and correct the supply. If a 16 amp circuit has to be run to the hob from the consumer unit rather than just re-terminated, it sits at the top of this range or above.

Common questions about AEG E6
Can I just plug it into a normal socket?
No, and AEG are specific about why. Induction hobs usually require a 16 amp installation while most homes and normal plugs are 13 amp, and they name that mismatch as a cause of these codes. A hob needs its own circuit with the right protection, wired by an electrician.
Is E641 the same as E6?
Yes. AEG publish them together with the same cause and the same steps, and the difference is just which form the control board displays.
Other sites say E6 means the hob is on one phase only. Is that wrong?
It is what AEG used to say. Their E6 and E641 article gave the cause as the appliance being connected to one phase only until at least April 2026, and by August 2026 it read incorrect installation, insufficient power supply. The older line was a specific case of the newer one, not a contradiction of it: a hob wired for a two-phase supply with one phase missing is one way to end up under-supplied.
What about E5?
AEG publish E5 separately as a phase or voltage issue on integrated induction hobs and cookers with an induction hob. Their steps are the same as for E6: disconnect at the isolating switch for at least thirty seconds, then book service quoting the code if it returns. It is the same family of supply-side fault.
Will the warranty cover it?
Possibly not, and AEG say so: if faults arise due to the wrong installation this may not be covered under the warranty. That is a reason to establish whether the wiring is right before booking a manufacturer engineer, because a chargeable visit to a correctly working hob is an expensive way to find out.
