AEG oven fault codes
Two things to know before you look up an AEG oven code. If it starts with C, it is not a fault at all — it is the oven telling you it cannot start a pyrolytic clean until you have taken something out, and every one of them is a one-minute fix. If it starts with F, be prepared for a short answer, because AEG list around 74 F codes and publish the meaning of almost none of them. And if your oven is lit but stone cold with no code at all, check the clock and check for the word Demo before anything else.
Where the code shows on a AEG
The single most useful thing to know about AEG oven codes is that AEG document two different sets of them, in two different places, and the sets barely overlap. Their support website publishes a table of about 74 F codes, defines none of them, and heads the section as codes requiring a service call-out. The manual that came with the oven publishes around ten codes, defines every one, and introduces them as "the list of the problems that you can handle on your own". Not one of the manual’s ten appears in the website’s seventy-four, and only two of them, C2 and C3, appear anywhere on the website at all, on a separate article about pyrolytic prerequisites. So if your code is on the website list you have been told it needs an engineer and nothing else; if it is on the manual list there is a free fix and the website will never show it to you. We have built pages from both. Note also that AEG describe their own table as covering "some" codes, so it should not be read as complete. Codes on this platform are precise: F131 means F131, and F130 is a different fault. There is no truncation here of the kind Electrolux Group use on their tumble dryers, where the displayed code is deliberately the family rather than the exact alarm — carrying that assumption across would be actively wrong. On the badge question, AEG, Zanussi and Electrolux share one code system and one documentation template: we compared three manufacturer-hosted manuals under the three badges and the "oven does not heat up" table is word-for-word identical in all three, down to the advice about a fuse that blows repeatedly. What they do not share is the published code set, which tracks the features of the individual appliance rather than the badge on it. A pyrolytic Zanussi we checked documented no codes at all in its troubleshooting table, while the equivalent AEG documented three. Two more things about how these codes are actually written. Some AEG manuals prefix them with Err — the display reads Err F102 or Err C3 rather than F102 or C3 — and no page on AEG’s support site uses that prefix anywhere, so a reader searching exactly what is on the glass is searching a string the manufacturer’s own website never publishes. Both forms find the right page here. And the prefix is doing real work rather than decorating: in the manuals that use it, C1, C2 and C3 are also the names of the three pyrolytic cleaning cycles — light, normal and thorough cleaning, at one hour, an hour and a half and up to three hours (the thorough cycle is three hours in most AEG manuals and two and a half in at least one). Err C3 means the door is not closed. Plain C3 selected from the menu means the longest clean. AEG’s website refers to the fault without the prefix, which collapses the distinction their own manuals rely on.
How to reset a AEG
AEG give two different intervals and the difference is deliberate, so it is worth using the right one. For a fault code or a display that has stuck, their instruction is to turn the oven off at the mains, wait 30 seconds, and switch it back on. For a pyrolytic door that will not unlock after the oven has fully cooled, the interval is longer: turn it off at the mains, wait 10 minutes, then switch back on and restart the appliance. On a built-in oven "at the mains" means the cooker switch on the wall or the breaker in the consumer unit, not a plug — AEG’s own F102 article talks about plugging the oven back in, which does not describe how most of their integrated ovens are installed. One thing a reset will not fix: if the oven has lost its clock it will come back flashing, and on a touch-control model it will not heat until the time is set again.
Most common AEG faults
The AEG codes people look up most.
- F1Get it checkedOne code, two published meanings. On a pyrolytic AEG oven it is about the door not closing. On a non-pyrolytic one AEG call it an electronic fault and send you straight to service.
- DemoUsually simple to fixThe oven lights up, accepts settings and never heats. AEG admit demo mode can switch itself on after a power cut, and the code to switch it off is 2 4 6 8.
- C3Usually simple to fixTwo different things share this label. Selected from the cleaning menu it is a three-hour clean. Shown on the display as Err C3, it means the door is not closed.
- F102Get it checkedThe one F code AEG actually define for the UK. They put it down to the door lock or the electronics, and give you two things to try before booking an engineer.
