AEG [C2] fault codewhat it means and how to fix it

The same caveat applies here as to C1 and C3. Where an AEG oven lists its pyrolytic cycles by name, C2 is the middle one — normal cleaning, an hour and a half — and picking it is an ordinary thing to do rather than a problem. The fault is the message the oven raises on its own, printed as Err C2 in the manuals that use the prefix and as bare C2 on AEG’s website. Higher-specification AEG ovens come with a core temperature probe — AEG call it the cooking thermometer or the food sensor — that plugs into a socket inside the oven and reads the temperature at the middle of a joint. C2 means that probe is still there when you have asked for a pyrolytic clean.

The reason this catches people out is that plenty of owners have never used the probe and do not know their oven has one, so the code names a component they cannot picture. AEG tell you where to look: the socket is on the top right inside the oven.

Worth knowing that AEG define this code two different ways. Their website says the probe is in the connector; their manual says it is in the oven cavity. Those are not the same claim, and the manual’s is the wider one — a probe lying loose on a shelf would satisfy it. Take the whole thing out and you have covered both readings. It is worth doing rather than working around, because the probe is a precision component with a cable, and the cycle it is sitting in front of runs at roughly 500°C.

1. 1

   Look at the top right of the inside of the oven. That is where AEG say the probe socket is, and it is easy to miss because it sits above eye line.

2. 2

   Pull the probe plug out of the socket and take the whole lead out of the cavity.

3. 3

   Shut the door and start the pyrolytic programme again.
