What means c1 on aeg oko lavamat 74500


Hello!

Error C1 on AEG Lavamat usually means that there is a trouble with water filling. The required water level is not reached.

I reccomend you contact your local Service
Force Centre.

Here is the link to a manual of a similar AEG Lavamat waching machine (a "trouble shooting" part). Hopefully, it will help!
