I have one of the AEG touchscreen all singing all dancing ovens with the pyrolic self cleaning function etc. It tell oyu when it needs cleaning and all fancy stuff like that. Well when I now set it to clean which means it heating up to super high temperatures it stops with an F105 error code which apparently means its reached a temperature which is too hot. Super confused as I'm sure that's the whole idea of the cleaning process this oven is set for. The door locks and everything looks like it should, no shelves or items are left in the oven so I'm stuck.
Does anyone have any ideas? Its been working all well and good to my knowledge since installation which was about 2yrs ago and its not used to any excessive amount either.
