Hi All
Had a look through the forum but can't spot what I'm looking for.
I have a Vaillant ecotec 831, just recently I noticed the CH is not getting up to temp. I normally have it set about 60c but it can't seem to get the temp above 35-40ish at the moment no matter what it's set to. The 'C' with up arrow is on the display looking like its trying to do it, no error messages etc. Normal tap hot Water temp seems fine.
This all started after I had a ground floor rad leak the system completely dry, not sure if that is just coincidence!? Occasionally get some noise from the pump since re-filling the system too, but most the time it's fine. I've checked the screw on the pump and clean water comes out, no sludge etc.
Anyone with ideas what I could look at/what it might be?
Cheers
Mike
