Hi therekeep getting F12 up and Fh up, i have done a reset and it clears it for a while, is this a common problem? I have a Optimax 38C.
Also there is a thumping inside which wasnt there when i bought it, it is when the heating switches off to heat the water and visa versa, the gentleman who came round to repair said 'thats what they do!!!' Can you help at all. Shall i launch it off a cliff?
Regards, Rich.
