hi.please can any one shed some light on this problem.
my plumber said reason my boiler wont do central heating is that the cm927 system isnt working and comes up with code s.7 which means pump overun? but hot water works great.
so i purchase new cm927 get that correctly installed and it was pared up correctly. we set central heating to come on and yes ,the boiler fired up showing central heating rad pics ect then i felt pipe under boiler which started to get warm,
then it turned off, pressed i button and it said s.7 pump overun again,so we are baffeld after paying out a lot of money on new cm927 getting it fitted but same thing happens .please please can anyone shed any light on this.
as we have hot water but no central heating.
hope to here from some one soon
