Hi, I've just had to install a new radiator (new position) so had to drain the system. This time I kept the flow & return valves open when I drained he system. Now after I filled the system back up and got the pressure back up the boiler won't fire up. (Worcester HiFlow 400 sealed system). Any ideas why?
Have I got air in the pump and would this stop the ch starting?
I also accidently let some air out of the expansion vessel inside the boiler, would that make any difference?
If so The manual says that the pressure in here should be 1/2 bar, Can I use a bike pump and how will I know the pressure is at the right setting?
Many Thanks for sugestions.
