My boiler is a Worcester Combi 28CDi RSF. I drained the system to remove two radiators (one permanently) but it will not refill. The pressure gauge is showing zero and although I have let if fill for some time the gauge is not moving. Every now and then as it is filling, there is a loud clanking sound which I assume is coming from the pressure relief valve as water is coming out of it (pipe in garden) at the same time. According to the info I have, the system pressure should be 1 bar and the pressure relief valve should actuate at 3 bar. Its starting to get cold so any advise would be greatly appreciated.
Thanks Steve
