Hi,

Can any one help with some advice please. I have a Biasi Combi Boiler. We've got the hot water to work. The pressure gauge was stuck but we've got it working. However, the central heating won't work. When we switch the power on the central heating will switch on but then shuts off after about 10 or 15 seconds.

Can anyone offer any advice on what the best thing to do is to check whats wrong? I've read that it can be a flow issue sometimes? We bled the radiators and they all seem to have water at the top. There is one radiator that has been built next to a sink. If you can't bleed one radiator. can this become a block for the water? An airlock maybe?

Any help would be much appreciated?
