    hello
    I am really hoping someone can advise me as my boiler hasn't been working for several days. it's a glow worm 30xi combi, 8 years old.

    first the pressure dropped to 0.3bar but i couldnt get it to fill when turning the tap. Using the instructions on one of the forums, i checked inside the fill valve (twice) and that seems to be working fine.

    when i first noticed the low pressure started, cold water would flow from the hot tap. Since I shut off the water at the stop cock, the cold taps are fine but nothing at all comes out of the hot tap. I can't find any isolating valves.

    it seems to me that the boiler wont fill because no water is coming in. but why is that when it is a combi boiler with mains pressure. can't be an airlock surely?

    any comments gratefully received!
