How do I fix my boilers' (Worcester Bosch 240) low pressure?

After recently bleeding the radiators in the house, the pressure on my boiler has gone down on the gauge to nearly zero. The heating seems unaffected however, the boiler makes a funny noise when the hot water is run, and is a bit worrying. How can I get the pressure back up and eliminate the noise?

There is a filling loop underneath the boiler which supplies the mains water to it. Turn it on until the gauge reaches 1.5bar and that should do the trick.

Iys usually silver with a black tap follow the larger pipes under the boiler.also look on top of boiler to see if its there may be lose and you got to connect it your self.

you should have a filling loop on the pipe work,usually below the boiler.Quite often silver with black taps.

Sounds like a daft question - but what does the filling loop look like?

YES, YOU NEED TO FIND THE FILLING LOOP, IF THE BOILER IS IN THE KITCHEN AND THE LOOP IS NOT UNDERNEATH, LOOK UNDER THE SINK.

Hi Jo
I am currently trying to solve exactly the same problem, and have got as far as finding out that there is a filling loop located near, or in, your boiler, and you need to let water into this loop by means of a tap. I can't find my loop or tap yet, but I hope that helps a bit!
