Hi folks..I have a combi boiler which is not firing up for CH or hot water. The pilot is fine but the pressure gage is way below the red gage line. It's on zero. I'm thinking it may be a simple process of bleeding rads or turning a tap to get the pressure up & get it working again but not sure. I don't want to pay loads of money for an engineer just to get a rad key out or do something I could do! Can anyone advise what I could try before getting an engineer? I did try a key on the rads but it was water & not air that came out making me think the rads are OK? I did have a new pressure valve fitted in August.
thanks
