Hi

Our boiler has broken down and won't light and we think it is because the pressure has gone to nothing. I seem to recall the plumber who fitted it saying that you needed to turn two screws a quarter turn underneath, however, there isn't anything in the instruction booklet. Does anyone know how to do this?

Thanks.

Hi Underneath the unit where all the pipes go in there is probably a label identifying which pipe is the cold water feed for the boiler. It will say CWin or CWF or something like that. It's probably the leftmost pipe as you look at the boiler from the front and will come from the cold taps in your house. If you follow the pipe from say 2 feet away from the boiler to where it disappears into the bowels of the unit (and you won't have to undo anything for this but you'll probably be upside down looking up into the bottom of the unit, you'll see a little valve that looks like a radiator bleed valve actually built into the pipe. Get a bleed key and use it to open this valve to let water into the boiler until the pressure gauge reads in the green. It's probably best if you turn off the boiler electricity supply whilst you're doing this just to appease the health and safety police!. I found that the head of the valve was a really crap fit in the key so you'll have to hold it carefully in position so as not to slip. You'll hear a hissing noise whilst the water goes in which will stop when you close the valve again. You'll need to bleed the radiators probably as well and then go back and check the pressure again because you'll have let water out in the bleeding process. Toodle pip
