My Glow Worm Swift Flow 80 is showing zero pressure on the dial. How do I re pressurise the system. I found a red knob which appears to contain the pressure switch behind the pressure dial. If I try to turn this it appears to have a spring and snaps back if I try to turn it - I don't want to force it. Am I in the right place?
Is there an on-line manual for this boiler??
Hi Andy, found the braided hose/tap and it now works a treat.
Do you know how to adjust the boiler temperature (as opposed to the rads) it's very high.
Can I get a user manual anywhere? - Many Thanks Andy, Mike (now Warm!)

Nope, you are twisting the pressure relief valve there. Look for a metal braded hose or similar, which will be connecting one of the central heating pipes to the mains water pipe. (this will be external to the boiler itself) This will have a valve on it (it may be slot head so you will need a screwdriver) open this and repressurise to 1bar when cold. (wont matter if you go a little over).
You may find you loose pressure again, if this happens you will need to get advice as it is most likely you have a flat expansion chamber or possibly a slight leak.
Also you may of lost pressure if you have been bleeding radiators.
