i have a Worcester Bosch R 30/35/40 and the pressure gauge is showing practically zero. the boiler is still working fine but obviously want to up the pressure back to a more normal level.
we have done this before successfully so am fairly confident we are doing it right: turn the value on the cold water inlet pipe 90 degrees and then there is a screw above it that needs loosening - water should flow in. but nothing is happening.
any ideas what is wrong? could the value be blocked and is there a way we can unblock it ourselves?
any help would be great thanks.
