Mend Vaillant F28 Boiler Pressure System

villant f28, which valve do i open to fill pressure into the pressure bar?

we tried to open the valves that are under the boiler because the pressue bar is 0. but we are not sure which one to open as there are about seven valves down there. can anyone help

You may find that there isn't a flexipipe there but solid pipe, but either way there is a valve with a small black lever on it and at the other end is a slightly longer valve with no lever but an arrow on it's side. Open the lever until the pressure is about 1.5bar, check to make sure there are no leaks around the house as to why the pressure was lost!!
