Hello,
My Vaillant boiler stopped working last night. it's showing the F.22 fault code on the display and basically i think it's because the pressure has dropped to 0. Does anyone know how i can get the pressure back?? in my old home i used to turn a valve at the back to let the pressure in and it seemed to be a very easy thing to resolve by myself without having to call in a plumber or phone the Vaillant premium rate technical helpline!
any advice appreciated!
Thanks,
Ceren
