Vaillant boiler pressure

[cerenlulu]

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

Never seen or heard of the Vaillant premium rate number

If it is an ecotec plus turn the grey knobs under the boiler 90D when pressure guage reads about 10 o'clock turn one off then the other.

If it is an ecomax then the small filling loop is under the boiler at the front right hand corner as you look at the boiler.

You may have to drop the plastic cover under the boiler first.
