Hi, need some help with this one please.
Lady next door has no heating. I've looked and the pressure guage is at zero.
However, i cant get it to fill and she has no instructions. Underneath the combi on the cold inlet and heating return i can see 2 blue plastic knobs. A small filling loop connects these. Turning both of these has no effect. I loosened the filling loop where its screwed into the check valve on the heating side and plenty of water began to drip.
Is there something i'm missing or do the filling valves on these seize up. How do i fill this combi??
Many thannks.
