Vaillant EcoFIT pure leaking water from behind condensation trap

I have a Vaillant ecoFit pure 830 which developed the f.22 fault, the pressure had dropped to 0.2 bar, i refilled the system and away it went, i noticed yesterday that there was water on the floor below the boiler and noticed that water was leaking from a small hole located behind the condensation trap. This leak is lowering the pressure but i don't know and can't find anything on what is causing it.

Does anyone know what might be causing the issue and how might it be fixed?

Thanks in advance
