I have a Baxi main combi Eco boiler. Yet again the pressure has dropped and I have the E119 code, the boiler man showed DH how to open the valve to repressureise it, but DH didn't show me and he is away until tomorrow night.
I think, but aren't sure, that I need to use a small screwdriver to loosen the second valve on the filling pipe (the other one I can open). Is this likely to be right?!
Please help me!
