Same problem. Part D "Removable connection" is not connected and I'd say it never has since the way it's installed they can't fit it together. Boiler has worked for 9 months now.

I open both black valves and NO difference at all. Keep getting F37 error. What do you suggest?

It may sound simple Roy but have you opened the filling loop and topped the boiler up with water pressure to around 1 Bar? If this is the problem you should have a F37 code showing. If it's not this, then it's the pressure sensor. More than likely the low water pressure though.
