That problem was so obvious to me that I am surprised that you did not just reverse the connections on your first visit.
Its pretty common in London that some kind of third world plumber has fiddled with the boiler before I get there.
One had ALL the lower parts in a heap on the floor but that was an RGI as by chance his trainee came to me later and remembered the visit and that unusually he was unable to find the fault.
