Yesterday I drained my CH to replace a leaking drain cock beneath a radiator, all went OK until I came to get it running, Cyl stat calls for heat and boiler/pump work, but as soon as I put the room stat up to call for heat the boiler cuts out leaving pump running. Checking volts at the wiring box there is live on both H/W ON & HW Off connections when it's in this state!!
My guess is that it's the V4073A gone wrong, but am too confused as to know why I think thats whats wrong, anyway its a coincidence if it failed at the same time as doing the plumbing downstairs.
Any ideas?
