I had no hot water but the boiler fired up when a tap was opened.
The central heating was working perfectly.
The 3amp fuse blew overnight which suggested an electrical fault so I replaced the 3-way motor and the diverter valve.
Now I have perfect hot water and the boiler fires up for the central heating according to the temperature control. I have it set low at 61-64 degrees, and the water is gravity feeding one of two radiator upstairs, the other is cold. The feed to the downstairs radiators is cold below the T-junction to upstairs.
The pump sounds like it running OK so I am at a loss as to what it is.
Thought about shorting 1/2 on J10 as per manual to see if it is the 230v control board?
Anybody find this story familiar please?
