Hello All.
I have just changed by 3 way diverter valve and all is well for the hot water.
But when switched to the heating, the boiler tries to start up but after 15 seconds or so, the red LED Low Pressure appears.
The pressure is at a good pressure.
Please can anyone advise how to get around this and for the heating to work?
I have attached some images to help.
Thank you.
