Hi
My low water pressure light is flashing this is due to me draining the system to replace three radiators, which is correct. My question is why has my DHW stopped working, the demand when tap turned on operates the DHW micro switch but nothing else works, PCB looks alright, I have a spare but still the same problem. Help required.
Thanks

Because the boiler has to have the correct pressure to provide central heating or hot water, fill the system and the hot water will work.
