Simply stopped heating water. Had a hot shower, had breakfast, but no hot washing up water. Boiler makes noises when running hot water tap but only cold comes out.
Checked and no pilot light. It will not relight.
I increased the water pressure to between 1 and 2 bar as it was a little low, but that did not help.
There is electricity because the ?pump/fan is operating. I assume there is gas. Any ideas please.
