Hi
If posted before apologised, i tried searching and couldn't find.
I noticed this morning the water was cold out of the shower even though after a while it should have been warm.
Looked at the Ideal boiler. And it had the F1 code showing.
So followed online advice and set the pressure to 1.5
This got rid of the F1 message but this now changed to "C"
The heating was on.
But now when turning hot water taps on, nothing comes out.
Cold water tap works.
Have I broken something or caused a new issue?
