My Gas boiler wa in red and i reset and it ran for few minutes then stopped . I checked pressure gauge in hotpress and noticed it was below 1 bar, I turned pressure valve and got pressure upto 2 bar.Still boiler would come on for few minutes then switch off and no heat getting to radiators. Checked rad downstairs to see if any airlock and only water came out.
Any ideas before I call someone what I could try?
