Valiant boiler. F22 error which is low / no pressure. Website says leak but we're not pissing water anywhere...
Ideas / thoughts welcome.
Have you bled and refilled the system this winter? What pressure is there in the system now? Can you refill it and get it started again?
Having had the same issue, how old is the boiler and when was the pressure vessel pressure checked.
