Hi my optimax he 31c is losing water pressure, f37. This has happened numerous times now after refilling pressure to 1 bar within 2 hours it has gone again. I have also noticed my condenstae pump is running a lot more often every 18 mins, is it possible for the water to get into this line? how do i stop it? thanks.

check your pressure relief valve is not leaking...pipe that goes through wall to outside..if this is leaking theres your problem
