Need some help here guys, I've got a Promac Club Me that is leaking from the anti vac valve. I've read all previous posts on this fault and cleaned all parts with no change. I ve got a gut feeling it's the computer /touch panel. All is fine until I turn the boiler on then at it heats up out it comes. Also I think the water level is way to high as once it reaches temp water also come out of the safety pressure valve?
Any ideas?
