Hi
The combination boiler that I have a problem with is a: Chaffotaeux et Maury Sterling FF. The pressure on the boiler keeps going high. And there appears to be a water leak at the top of the change over valve where the micro switch is fitted, can this be repaired? Also does the rise in pressure mean there is a ( water to water ) internal leak in the secondary heat exchanger?
Thanks
