Hello,
We have a Vaillant boiler (Model VUW242E) which keeps losing pressure. In roughly 10 hours it goes from 1 Bar to 0. During this time the water is leaking from the overflow letting air into the system. It only recently started doing this and I would like to try and fix it myself. Would anyone have any idea what has failed to cause this problem?
