My greenstar 37cdi combo boiler will not heat water.
Heating works fine and digital display holds at about 60ish. However, when I draw hot water from a tap, the display rises past 90, at which point the flame light goes out, then on to 107(U7). No hot water comes through tap.
I am also having to top up pressure every week.
