I have a Biasi Activ A 150V. it is only 7 months old. the boiler is only used as a back up for our woodburner and solar thermal to heat the thermal store and has probably only been run for about 10 hours since commissioning. The little spanner has illuminated (no fault code). According to the manuals this indicates the boiler needs a service. Surely this cannot be correct after so little time and so little running. Can this indicator be reset?
