Once or twice a day the boiler overheat comes into operation and shuts off the appliance. It can be reset and works again.

Had same problem on new build house. The radiators had not been balanced, some were effectively blocked off presumably causing circulation to heat up too quickly and overheating. This was not the adjustable valve but the inlet adjustment on the other side of the radiators. Check all radiators are emitting full heat with adjustable valves on full.
