Error code E125 indicates a problem with circulation in the primary circuit. Resetting the boiler is unlikely to help, and could cause an additional problem.

A problem with circulation could be down to a failing/failed pump, but that's not the only possible cause. How old is the installation (apart from the boiler)?
