Possibly. They’re noted as a difficult boiler to work on. They suffer a series of issues. You need a gas safe registered engineer to look at it, it needs testing to see if it’s the full board or part of it, some boilers have secondary fuses in the board. A decent engineer will advise if it’s financially viable to repair, or if replacement is better.
