Adam thoroughly diagnosed the fault and concluded that even if the circuit board has been chabged, there were no guarantee that there were other problem in the boiler. just changing the circuit board costed over £600. He suggested the boiler was old and it could be better to install a new one. He was honest about it and did not give me any false hope to the boiler that it could be worth the money for the repair.
