Location:
Resistance tests have revealed no reason for fuse/s failure. Replace fuse/s (correctly rated fuse/s only) if it fails again, it may be that a boiler component fails during operation i.e. pump, fan, PCB etc. If during boiler operation the fuse/s do fail, observe at what point during the sequence failure occurred, this will give an indication as to the possible component causing fuse/s failure.
Upon completion of the fault diagnostics carry out final electrical safety tests and checks as per TOPs (C6).
