the first time it did it when the timer kicked in and blew the internal fast blow 2 amp fuse, the 3 amp fuse in the wall switch and tripped the fuse box. but after replacing them and starting it up again it was just the 2 amp internal one that went.
hello, please could someone help!
our boiler has just started to play up. when you turn on the heating via the timer it blows the fuses in the boiler. is it the timer that needs replacing or what else could it be further up the system? and how would we be able to tell??
hot water works fine...
