Have just visited the father-in-law and he asked me to look at his CH programmer which was dead. So was the power to the boiler.
I replaced the fuse in the spur and all the power lights and programmer came back on.
As soon as I call for heat or DHW the fuse blows.
Anyone got an idea on where to start to look for the fault?
Regards
