Hi I have a Heatrae Sadia multipoint 50 that has been working perfectly for the last 3 years but has recently started blowing fuses in the fused spur that it is wired into. As I said it has been working with no problems but since it has blown fuses I have changed them and it has continued to heat water for a while (maybe an hour or so) and then blown another fuse. Help please.
Regards Rob.
