Pump Fuse 3A Blowing?
Have an issue where the 3A fuse on the socket that feeds the pump and heating controller unit keeps blowing when the boiler kicks in. Pump replaced for brand new Grundfos 2 weeks ago - its the right way up, etc. Have some rust and larger iron oxide lumps in the system, but have removed pump and rinsed through to remove detritus.
Have cut and re-terminated the electrical connections from mains to pump, as well as using hair dryer to ensure no water ingress.
Running out of ideas....Any help appreciated?
