Some advice will be appreciated. Got home and found the house cold. Check the boiler and controls and evertyhing was dead. I suspect the 3amp fuse had blown. Checked fuse which was blown and replaced. When I turned the 3amp plug back on it blew the 3amp fuse straight away. At the same time of this happening I noticed a small spark (short) coming from the pump capacitor wiring at the Grundfos pump. Checked wiring cannot find anything wrong. Now when I replace the fuse again the PCB fuse blows. And when I replace PCB fuse the 3amp fuse blows. Everytime I notice the short at the pump capacitor!! Could this be the pump capacitor blown or perhaps the PCB board? Your help would be appreciated.
