My glowworm micron 70ff boiler has stopped working today. The 3amp fuse in the spur had blown so i changed that but it still wont fire up. There is power getting to the boiler and the internal fuse hasn't blown.
Anyone got any ideas what could be wrong with it?

surprised the quick blow hasn't blown????
general fuse blowing parts are working parts eg fan pump valve
