My issue is that my machine doesn't follow any of the wiring diagrams for my model. Live where neutral should be, terminals labelled differently to the diagram, wires coloured differently to both the diagram and UK standards. It's been a lot of fun...
Yeah, this was my totally my experience too and definitely the hardest part of the build. Think our units were made on a Friday afternoon after a liquid lunch at the pub.
Can't speak for anyone else's experience but I followed the wiring diagram and I've had no problems 12 months on.
