Right, I changed the brushes and after a bit of a struggle getting the
carbon on one to free itself I got the machine working. (Have only
checked it on spin as it was in my lunch hour and I was in a hurry!)

The only thing that worries me, is the amount of arcing inside the
motor on the high speed spin. It seems to be quite a lot and yes, it's
coming from the one that I had a problem freeing, however I'm pretty
sure it's free now.

Is this normal?
