Fast post.
I reinstalled it myself and it was really simple.
Fiddly? A little but once you unscrew all the screws and pull it apart it's a simple mechanical system that doesn't require any expertise.
Definitely not worth paying to have it done.
I'd say it took me 15 mins to dismantle (because I had to take time to navigate what was next) and leas than 10 to put back together.
Was pleased to see the inside of the machine was in great condition with no signs of burnout even after plenty of use.
Very happy!!
