It was a great challenge sorting this machine and was a chance to put my skills and patience to the test. It was a nightmare stripping it down as it was in a hell of a state. The waste tank had 10 inches of sludge (solid) in the bottom and the auto pump out was solid with sludge but nothing a good clean didn't sort and to my suprise the auto pump out still worked.
I have also sourced all manuals, wiring diagrams water flow diagrams and complete break down drawings of entire machine and all parts. (A massive thank you to Chemspec Europe for help with that side of things).
