Most of the dishwashers I have pulled apart are Stainless Steel lined. Mostly Fisher & Paykel, a NZ brand.
Easyish work, nice easy to remove pump motor, 3 hoses with thick wire clamps and 2 screws holding it in place, Plastic housing held in by a 'K' (Bayonet) mount.
Two solienoids= Copper wire 50gms.
Plastic coated wire, small plastic control panel and some plastic plumbing inside.
Some Lint insulation and a some thin panels of Tar pitch stuck to the outside of the liner, bash inside and it falls off.
The electronic control box, save then as they do have connection problems inside so if its got a smudge of smoke, thats why it stopped going.
The spinner arms are stainless, they wear on the mounting face, sometimes right thru, so if it has a loose spinner arm, thats why that one stopped working....
Door liners Stainless, so that goes with the inside liner of Stainless and the filter screen and spin arms and that equals 10+ Kg of 'Stainless'.

The door front and outside casing is enamel white sheet steel. I cut a door up last week and used 1/2 of it to replace a rusted out sill on my car. Nice :-)
