I have an S10...I believe they were made in 1988....Most of the parts are still available through Mocopan or Coffee Parts, though beware if the touch pads dont work, as they are unobtainable anywhere!
The machine normally needs to be plumbed in, and should have an external pump/electric motor module. Mains water goes via a filter into the pump...
I currently have mine running in my workshop from a 20 litre tank with water pumped to the machines pump via a Flojet pump.
I am in the process of restoring mine, and it seems to be a very well built, heavy duty steaming monster....probably a bit big for the kitchen, unless you have either an understanding partner, or a very large kitchen.. :-?
