What kind of "an idiot" never tries to use a dishwas
Oh, I don't know...maybe someone who can't figure out how to turn it on and don't want to experiment to try to "get" it? I see nothing that is clearly a control knob or control sliders/buttons anywhere. The one thing that looks like it might be a control knob (to the right of the lever [handle]) is rather small and it probably isn't clearly marked as such. The lever [handle]? It probably just locks and unlocks the door and gives a grip.
The thing I can't figure out? Why would someone who has such a rare item for sale in such good condition would take a picture and NOT:
1.) Get the focus and lighting right (even a cheap digital camera can take a good enough picture if one does it right);
or,
2.) Pick up before the picture is taken. Buyers don't want to see one's dirty dishes--or even clean ones--piled up all over the thing.
Appearances do count, even on Craigslist.
