70061
We still have the 70061 at my grandparent's old house. It's almost rusted to death in the sump, but still plugging along. The only repair it's needed was a new drying fan, which Roger and I pilfered from a donor unit when I was still in Tucson. The old fan was getting squally when it ran.
In terms of dishwashers, I've used better, and I've used worse. The BOL GE from 1975 made handwashing seem viable, and could dirty load of clean dishes with no food present in the machine, so (*volley*) you can keep it, Bob ;-) Would I toss the KitchenAid for this? Hell to the no. But if stranded on a desert island and left only with a 1980 D&M, I'd get by. (If I had that GE, I'd be off doing dishes in the coral reef.)
This machine did fine with normal soil, but we never used the Water Miser button--just Power Miser, and with fan-forced dry and the bone-dry Yuma, Arizona air, it was a non-issue. The multi-level wash worked well, although chunks of food would frequently clog the wash-arm holes, making a tweezers a necessary part of any Kenmore owner's toolkit. The pressure of water emitted from the nozzles was incredible (thus requiring careful anchoring of items--and the sound of a plate banging away in the bottom rack with each sweep of the wash-arm was a constant irritation and frequent issue), and the machine could scour soil from any surface--the only problem was whether there were enough water changes to serially dilute and exhaust the particles down the drain before it reached the dry cycle. Greg and I once had a bet on throwing a whole pot of rice, or tray of potatoes au gratin, into a D&M--and letting it go through a heated dry--and it still makes me chuckle to this day ;-).
If you don't have a soil separator (and a good one) on your machine, it just doesn't work. You need a filter or a soil module to keep yiblets out of circulation. Pots and Pans was a viable cycle on these due to pure serial dilution; the Sani Wash/Rinse was a nice feature, too, but used indiscriminately, it served more to bake stuff on than scour it off.
