yes, it did shake the house
We had the ElectricSink version of the one in the commercial in a related link. It DID shake the house. Steam billowed out the vent ridges on top of the door during the entire cycle. Gravity drain connected to a "Y" in the basement that also drained the kitchen sink. Mother did pre-wash, but probably didn't need to. One thing you didn't do with this one: wash Tupperware in it. Seemed to handle other plastics well, but Tupperware always became a blob on the bottom of the wash tank. About the loaded upper rack being too heavy to lift: ours also had a removable section of the upper rack, very small, that could be removed to load the lower rack instead of taking the whole rack out. And picture this: when the fridge and stove died and were replaced by avocado green ones, the "perfectly good, why buy a new one?" dishwasher was simply painted to match. Shows how generations have changed...now most folks (except us) rip out the whole kitchen if one item goes bad. 'cuse me for rambling...lol.... but this thread sure brought back some good childhood memories. and btw....i still live in the same house...a mid-20th century flat roofed ranch...if I ever figure out how to do pics on this site, I'll share some....my whole neighborhood is mostly still original, and many of the original owners still live here..
