Early Kenmore Dishwasher Owners Manual - Releases
I'm guessing this book is from around 1956. This is probably the first front-loading home dishwasher ever marketed by Kenmore. It's made by D&M. The dishwasher in the earlier Sears catalogs was marketed under the name Homart as a top-loading machine.
Full operating instructions, cycle chart, installation instructions and parts list included.
