D&M Built DWs
My 8th grade algebra teacher [ who loved her KM washer and dryer ] said she loved to hang around dishwasher sales area in her local Sears store and when she saw someone looking at a KM DW she would go over and whisper get a Kitchen-aid DW, LOL.
Our family also bought our first DW from Sears in 1966, we were having Sears remodel our kitchen and my father and I both pushed for the MOL KM 600 built-in DW, my Mother and older brother both wanted to get a KDI-15 because of CRs rating and the fact most of my Aunts had KAs and liked them. My father did not believe in paying for overpriced brand names so the KM won out as the final selection.
Boy did I learn a lesson, the D&M DW while it did an OK job on dirty dishes [ we never rinsed anything as the instruction book said that it was not necessary ] the breakdowns started during the first year warranty. The DW had at least three warranty calls and by the time the machine reached its tenth year of life and I pulled it out and installed a three year old WP SAU-500 every part of the KM had either been replaced or rebuilt except the tank and the racks, even the inner door panel rusted so badly I replaced it.
The WP DW not only never had a problem it did a much better job and I have had WPs ever since. I also have two KAs a KDS-16 and a KDSS-20 and while these are beautifully built machines they both have design flaws that affect the performance that the WPs do not have. The biggest problems with the KAs are messy [ stinky ] filters poor drying [ especially if used on energy saver dry ] and the lack of real water heating with the pump running where the water gets to a guaranteed temperature during the main wash and final rinse. As a service person I have always found KA DWs to be a lot more fussy and a little more repair prone than WPs, GEs as they are so much more complicated that they often needed a little help.
