Early 80s is not MCM
This was about the last gasp for D&M upper end DWs to wear the Kenmore badge
D&M KM DWs did more to harm the KM Appliance name than all other appliance problems put together for Sears, Sears took these machines back by the thousands and paid untold amounts of money out to cover the leaking damage these did to customers homes.
PS and yes that lower rack was not even deserving of being in a BOL DW let alone one that sold for almost as much as the basic Kitchenaid DW. That rack was a desperate attempt to reduce Sears cost of replacing lower racks where the ends of the tines rusted.
