enjoyed looking at that manual
not sure what "models' it covers but i did see that it was referring to the old D&M brand machines that sears used to carry. i know they were around thru the mid eighties cause i put one in for a friend in 84. i also remember that at this time sears was starting to carry whirlpool brand with the sears logo as well.
i remember in the 60's and 70's all the sears dishwashers were the D&M's, the earlier ones using that unique top rotorack! used to look at em in the sears catalog and wish for one! what dreams may come!
