Well , well ......
Ya learn something new every day. I had always thought that the bowtie builtins were like their predecessors as far as the drains
were concerned, from the bottom of the machine to an air gap fitting mounted on the counter. A small amount of flexible hose does the job ,
until it gets hardened with age. The new design probably solved an occasionally annoying failure. I thought the top spray plumbing would have been easier to accomplish with the limited range of movement of the cabinet housed lid. I bet your SU-70V " kicked ass " ; simply
load, add detergent , close , move the lever to lock , select the desired custom cycle and slightly rotate the timer dial to " power rinse " .....!!!
Time for " Man from UNCLE " .
