2 Speed WP Portable DW
Nice find Robert, we have the exact machine in the DW wall at the Museum, I wish I knew that you wanted a white version of this DW I would have liked to trade front panels to get rid of our white panels for a nice set of shaded colored panels.
I found our DW brand new never used at a house that was being cleaned out, it still had all the samples inside etc.
The low speed gentile wash had a solenoid valve that allowed air to enter the main pump housing causing the washer to aerate and thus greatly reducing the water pressure. On our SAU500 1975 WP DW my Mom could wash plastic cups in the top rack without flipping them over, so it probably worked very well with light weight glass ware.
Overall these were great performing DWs, they were completely designed and built by Whirlpool, unfortunately durability of several major parts were not that great and partly because they would wash the chrome off a trailer hitch they also tended to destroy them selves more quickly compared to DWs like a KA witch did not even have a water heating element.
