The racks look somewhat reminicent of Fridgidaire. The design of the Spray Arms look somewhat like GE (except the jets are not wide enough if you know what I mean)  The pump definately looks GE'ish.... Humphhhhhh...... Still cute and yup the Magic Marker has to go.  Looks like a sign at the Market to alert something on sale.

Is probably the worst thing you can do to ANY DW, detergent and food oils help lubricate the seal and other vital parts of DWs. We have noticed that folks that per-rinse their dishes usually cut the life of the DW in half. Every thing needs to be done in moderation and with common sense, but no detergent can be as bad as too much, this is why you should always put some detergent in the first detergent cup when you run a full cycle in almost any DW.

I too was very fascinated when I first saw one of these DWs in a customers house back in the late 1970s and thought it would be very cool to have one. It was differently Made In Japan and as many of you have said it looks like they borrowed some design elements from GM built DWs of the time, and of coerce MWs DWs were being built by GM during the 1970s when this machine has built.

I finely found one of these rare machines in the 1980s and when I got a closer look at it [ It was also in pretty bad condition ] I scrapped it. It like many things Made In Japan in an earlier time was simply a copy of American technology done badly. But I do think that it is great you found one Peter and shared it with us as otherwise it may have been forever forgotten in the history of major appliances.

Thanks again for sharing this with us, great memories.
