WH PORTABLE DW
Hi Paul glad you got this unique dishwasher it diffidently wasn't used much, looking at the motor and pump really brings back memories I won't say what kind. The motor is supposed to run the whole cycle, that foam duct is to expel the moisture from the dishes and al the heat from the very inefficient main motor, you will also notice a soft black rubber tube running up the right side of the that connects to the blower housing. This tube is used to pull hot air out of the wash chamber and thus give the machine forced air drying. None of these DWs had wheels on the racks but yours actually has a detergent dispenser the builder models just had an open cup on the door with no lid it was divided in two sections and said 1 and 2 in the same open cup. That machine would go right into a 30 minute heated wash and then 5 rinses , the motor never shuts off, in fact most of these used a clothes dryer type timer that advances continuously and can be turned in both directions by the user. You may have the only surviving one of these out there, they also made high models of these but I don't think many were sold as it wouldn't compare well to just about any other machine at the time. Just the lack of wheels on the racks no filter and no upper wash arm for the top rack did it in for most buyers. It was sort of a shame as the last WH DW design with the rectangular filter had been such a good performer it was actually check rated in CRs along with a KDI-15 and a WP machine it still wasn't very durable however. One of my secretaries had three of these she bought the first because of CRs rating but the next two because she liked the local dealer and the fact she didn't have to buy new front panels for the next two they used to be extra cost items on build in machines. In all she went through three WHs in about 12 years and then I installed a WP about 1982 which was still working when they sold the house two years ago.
