The 1965 WH was inspired by the KD12 down to the large rectangular filter, but with detergent dispenser and longer wash cycle for great cleaning. It was a powerful machine, but was changed and cheapened. The WH dishwashers with the Roll Out Washwell remained farily primitive machines without detergent dispensers long after others had them. Interestingly, WH was the last DW manufacturer to abandon their impeller wash action for a pump-supplied wash arm. Even in the mid 60s, WH offered their roll-out which looked very modern with no decorative markings on the front, just the small timer knob. Around 1954, the model that Robert has with the white rectangular handle on the drawer front had a metal impeller, instead of the previously used Bakelite, which gave exceptional washing results, but the impellers reverted to Bakelite in subsequent years. When WH came out with the water temp booster which guaranteed a 140F wash, they were in the vanguard of heating wash water once it was in the tank and ensuring the high temp with a timer delay while heating. What Westinghouse did not advertise was that the heating could extend the cycle to 90 minutes with a 600 watt heater in an uninsulated tub with no prewash because the first models with this feature did not have a prewash or rinse due to lack of a detergent dispenser. It was dynamic water heating with the motor running so the dishes were scrubbed every minute of the time the water was being heated.
