The picture is of the 1952 model
Lots of changes in two years. From the February, 1952, issue of Electrical Merchandising:
Selling Features: A built-in 4 gal. Fiberglas water heater tank makes it completely independent of home hot water supply; provides a 190 deg. F rinse; universal inlet hose does not have to be fastened to faucet during cycle, eliminating need for a permanent faucet connection and freeing faucet for other use during cycle; does not require installation or special plumbing; when necessary it can heat its cold water to the predetermined temperature making it ideal for summer cottages, trailers, canps and on boats where hot water is not available.
Other features include a temperature-controlled start, automatic lid opening, push button starting and a new spring-mounted centrifugal water circulating pump; built-in safety features include a safety float switch which does not turn on the 1250 watt immersion heater unless there is water in the tank, and a lid safety switch which shuts off circulating pump if lid is opened at any time the pump is running. First rinse is at 165 degs. F; for 2nd rinse the temperature of water rises to 190 degs. F.
Easy to operate; universal rubber faucet connector attaches to hot water faucet, dishes loaded while washer is filling and detergent added. Hose is then removed from faucet and drain hose hooked over sink edge. If faucet water is not up to 140 degs. F, the pump will not start. When tub light comes on, pump starts. 15-min. washing cycle includes a 4 1/2 minute wash and two rinses.
