Hotpoint always seemed to have more features than comparable GE models. Even though they were a subsidiary of General Electric, they had some autonomy in design. Their dishwashers were historically different and somewhat more advanced than GEs, at least through the early 60s. I believe that their ranges went to infinite controls before GE ranges. With their Customline of kitchen built ins, they offered many more choices than GE. They had water dryers and GE never did except for the combo. Speaking of combos, the Hotpoint combo was such a successful machine that it infringed on so many of the AVCO/Bendix patents that they were all taken out of service and destroyed to settle the suit. It must have been cheaper to destroy them than pay the royalties. Needless to say the Hotpoint combo was a far better attempt than the GE. GE washers had the mini basket, but only Hotpoint had the small tub on the agitator that had its own water supply so that you could wash in two different temperatures. You could even use bleach in one tub and wash colors in the other because the water did not mix, not even during the drain.
Everything Greg said about the giant dryer is true; sad, but true. Another thing about the dryers that came out of the Chicago factory was that every wire was yellow -- terrible for service people.
A coin laundry in the Peachtree Hills area of Atlanta had some Hotpoint machines with a sort of chunky agitator that was a dark burgundy color. One time a friend of mine took his laundry there and I guess the big old queen thought she was Julia Child and decided to alternate layers of laundry and powder detergent. When the machines finished doing what they did, the detergent was still undissolved between the layers of clothes.
The 1967 pair in the picture showed the infinite speed washer. Several brands tried them in 1967 and they shared a fatal flaw: the infinite speed mechanism did not last. Most used a magnetic clutch. I briefly used a Frigidaire with this feature and it was fine for one cycle, but if you set it for an extra rinse, the very warm magnetic clutch did not transmit enough power to even completely empty the solid tub in the final spin.
