My grandmother had the 606 and it had 3 temp selector hot,warm and cold. I think that the warm and cold had cold rinses. The hot was a warm rinse. 2 speed select Regular and Gentle. And 4 water levels...small ,medium,normal,and Large. Cycles were Regular wash and a Soak Cycle and Perm Press. Hers had the metal cycle control knob and the pilot light. She had the matching dryer. Halo of Heat with Electronic control. One knob did it all. They were a nice set and were still running when she passed away back in 2001. She didnt use the dryer much since she hung mostly everything outside when it was nice out. My cousin has the dryer now and its still going. The washer I think was donated and that was still running flawlessly.
That set is what I learned on when my grandmother taught me to do laundry. Oh the memories.
