The 1978 Kenmore 70 that I grew up with also was a Sud-Saver Model.
When I used the machine (whether it was doing my own laundry in that machine or doing the family’s laundry when my mom wasn’t doing it), when I was washing lightly soiled clothes, I used the S-S feature to conserve water and detergent, and when the machine was finished drawing the water back into the tub, all it did was add fresh water to the tub to bring the water level back up to where it is supposed to be, and all I did was either add JUST a little bit more detergent when it started agitating or didn’t add any more at all, depending what my judgement call was.
But to draw the water back into the machine, all I had to do was advance the timer to “Suds”. By default, if I am doing a normal load of clothes, I would just leave it alone, it will advance to the wash cycle on its own. Now if I want to drain the water out of the machine, then I would stop the machine and advance the timer to the Permanent Press cycle, and the water will go down the drainpipe.
On the 1969 Lady Kenmore that’s in today’s POD, same thing, just advance the timer to “Suds”.
But didn’t the earlier push-button WP’s/LK’s have a push-button that also enabled this very feature? I know I saw that on the 1965 Lady Kenmore.
