These truly sophisticated Lady K washer models were made from 1966 to 1975. Over these years, the button selection labels changed amidst the added features including soak (1969) and knit (1971) cycles.
The selections were as follows from left to right, top to bottom row: PRE-WASH AND...
Whirlpool Cool-Down Knit Cycle
It was about 1973 when Whirlpool added the KNIT cycle with the 1-phase cool-down, as opposed to the 2-phase in PERMANENT PRESS and no cool-down in GENTLE.
Cool-Down Knit Cycle
It was either 1972 or '73 when WP added the Knit cycle with the single-stage cool-down, as opposed to Permanent Press's double-stage cd and Gentle's lack of it.
1-18 Frigidaire Permanent Press
If the 1-18's were set on the Permanent Press cycle with the speed switch on high/high, you would still get a low speed spin, a major plus in my personal opinion.
WP/KM lack of spin-drain
One other question I have regarding classic Kenmores and Whirlpools is why they weren't manufactured to spin-drain. Putting them in spin with water in the tub would hurt the motors.
