Wiring diagram/cycle chart
This is from model LSA9920 (1968). You can see the increments for Drain/Fill & then Fill/Agitate.
All WP & KM washers used this sequence from 1967 until about 1975/76 when it changed to reduce water consumption. At that time WP (& other manufacturers) must have realized the trending change in consumer behavior towards these fabrics, combined with the realization that the Dryer did most of the work getting out the wrinkles (as we've all said), and thus determined that reducing the water consumption would not affect perceived performance. The cycle became more of a "gimmick" selling feature (e.g. which manufacturer wanted to be the first to omit it entirely?).
