Note the lack of the separate rinse temperature switch.
The WP-made 33" wide combos had a sump that held 3 gallons of water to power the filter stream so, after the load was saturated, it only used 3 gallons of water for the wash. Since the water was not very well extracted, each rinse only used a little over 3 gallons of water. My friend's mother who had one of these used one little yellow cap of Wisk from the metal can to wash a full load. It did not over suds and I think the liquid detergent left the fabrics softer. Original Wisk had phosphates.
Today, many FL machines use even less water after the load is saturated and extract better between water changes. The big SQ FL uses about 3 gallons of water over what is required to saturate the load unless the water level is increased.
