Great brochure, Steve, thanks!
The "Extra-Action" controls give you a Normal wash with five rinses. +/- 3 gallons for each, 18.5 total. I'll bet "RInse and Dry" is two fills/rinses.
I had a tad earlier portable BOL Westinghouse for a couple of years, passed it on to a couple of friends before losing track of it. One-dial-wonder, avocado green, but did have the Radiant Rinse Jet Dry dispenser and covered-auto dispenser for two washes. It actually was a good performer overall, nobody ever complained. I'm sure it was a thirsty piggie, but we had plenty of water back then, rationing hadn't yet started.
