GE dishwashers that had an aux pump on the sump were able to go from 3 to two final rinses and reduce the number of prewashes for the same cycle.
Interestingly, when GE went from their plastisol to their permtuff models reducing the size of the sump (in comparison) they went from 3 final rinses at about 2.5 gallons per charge to two rinses at 1.8 gallons per charge. However, that did not prove to be enough as they went back to 3 rinses in the latter 80s- one 1.3 gallon and two 1.75 gallon charges.
In the 90s they reduced the size of the sump boot and pump body again going to 3, 1.3 gallon final rinses.

Had a dual-pump design starting in 2000. It was their tall tub dishwashers.

Yup, I guess to mimic the EU design?

done it. Cheaper, lighter, quieter, supposedly more efficient. Easy to change a failed drain pump, and if the wash motor/pump is a side mount or below tub mounting witha wide hose between, that too.
