Jerome, I am with you. Especially the VMWs, which are absurdly slow.
I am guessing the 4.4 gallon per minute flow restrictor is because of the normal eco cycle. On normal eco, at least the EM models, only filled for 24 seconds with hot water in the wash period, and did 3 24 second cold spray rinses only.
So, 4.4 divided by 60 = 0.0733333 gallons per second.
24 seconds x 3 sprays = 72 seconds
72 seconds times 0.0733333 gallons per second = 5.28 gallons of rinse water total. No thank you.
What is interesting, Whirlpool resource saver spray rinse service manual says that each recirculation spray uses one to two gallons of water. There were six recirculation rinses on the original resource savers.
Whirlpool Resource saver uses between 6 and 12 gallons of water, and adjusts for the amount of clothing in the basket.
