The overflow rinse is no joke on these machines. My WCI-63 will rinse for five minutes! My water pressue is so strong here it must change the water in the tub twice before it goes into final spin.
As for Rapidry--------NOT! But its as good as a Maytag so no problem.
IMO the best of both worlds is to take a WCI-66 (that really does have a Rapidry) as shown in a previous thread, and replace the Deep-Action Agitator with a Three-Ring from a '63 or '64. Now THAT is a powerful machine!
