MAYTAG SO CALLED TIMED BLEACH DISPENSER
The bleach is pored into the dispenser as the washer is loaded and as the washer tub is filling with water, water also fills the rest of the bleach reservoir. This system does a very good job of keeping the bleach away from the clothing and diluting the bleach. As soon as agitation begins the diluted bleach is slowly being mixed with the wash water. When I first had one of these washers with this dispenser [ A900S ] we put blueing in the dispenser to watch it work and all the blueing was mixed in the water within one minute after the start of agitation.
All in all it was a very clever way to dilute the bleach, but the bleach still goes in way too soon for best cleaning and whiting of the clothing with minimal fabric damage. Bleach should go in much closer to the end of the wash period, as almost all good machines do now and even back then.
