not getting dishes cleaned

Seemed like I was getting more food stuck on my dishes than cleaned off. Because I've had this problem before, I already knew how to remove the lower spray arm and take off the large white housing beneath the spray arm with a special nut driver (shaped like a star) to get at the parts inside. The white plastic filter that circles the lower sprayer center was totally clogged and bent out of shape and was preventing the spray arm from turning. The microfilters built into the large white housing part that I removed using the special driver were also clogged from years of use. I cleaned the microfilters by agitation in water with lots of vinegar, poked the calcium deposits out of the holes that were clogged in the lower spray arm, and put the whole thing back together with the new plastic filter I bought from this site. Works like new again.
