Upper Spray Manifold

I wanted to get the dishwasher cleaning better and thought that maybe the accumulator needed to be replaced. I figured that I'd swap out all the spray arms as well, just for good measure.

I needed Torx screwdrivers (T15 and T20, I think - not 100% sure on that) and patience because there's really quite a lot of screws to get the accumulator out. Finally got to it and it didn't look damaged, but replaced it anyway.

The spray arms are easy - they just snap in except for the lowest one, that had a plastic nut. I ordered a replacement nut just in case I broke this one (you know how that goes) taking it off. Well, it took pliers, but it came off ok.

In the end, my dishwasher is happy and cleans much better now.

I know that I have very hard water, but am reluctant to get a softener. I hope that changing the "guts" of the water delivery to my dishwasher will help...already replaced the filters which helped too... so far, it's a little better.

Installation was a breeze. Took off the upper, middle and lower spray arms. Had to loosen screws in filter assembly to remove old manifold. Popped everything into place... had to scrape mineral deposits off clips that support manifold and upper spray arms.
Easy...

now the dishes come out clean.

unsnapped the broken piece from the under side of the top rack; assembled new washer arm and snapped back in place under the top rack.
