1. Remove both upper and lower dish trays
2. Remove the “Spinner /Sprayer” (small nut on the top)
3. Unclip the “Tower” from the top and rear clip
4. Remove the “Tower” from the unit
5. Remove the “Filter Guard” on the bottom by removing 3 torx screws
6. Remove the “Discharge Housing” & “Impeller” (1 – 15 torx screw)
7. Remove and replace the “Accumulator Filter” (8 – 20 torx screws)
8. Assemble in reverse order

After disassembling accumulator assembly looking for reasons that washer not washing properly, I noticed accumulator filter had failed. The plastic (or whatever material it is) covering the holes was torn in a couple of different holes. Realizing that this was not the reason for the loss of pressure I investigated a little more and found that water arm going into the docking station was extremely worn with much play. Water pressure was compromised because of it. I replaced filter and docking station and now its like a new dishwasher again. Saved a dishwasher from the landfill!

Went fine..video made it easy..one of the best instructional

Unfortunately, my experience was unlike that of the other people who posted. While everything did go back together it was very difficult to get it all to press down tightly enough to tighten each set of screws. The project took about 2.5 hrs and I still don't think it is exactly right. I'm still going to have a professional out to finish the job. Also, the tool needed to complete the job was nothing fancy, but also not in everyone's home tool kit.

Accumulator was as easy as just removing srews and replacing the part. The Float I broke by accident and was more complicated to replace required 2 people to manage parts.
Dishes finally coming out clean!

also had to replace heating element. Had to remove dishwasher from under counter to get to heat element. Initial installer used long braided steel water line and plug in electrical connection so removal was easy (10 min). Pulled (2) electrical terminals from heat element and (2) plastic retaining nuts put in new element w/matching nuts,element came w/seals. Check for leaks before installing back under counter. Then removed torx screws holding impeller cover and accumulator/filter removed old put in new after good cleaning of course. All is well.

with dishwasher running I would open the door and notice the lower spray arm was not turning. I removed all parts in the tub and clean off all the accumulated gunk (likely combination of food and soap scum - like a white paste) . The accumulator screens where more than 50% clogged with no way to clean the inside. I replaced the accumulator part and the lower spray arm because 2 holes had gunk in them that would not come out. dishes are now getting clean and I am switching to liquid - no more powder as I suspect it caused the build up over time.

By reading online about some similar problems, I discovered that the accumulator did, in fact, have some holes worn through the screen and was leaking sediment back into the rinse water. After waiting for 2-3 months because the apart was on back-order at the factory, it took me less that 1 hour to remember how the unit went together (reviewed the parts diagram online) and connect everything up. On the first rinse, the dishes were really clean - well worth the wait. Doing dished by hand reminded me of the old days....

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.

There was a tear in the fine filter (fabric) on the accumulator. This can be seen by looking in dishwasher without having to disassemble anything. Food was being sucked in and sprayed back out on dishes.

Disassembled, cleaned, replaced part then reassembled.

Cleaned out the spinning sprayers -- used toothpicks to clean out holes, flushed with water.

Cleaned out under the accumulator.

Works like new.
