Split Ring Seal

I unscrewed the top of the spinner, no tools required, and then I removed the spinner by lifting it up. Under that was a plastic nut that required a pear of pliers to loosen it then removed it with my fingers. The spinner assembly then lifted up and the seal ring was there. I replaced the ring and put it all back together, took maybe 20 minutes. I then replaced the wire racks with two new ones and now I have a new dishwasher. “Piece of cake.”
It has taken me longer to type this than do the repair.

This is the second time I've purchased parts from PartSelect.com. Actually called Lowe's parts hotline and got disconnected three times. Went online with PartSelect.com and purchased the items within 5 minutes. Parts arrived within 2 days. Will definitely be purchasing parts from PartSelect.com again when needed!!!

The problem is a worn seal ring. That ring is inside the lower spray arm's spray nozzle support assembly. The wash arm spins on that assembly.

I unscrewed the lower spray nozzle popup, from the wash arm support. That part, from which the extending spray nozzle rotator pops out, simply unscrews, by hand, from the wash arm support. Then I could lift off the wash arm itself to get it out of the way for the next step.

With the wash arm removed, I could then gently pry off the flat filter cover which was underneath the wash arm (the filter cover is simply clipped on. Use a screwdriver).

Now, reaching inside where the that popup spray nozzle was screwed on, you can see and/or feel a tall skinny plastic piece in the center of it, which actually screws that wash arm support onto, well, the rest of the dishwasher.

With that "screw" removed by hand, I removed the wash arm support.

Inside that wash arm support the old ring seal can be removed and the new one inserted.

Simply reverse the process to re-assemble.

Note that it's hard to determine where, exactly, to put that ring seal, inside the wash arm support. But it seemed to me it didn't really matter as long as it was just in there.

Exploded diagram was/is great - made it much easier to see what needed to be disassembled to clear clog (unfortunately i found this after the parts broke). Parts were eaasy to identify and select, delivered on time, and reasonably priced. All up, repair completely successful.

Appliance was extremely easy to troubleshoot and locating the needed parts were also, Thanks to Partselect.com
