1. Manually unscrewed the lower dishwasher sprayer from the base of the dishwasher. (The filter gasket cannot come out with this in the way.)

2. Using a nut driver, unscrewed the old plastic filter cage in the rear.

3. Thanks to a tip from another user on this site, I carefully pried up the metal grommets on the two plastic studs in the front. I did this slowly with a flathead screwdriver, as I was worried about breaking the plastic. (Some plastic did whittle off of the studs from the sharpness of the grommets, but not so much that they were ruined.) Note, the studs look like something that can be replaced if you break them. They are not molded into the tub, as far as I can tell.

4. Removed the old (rotten looking gasket). Be careful! The edges around the filter drain are sharp. Used a turkey baster to suck out water from the filter area and wiped away mildew. The filter recess had broken glass in it and some other yucky stuff.

5. Easily reversed process with the new gasket. The new one has a lighter color and has the plastic, upside down basket thingy built-in. (No sharp edges). I pushed the metal grommets back onto the plastic studs, working them down as tightly as possible. They seem to be holding well.

Piston and Nut Assembly for Check Valve:

I wasn't sure I needed this, but ordered it anyway after seeing comments that the seal can corrode.
Mine looked ok, apart from food build-up, but I replaced it anyways.

1. Removed the screened housing that covers the length of the bottom-rear using nut driver.

2. Unscrewed the existing valve manually. It was easy to do. Cleaned area out as best as I could.

3. Reversed process with the new part.
