Washing poorly, leaving particles of food on top of the dishes, not draining completely, ceiling spray arm not spinning (bent up to the ceiling)
The lower spray arm unscrews. From inside the dishwahser, put a screwdriver through the tab slots and unscrew the tower from the floor. It's pretty tight for plastic.
The upper spray arm has screws on the top of the dishwasher. You must slide the dishwasher out from underneath the countertop to get to the screws. Normally that's just the two screws above the door that screw into the countertop. Pull the insulation back and unscrew the arm from the top of the dishwasher. Reverse to reinstall.
Piston and nut assembly for check valve: Inside the dishwasher at the back there are 2 screws that hold a screen down. Remove the screen. Take out the check valve and replace it. It was still functional in mine, it looked like food gunk had built up on it and impeded the check valve action.
The flapper chec is a rubber flap in the drain tube that connects to your sink drain. You have to pull the dishwasher out from under the sink to get to the end of the drain tube that connects to the dishwasher. Take the hose clamp loose and remove the drain tube from the dishwasher. Then unscrew the plastic fitting that you just took the drain tube off of. The flapper chec is there. It had turned brittle and didn't flap anymore. It is a similar setup to the rubber seal at the end of your garden hose.
