Water dripped out from the bottom of door.
Diagnosing the problem, i.e. finding the source of the leak, was the hardest part. The best clue was the leak only occurred well into the cycle when the water was hot and steam was coming out the vent. I then assumed there was a bad seal and steam & condensed water was leaking down into the door. I replaced the vent duct & seal, a broken drip cover (an internal part in the door), and replaced a missing rinse aid cap. This stopped the leak.

soap lid missing
Replacing the pin with the spring is a little tricky, it was hard to hold it. And the little plastic pin breaks real easy too, its hard to get the lid to snap in place without breaking the pin.

Upper spray arm mount cracked and rinse aid cap broke
Unlatch the rail clips on upper rack slides, slide rack off the rails. Flip rack upside down, use a philip screwdriver and remove screw that holds propeller to upper spray arm mount. Remove clamp of broken spray arm mount with philip screw driver. Replace with new upper spray arm mount (different design) and no tools needed. Just snap it in place where old one was. Put propeller over the spray arm mount and reuse screw with washer to tighten. Return rack back in the dishwasher and reattach the rail clips. For the rinse aid cap, the cap broke off. I used a nose plier to remove (unscrew) the remaining piece. Replace with new rinse aid cap. Dishwasher is running normal again.

The hose that connected to the middle spray arm was worn and had deteriorated
Easily installed the hose and replaced the middle spray arm with the help of my brother the savior! Lol. It was very easy for him to install.

Wash arm retainer nut snapped in half
First I pulled the top half of the broken retainer nut out of the lower wash arm assembly. Then I took the was arm assembly off, removed the other half of the screw, set the lower spray arm seal into the lower wash arm assembly and screwed the wash arm retainer nut back in. As a bonus, I decided to replace the broken Wet agent cap. Had to use needle nose pliers to unscrew the broken bottom stuck in the well... That was the toughest part and it wasn't critical to the dishwasher functioning.
