MY RINSE AID CAP WAS MISSING
I ORDERED THE PART THAT WAS EASY BUT WHILE THE MACHINE WAS USED FOR HOW LONG I DON'T KNOW WITH OUT THE CAP IT GOT FILLED WITH FOOD AND JUNK. FIRST THING I HAD TO DO WAS EXAMIN THE DOOR AS TO HOW I COULD CLEAN THIS THING OUT. I REMOVED 6 SCREWS THAT HELD THE DOOR TOGETHER AND PULLED EASY CAUSE I DIDN'T KNOW WHAT I WAS GETTING INTO. NO PROBLEM THERE WAS NO ELECTRIC PLUGS HOOKED TO THE DOOR. I TOOK IT OUT SIDE AND STARTED USING VINIGAR AND POURING IT INTO THE HOLE AND SHAKING THEN TRYING TO GET IT BACK OUT. WELL THERE IS ONLY ONE POSITION THAT WILL LET THE VINEGAR BACK OUT. I HAD TO HOLD IT SIDEWAYS THEN TILT FORWARD AND IT WOULD RUN OUT AND BRING SOME JUNK WITH IT. THIS WAS A TIME CONSUMING PROCESS BEING YOU COULD NOT SEE INSIDE TO KNOW HOW MUCH JUNK WAS IN THERE. JUST POUR AND DUMP. AND DON'T FOR GET TO SHAKE TO LOOSEN ANY THING LEFT INSIDE.LOL I WAS VERY PROUD OF MYSELF NOT KNOWING FOR SURE IF I FIXED IT OR NOT BUT I TOOK A SHOT I HAD. I DID SOME SCRUBBING AND DEGREASING ON THE UNDERSIDE OF THE BOTTOM OF THE DOOR BEFORE I REASSEMBLED IT. THAT WAS EASY AND I CROSSED MY FINGERS ANY WAY. I GOT OUT MY NEW PART AND THE JET DRY I BOUGHT AND STATED TO FILL THE DISPENSER AND IT TOOK HALF THE BOTTLE.YEA !!! I PUT THE CAP ON AND COULDN'T WAIT TO DO A LOAD OF DISHES. EVERY THING IS LOOKING GOOD NOW. THANK YOU PART SELECT FOR MAKING GETTING THE PARTS I NEEDED SO EASY AND SHOWING DIAGRAMS SO I HAD THE RIGHT PART. I COULDN'T HAVE DONE IT WITH OUT YOU.

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.

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.

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.

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.
