Water was not draining out.
First I disconnected the dishwasher, then I disconnected the drain hose. I pulled the machine from under the counter and turned it on its side, so that I could see where the drain pump was. I removed the two screws that hold the element in place. I then pulled the pump out and disconnected the two wires. I took a good look where each wire was attached. I also had to disconnect the pump from two small hoses. I installed the new pump, I had ordered from PartSelect, following the reverse procedure. I reconnected the dishwasher and slided back under the counter. I confess I didn't believe it would work. I was prepared for failure. The machine started, then when the cycle changed, I heard the water draining into the waist pipe under the sink. New hot water filled the machine. Would this water be drained out and at the end, after the rinsing cycle, would the dishwasher be empty and completely free of water? I waited for the end of the rinsing, then I opened the door and checked for any water left at the bottom. Suddenly a feeling of joy and pride went through me. All water had been drained out by the new pump. I had repaired my dishwasher. I didn't have to throw this handsome and well made machine into the street. My kitchen sink was no longer full of glasses and dishes. I was washing all I had accumulated during the week. My kitchen became clean and organized just like before. At this point I took an oath: when my dishwasher would break down next time, I would repair it , even if its motor, the most expensive part, had to be replaced. I was going to do it with the help of the experts at PartSelect. Thanks guys for your help and for inspiring confidence in myself. I DID IT! What a great feeling!
Now I understand the feeling a doctor must experience when he brings back to life a dying patient.

Water leak behind kick-plate
Water had been dripping for quite some time causing the floor boards to warp and buckle causing the door to no longer align. Water drip could be seen coming from the motor area. Ordered the O rings and replaced. Get Motor & Pump schematic Pub to visualize how parts fit together. I recommend getting motor (~$90)which comes with O rings (~$50 for O rings alone) because, as it turns out, the leak was in motor. I will post repair process in separate posting.

The plastic door latch handle broke-off and fell into pieces.
Removed 6 screws, pulled the front cover forward, removed the old door latch, installed the new latch, replaced the screws, DONE! Took about 10 minutes. The new door latch works to open and close the door, and the dishwasher runs fine when the door is closed. However, the new door latch does not lock the door into place like the old one did. I didn't remove the screws and loor latch assembly again, but there must be a difference between the old part or the new part. And I noticed that the old part number and the part number of the replacement part are not the same, although the website indicated that it was the correct part for my model.

Heater Element Covered in Mineral Deposits
Our dishwasher sat in a warehouse for a year after our move from CA to TX. When I finally installed it, there was some sort of white mineral deposit that had built up on the heater element. I didn't notice it back in CA. I tried to get as much as possible off but it kept building. So I purchased a new heater element. It's been in for a few weeks and my wife thinks the build up is happening again.
To Repair;
Unscrew the dishwasher from the counter. They'll be one or two screws attaching the dishwasher on the underside of the counter.
Pull the washer out carefully.
Remove any dishes and the bottom rack.
Tilt washer on it's side.
Remove wire connections to heater element (They slide right off but make sure to remember which one goes where)
Unscrew the nuts that are holding the element on. I used some pliers. It wasn't difficult.
Remove old element and replace with new.
Reverse order.

Soap dispenser wouldn't open until the very end of the cycle
I'm a stay-at-home mom of 3 kids, so I enlisted the help of my oldest son (5 years old) for this job while the 2 little ones were asleep! First we cut the power to the dishwasher, then we removed the 2 bottom screws on the stainless steel front and slid it off to expose the back of the dispenser. We removed the red and white wires from the left side of the dispenser, took out the 6 screws holding the dispenser in place, put in the new dispenser, hooked up the red and white wires (in the right order), and flipped the breaker back on! We ran a cycle to make sure it worked, and it did!! My husband was thrilled! He thought for sure we needed a new dishwasher! :o) Thank you, PartSelect!

Broke nubs off of stem when cleaning
I took the bottom parts out. This can basically be done without tools. You need a phillips to unscrew 3 screws to remove the stem. Then easily replace with the new one. Putting the spiny washing part was kinda weird because I was afraid to break the nubs off again. I took the whole bottom carriage out so I could see better, pushed down kinda hard and twisted the right way (figure out which way needs to be twisted before hand by looking through the bottom of the stem).

easy as pie
First I shut off the power to the dishwasher from the breaker panel. Then I removed the five screws holding the plastic top panel to the door (on the frigidaire, there is no need to remove the entire stainless steel door panel). I removed each of the four wires from the old latch (pulling the wires off required some "oomph") one by one and plugged them into the corresponding position on the new one. I did this so I would be sure to have them in the right place. I used a torx screwdriver to remove the two screws holding the old latch. I then replaced the old latch with the new one, replaced the top panel of the door, turned the breaker back on and everything was as good as new! The whole operation took maybe 20 minutes. It couldn't have been easier. The only surprises were how difficult it was to pull the wires off and the fact that the screws holding the latch were torx head.

In future, when I need parts, I will definitely use PartSelect. I have gotten parts from other sources, and this is the first place where, along with the part, you get all this advice from other DIY'ers. It's an absolutely brilliant idea and a lot of help.

Bottom spray arm got stuck and melted
First I removed the bottom dish rack to gain access to the spray arm. I proceeded by pulling straight up on the bottom spray arm, it disconnected with gentle force. The replacement part was not identical, so I determined that it would work by inspecting hole patterns and heat shield configuration. Then I gently pushed the new spray arm onto the water supply tube making sure that the spray arm snapped into place. Due to extremely fast ground shipping (less than 20hrs from order to my door) the repair was done within 24 hrs! Boy...was my wife pleased!

dishwasher wasn't draining
I disconnected the power to the machine. Removed the bottom access panel and screws holding the dishwaher in the cabinet opening so I could carefully slide the dishwasher out.
Taking note of the pump position at the bottom of the dishwasher I removed the two wire leads, screws and hoses(pliers). I installed the new part in the reverse order and was able to run the dishwasher for a cycle while it was out to make sure there were no leaks.
Dishwasher runs great and the dishes seem cleaner. Fingers crossed.
Thanks.

dispenser cap latch broke
I foloowed the others who repared the same item. I really appreciated their help and input. The only thing I would add is when they said that you only have to remove the bottom 2 screws on the inside of the dishwasher door they are absolutely correct. But don't look on the very bottom of the door like I did. They are on the inside of the door, facing inside. The bottom screw on each side. Thanks for all the help.
