Leaking
I first made a bad assumption that the leaking dishwasher was from the gasket. I replaced the gasket and it still leaked. To find the leak, I took the body off of the dishwasher and ran it to find the leak. It was from the solonoid connection. I took photos of the leaking motor unit and very easily replaced the new motor unit by matching the placement from the photos. The hardest part is tipping the dishwasher on its side and mopping up the water. It was very easy. All you need is a nut driver and a Phillips screwdriver. Even an over-domesticated, non- tool user can do it.
The wheels kept falling off the lower carriage in our dishwasher.
Each replacement wheel came in two parts: the wheel itself and the clip which had to be pushed through the center hole in the wheel in order to attach each wheel to the carriage that holds dishes. I had difficulty assembling the clips and wheels until I ran the clips under hot water to soften them. This made it possible to assemble the wheels and attach them to the dish carriage. I would have preferred the wheels to have come assembled, particularly given the price of each one.
The new rollers snapped into place on the rack, by simply pushing them in. I was able to do it by hand, my wife could not do the same, so you might use some pliers.
easiest way i found to do it was pull dishwashers out from under the cabnet... laided a pillow down in front of the door and turned it on the front side... the part was very easy to get to at this angle....could have done it in less then 5 minutes but took my time to double check everything to be safe....took a total of about 10 minutes..... very happy now no longer need to vacume out the old dish water left at the bottom of the dishwasher...... i think most anyone could do this very easy....
Pulled washer out about 6" without disconnecting any hoses. This way i could use both hands from the left side & front after i took the kick plate off.
I removed screws holding the rollers to the side of the dishwasher. I pried the end caps from the slide. I removed the broken part from the upper rack. I then replaced the broken rack roller, inserted into the slide and screwed the rollers which hold the slide into the sides of the dishwasher.
Removed screws on the drain pump filter screens at the back of the dishwasher, unscrewed the check valve, screwed in the replacement unit, and re-affixed the filter screens.
I lived with the drain problem for 6 months and reviewed on line trouble shooting which all pointed me to a pump or solenoid valve problem. I pulled the unit and disassembled everything before noticing that the rubber washer/stopper at the top of the check valve had erroded away and was not preventing water from pumping back into the cabinet when the drain pump kicked on. Always check the condition of this check valve first if you dishwasher is not draining properly. It was so easy once I found the bad part.
