Dishwasher door would hang open with no tension
My dishwasher is an under the counter mounted model. No need to pull it out or move it. I used a screwdriver to remove the casing on the bottom of dishwasher. I then removed another piece that was just behind this casing. When this was done I could see where the springs were on either side of machine right in the front, - easy access. I followed the directions that came with the part. Three simple pieces came in clear bag. You first put plastic red end onto end of long metal piece and put it through the spring. Hook it into place by catching one end of spring. I took notice of how broken springs were hanging in machine and then replaced the new spring. I hung one end of spring on the hook and then pushed other end with red plastic piece through to catch the notch. (You can adjust placement for door tension considering there are at least three notches.) Space was tight so I held onto free end of spring with needle nose pliers and pushed it through with my fingers to the notch. I almost called a repairman to do this for me. That would have been an expensive way out of an extremely easy repair. ANYONE can do this as long as they have finger dexterity. I am thrilled to have a perfectly functioning dishwasher door again. The parts were perfect and much cheaper than buying from Sears or elsewhere.

Leaking
I first changed the dispenser door latch grommet, which was very eazy except for the left side nut screw which was a little awkwaed to get to with the nut driver. Not a big problem but difficult enough that i stripped the threads (plastic) and had to get a larger screw which is working fine so far. Since the grommet didn't stop the leaking although it was obvious it was leaking from the soap trail. I ordered the gasket and got it very promptly put it on and guess what. Still leaked some. I discovered when they installed the dishwasher the door appeared to be warped. To fix this there are two door tension springs under the bottom panel. By adjusting these with a log screw driver problem finally solved.
It is good to have not only a great place to get parts but the idea's from others are terrific. Although this washer is 15 years old it looks new and now acts new. Thanks so much for good service and advise.

Coating on the rack has worn exposing the metal underneath
There were no instructions with the part, but looking at the old rack it was simple to see how the parts should be assembled. Took the center part from the old rack, twisted off, and applied it to the center of the new rack. Snapped on the wheels and was done. Very simple assembly.

Water leaking out the right side bottom of door.
Very easy to do. Used needle nose pliers just to get a first grip on the door gasket and then pulled it completely out. Pulled up the Water Deflectors by hand. Cleaned the gasket trough with a soft cloth, warm water and dishwashing detergent. Rinsed. Then simply pushed the gasket into the trough, lightly tapping into place, then pushed on the water deflectors, and no more leak!

First replaced rubber seal around door, which did not stop the leaking.
Then ordered insulation foam strip and replaced old one, which fixed problem. Put new strip over the old one because tub was slightly warped.
Very pleased with order speed and cost.

Rack was rusting.
Lifted out the old rack and set in the new one. The raised portion of the new rack was not high enough to clear the lower spray tower, so I adjusted the back wheel "axles" downward about 3/8" with pliers, which raised the rear of the rack enough to clear the tower.

spray arm would not spin
Even though there was plenty of water pressure from the pump, the lower arm would not spin. I could move it with my hand but there was too much friction for it to spin. Turns out an item named seal ring[38] (I would call it a slip ring) had become dislodged somehow at the interface between the rotating parts and the stationary parts but I did not learn that until I was able to disassemble it. I could see from the diagram that there were threads at the top of the SPRAY ARM SUPPORT[39] that engaged with the threads in the CENTER SPRAY NOZZLE EXTENSION[33] so I held the arm and tried to unscrew [33]. CRACK! The 4 thin plastic arms in [39] snapped right off. I then disassembled and found the dislodged seal ring[38]. I concluded that I would never have been able to disassemble without breaking [39] due to the calcium in the threads (even with repeated applications of vinegar or lime away): the plastic arms are just too wimpy. But the price of a new [39] was a bargain, I was amazed. Came in 2 days, I re-assembled, now the spray arm spins freely and the dishwasher works again. I will try to remember to use vinegar periodically incase the slip ring dislodges again. This has been a great dishwasher otherwise IMHO( and a bargain price).

leaking door
Removed the old gasket, without tools, and fit the new gasket into the space, making sure it was in the groove correctly all around, job done, works great. The ordering of the gasket on this site was easy and the shipping time was amazing, one day. Would use this company again, and recommend to anyone needing parts that wants to do repairs themself. I am sure saved a whole lot over hiring someone, and got the job done sooner also.

Broken door spring linage and lost spring
Took off bottom plate for access. Slid part that holds bottom of spring forward so I could reach it without pulling dishwasher out of position. Hooked spring to bottom attachment, then connected door spring linkage to holder that is attached to the dishwasher frame. Adjusted the tension with the tension screw and buttoned up bottom plate.

Water leak from the dishwasher door
After replacing the door gasket and seeing that this wasn't the problem, using the schematics found at partselect.com I finally realized that it may be the insulation foam strip. I ordered the product and received it very quickly. Installation went fairly quickly. It was easy to remove the old foam strip and install the new one. The only problem was that the foam strip was about 1/4 " too short and it didn't cover the entire bottom. I improvised a little bit and cut off some of the old strip and covered the gap. So far the leak seems to have been fixed. In addition to the foam strip I had to buy a torx screwdriver for $11 at the local hardware store. The total spent was around $25.

Left side Door Spring broken
First, I removed the 4 screws & Toe plate assembly below the door, exposing the undercarriage. The springs for both the right and left side are visible. Secondly, to help gain access to the springs (and for ease in reattaching the new sping to the appropriate tension bracket), I opened the dishwasher door and unscrewed the two small screws (located above the door) that secure the counter-top attach brackets to the underside of the counter. This would normally allow you the opportunity to simply pull the diswasher out a few inches from the counter for easy access. In my case, the lip of the counter did not allow me to pull the diswasher out very far, but I was able to angle it just enough to make access easier. Thirdly, I referred to the diagram that accompanied my replacement spring to make sure that I had the spring positioned properly. There appeared to be a slight difference between tension bracket spring angle for attaching the spring to the door vs side bracket. Fourth, I attached the vinly piece provided to the top spring connection and simply pulled down on the spring to create enough tension to attach the spring to the lower side bracket. Finally, test the door to make sure you have the proper resistance. Push the diswasher back into it's original position, realigning the top bracket holes and reattach the screws that secure the counter top attach brackets. Put away your tools, pack your patience and you are done. It's easy!

No spray-arm motion, no drainage (broken belt)
Getting the new belt installed is a bit tricky; it seems too small to span the pump and drive pulleys.

Nevertheless, start with the belt positioned in the drive pulley and stretch it so one side fits into the slot of the pump pulley. Using both hands, crank the pulley over until the belt "rolls" into place. It may take several tries as the workspace tends to be rather tight. Good luck.

Small / slow leak at bottom corner of dishwasher door.
After examining the door and main seal around the dishwasher I thought everything looked okay. I looked online to order a new seal anyway and discovered from others that the leak was probably the insulation strip inside the door rather than the seal around the dishwasher. I ordered an insulation strip and it arrived a couple days later. I removed the seven screws of the interior door cover and disconnected the electrical. After removing the old insulation strip and installig the new one I reconnected the electrical wiring/plugs, put the door cover back on, and reinstalled the screws. Total time was about 15-20 minutes and the leak stopped. It was very easy and saved the cost of a repairman or a new dishwasher. I'm very glad that I "listened" to others and went with the new insulation strip.
