That's it !!!!!!!!!!!!!!!!

I did not move the dishwasher out. It is a fairly tight space underneath, but the water inlet valve is located toward the front, so it wasn't too bad. The steps were:

1) unplug the power and turn off the water to the dishwasher.
2) remove the 2 wire connectors.
3) use the nutdriver to remove the 2 screws that hold the valve to the side of the dishwasher.
4) use a wrench (5/8") to remove the nut where the water goes into the valve. This takes some patience since you can't turn the wrench very far in the tight space.
5) remove the water outlet hose by using pliers to squeeze together the clamp and move it up the hose. Then twist the valve to free the hose and remove it from the valve. The nibs on the clamp are small and take a little time to get them squeezed together. If the hose has been on there a long time, you will have to twist the valve a few times to free it up.
6) now you will have to remove the sleeve that the nut was screwed onto. I had to take the valve to my vise to hold it. Then it wasn't too hard to remove.
7) use teflon tape before you reassemble. Just go in the reverse order.
8) hope there isn't a leak. Mine didn't.

The new water inlet valve seems to have fixed the problem!

Actual i missed diagnosed the leak and ordered a very expensive door gasket. The leak was coming from shrinage of the wax resevoire o rig and the tab seal for the soap dispensor. I missed the trees the forest got in the way. The leak was dripping alond the front panel well away from the main door seal.

I cleans a the plastic surfaces and noticed a lip around the opening for the reservoire and used 150 sandpaper to remove it. Replaced the O ring, tab seal and bothe selonoids and cleaned everything. Put it back together. Works find lasts along time

Peeled off the old foam strip, cleaned with rubbing alcohol, let dry completely, applied new foam strip,replaced door interior done I wish repairing relationships with fiance and kids were one tenth this easy.

First of all, rather then spending the 44 dollars on the main door seal simply cut yours in halve and trim a quarter of an inch from the disintegrated ends and use superglue and glue these ends together. this glued end will now be up top and in the middle and new clean ends will be down in the corners. next I removed the plastic door panel using a torxhead screwdriver, I just stuck the new inner foam pad on the old one. Then I glued rubber washers to the inner frame about 1/8 thick in the top 2 corners only. Finally I reattached the plastic door being careful not to tighten the torx head bolts just tight enough. It's dry and working good.

After realizing that both upper and lower sprayer arms had long thin cracks in them, I decided to try replacing the arms instead of the more expensive option of upgrading the dishwasher altogether. The top arm popped right out with no tools, new one popped right back in place. The lower arm is easily removed after unscrewing the large ring in the middle of the arm. New arm fit right in place and screwed the ring back on. Dishwasher working like new again!

threw out the broken and put in a fantastically improved new one. very easy (would have done it sooner if I'd known it was that simple to find it online and order it) thanks

slid the part in the groove (left side)

I replaced the door latch grommet just as everyone else has described on this site. It was pretty easy. I was amazed that such a little piece of rubber can let so much water get by. The inlet valve was not too bad either. Take the two bolts out that hold the bracket to the dishwasher. Remove the rubber hose on the back side and take loose the two electrical connections. My water line was long enough to pull it out in front of the dishwasher. Then I took the water line loose and removed the fitting. Installed the new one in reverse order of what I just described. These items took care of the bulk of the leaking problem. But I am in the process of ordering a new door seal which I hope resolves the rest of the issue. Also make sure you check the upper and lower control arms to make sure the spray holes are free of debris. This dishwasher was full of pieces of clear plastic that caused the spray arms to spray indirectly and towards the cracks of the doors.

Removed four screws on bottom plate. Located repair site on outside of cabinet. Had to hook spring on bottom rear plate by brail. Then attached linkage to spring and ran stiff wire through linkage to raise it above arm. Called a man with stronger but larger hands had him stretch the spring while I guided linkage over arm and into the slot using the wire. Removed stiff wire with needle nose pliers and reassembled front plate.

Took off the float, the jam nut was hard to get off, we ended up breaking the bottom piece of the float to get it off, but that was okay because we had a new float. The new float went on real easy and the jam nut went back on real easy. The foam insulation strip was real easy to get off we got a good hold of one end and striped it off slowly so there was nothing left on the door, then we cleaned the surface and put on the new insulation strip. We ran dishwasher to test it and there was no leak. Awesome. Cheap and easy to repair. We were impressed.

Sooooooooo, I ordered a new kick plate, it arrived promptly, tried installing it and it was being difficult. Removed plate above that and lined up new plate(kick plate) tried putting plate above it on and as when we installed the machine that upper plate was difficult. Removed upper plate to fcheck problem of installation and guess what? Stuck in the inside of the upper plate was the lower plate complete with sound insulation. Happy ending :-)

removed inner door panel. tested ythe Wax motor that operates the soap dispenser latch. It tested OK so I removed dispenser assembly. replaced the worn plastic parts and reinstalled the inner door panel.

Myscanning other reviews i saw mention dishwahser developed a small leak on RHS of door. I assumed the door gasket and planned to order that. On of the dispenser gromet which is only a $5 part so ordered that as well. I first replaced the door gasket which is an easy 10 mins job and ran the dishwasher again, but it still leaked.

I then removed the 7 torx screws on the door panel which came away easily. It was obvious that water was in there, so i removed the two screw on the dispenser with a nutdriver to replace the grommet. This process took 20-30 mins. After reassembly the leak was gone.

Without the comments on the website i would never have thought of the disepenser as source of the problem.

I have no prior experience fixing any appliance but figured I might be able to save this old dishwasher. I read some where on this web site that I needed to replace the upper and lower spray arm, and someone suggested replacing the filter as well. I ordered the parts by looking at partselect.com's picture of the dishwasher and read someone's explanation that I needed to remove the filter housing to replace the filter.

The upper spray arm comes off by gently pulling down on the spray arm. I put the new one in its place.

The lower spray arm had a thin, large (about 2" diameter) round screw holding it and its housing in place. I removed the large, flat screw and the lower arm came off. Below that was the filter housing. I unscrewed the six screws, took off the housing, replaced the filter, and put the housing back on.

Then I removed the lower arm from the plastic thing that was holding it, removed the stainless steel heat plates and put them on the new washer arm. Put the washer arm back on the thing that held it, and screwed the washer arm assembly in place with the large plastic screw.
