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

Who ever assembled the parts for shipment, put the latch on backwards and it was extremely hard to take the latch off of the main part. Now matter how hard I tried, I was unable to re-attach the latch until I used a file on the plastic insert to file off the inside edges until they fit. It does work now, but it could have been made much easier if they had simply positioned the latch in the correct position in the first place.

Remove all interior door panel screws with a torx head screwdriver (drill). Pull the interior panel up from the door far enough to access the switch assembly. Pull it out and remove the 2 electrical connectors from the old switch (using a small screw driver as a pry bar if needed). Remove the old switch and handle (that may be broken off and still in the door). Push the electrical connectors onto the new switch assembly, making sure the handle is down toward the opening and the connectors are on the same side as they came off of the old switch. Align the mounting screw holes of the switch with the threaded holes on either side of the switch. Push the interior panel back together and align the two holes with the switch holes (those 2 screws go through the door panel and the switch assembly). Replace the remaining interior panel screws. Done!

Replaced the door gasket, inner foam strip and the bottom seals on the door. Unfortunately I broke the plastic door latch handle in the process and had to purchase a complete latch assembly too.

A common theme you'll see thoughout the repair stories;

1. many broken handles at the hinge
2. TURN THE POWER OFF.

This assembly comes with the microswitches (which is not a bad idea to replace since they are electromechanical and will eventually fail). My only recommendation is to buy a couple of these handle assemblies because they WILL fail. I'm on my 3rd!

Door gasket fit in like a champ! No special tools required - just scissors to trim off the excess ends. Unfortunately this didn't correct the leak. The leak was caused by a Home Inspector who ran the dishwasher without soap. The soap has a defoamer in it. If you run the dishwasher without soap the water mixes with the surfactant in the jet dry and causes foam which results in a door leak. The foam also causes the pump to cavitate which is not healthy for the pump.

Basically took out of box and put in dishwasher.

Received the entire latch/switch assembly rather than just the plastic latch handle. This was a pleasant surprise, especially for the price. The latch assembly was clearly a better designed and more robust assembly than the original.
Removed the inside panel of the door by removing the dozen or so TORX screws.
Pulled the inside panel away from the outside door panel (gently, cables attached) to gain access to the latch/switch assembly. A second set of hands was helpful for this and some following steps.
At that point the latch assembly was free mechanically from the door, but there were two wiring harnesses attached to the latch assembly via plug connectors to the two microswitches on the latch assembly. It looked like it was going to be easy to unplug the harness from the switches, but I could not do it. Never did figure out how to do it.
Removed the two microswitches (with harnesses attached) from the 'old' latch assembly by pulling back the plastic tab that holds each switch in place. At that point the rest of the latch assembly was completely free from the machine.
Removed the two microswitches from the 'new' latch assembly using the same method as above. This step requires care as the plastic parts and switches can be damaged.
Put in place the two 'old' microswitches with wiring harnesses attached on each side of the 'new' latch assembly. These snap in place. This requires care, as above, and the second set of hands to hold away the inside door panel.
Put the latch/switch assembly in place in the door, and put the inside door panel back in place.
Re-installed the TORX screws holding the inside door panel - and latch assembly - to the door.
I kept the 'new' microswitches because one day the 'old' switches may fail. If that happens and I want to replace the microswitches, I still don't know how I will remove the switches from the wiring harness. I guess I'll figure that out if the time comes.
Except for the difficulties disconnecting the microswitches from the harnesses, this was an easy and straightforward job. The latching of the door seems more positive, now, and the machine is working fine.

I followed the directions in the dishwasher manual how to remove the top rack of the dishwasher, basically removing the stops on each side, and I set the rack on the counter. I replaced both sides even though one had not yet broken. To replace the part, 5 screws had to be removed; I used an allen wrench. The replacement location of the part was pretty obvious once the screws were removed. The inside of the plastic piece that was opened in the process of removing the defective part was dirty so I took some time to clean that out before attaching the new part. The actual unscrewing and attaching the new part probably took 10 or 15 minutes per side. It took a few tries to get the height adjusting lever to move freely before I tightened the screws. The rack works great now.

Took the dishwaher apart. Found out the float was damaged. Replaced the float and the float switch. Put back together

remove old seal, put in new - my 10 yr old could do it. Note - there is a white mark on the back of the seal indicating the middle so you can line it up when installing the new seal - makes it easier.

Snapped out the old retainer, snapped in the new. Then snapped in the washer arm. Done. Works great.

Removed the bottom tray. Removed the two clips in the top tray guides and removed the top tray. Removed the top spray arm and transfer tube by unclipping it from the top and at the back and then rotated it down and out. Removed the six screws around the upper pump housing and removed it along with the bottom spray arm. Removed the three screws holding the filter protector plate and removed it. Removed the two screws holding the accumulator / flow plate and removed it. Put it back together in reverse order careful to not over tighten the screws.
