WDT780SAEM2 Whirlpool Dishwasher - Instructions

Gently pull the old door seal out of it's track observing the orientation of the seal and the amount of extra seal at the ends of the seal grove/track..
Start installing the seal on one side leaving about the same amount of extra seal as original seal before removal.
Be sure the seals orientation is the same as the seal that was removed.
Carefully pressing the seal into the grove/track designed to hold the seal. Be careful to fully seat the seal into the grove/track.
The corners will be a little tricky, but carefully press and seat the new door seal all the way around. There should be a little extra seal after you get to the end of the grove/track.
Good luck, the new door seal solved my water leak.

After replacing the door seal and the dishwasher still leaked a lot of water out the bottom of the door, I read posts by a couple of other DIY who said the lower spray arm can split at the seam and cause this. One post noted it is very difficult to determine if this is the problem, that you may have to take the blade of a screwdriver and try to pry the seam apart gently to see if a gap does appear with very little force being applied. If so, then just imagine what happens when that very hot water makes that plastic more flexible and then the seam opens and forces waves of water against the lower door. I could see a small seam split using that strategy and when I replaced the spray arm, my leak stopped. I don't regret replacing the door seal as it had a couple of small tears and hard water deposits all over it, so it was time to do that even though it was not the culprit for the extensive leak. The arm is SO EASY to replace, just twist the plastic nut under it and it pops right off. Put the new one on and twist the nut the other way and it secures it.

I opened the package took out the replacement part and installed it with no tools. Easy, done in 10 minutes.

First, I bought the door balance link to replace the broken links that connect to the springs.

Because I didn't have enough slack to simply pull out the dishwasher far enough to reach the springs, I had to disconnect the water line and electrical wiring.
The only reason my repair took as long as it did was because there was so little room underneath the dishwasher for disconnecting the water line. I had to buy a shorter adjustable wrench. Also, I had leaks after reconnecting the water line. I had to tighten the compression nut as far as it would go. The nut wrapped around a white substance that had been applied to the threads (I believe this is called pipe tape), which did the trick for sealing the leak.

The repair was a complete success! The parts arrived fast and the information from other customers on the the PartsSelect website was invaluable.

The rubber door seal was easy after watching the video. I key point however is that you do have to stretch the seal just a little bit. The video says not to. If you don't like I didn't originally, the seal will only extend from one side to the other without about an inch excess that folds on the bottom of each side. The door still leaked a little without the excess folded on each side. I did one side at a time and pulled out the new seal along the side before curving to the top, and just stretch it slightly to allow the excess. This stopped the leak.

The lower door seal was ok to do. The most important step there is to remember how the front door panel is installed. Taking pictures before and during removal may help. It is awkward to do by yourself, but can be done. I found that putting a balled-up towel at the top of the door helps when trying to reinstall the front panel.

Pull the old seal out and push the new seal in. Done. Easy. The only issue is the door is still leaking and I have to replace the seal and the plate that goes across the bottom of the door.

Order both this seal and the seal for the bottom of the door at the same time.

Follow the u tube instruction. Replacing the pump was very simple and easy. The hard part was getting the dishwasher out of the cabinet and back in again.

The repair was similar to the very good video provided by PartSelect. However, I did make a few changes. The new rack was slightly different in the front side compared to the old rusted rack. After I removed the old rack from the dishwasher, I placed the two racks side-by -side to make sure they were compatible. They were identical in the rear structure and overall size, so I proceeded to change out the wheel racks, rack height adjusters and upper wash arm to the new rack. I suggest transferring each part one at a time so you can get the spacing correct. Also, in my case, many of the items needed to be washed with water to remove soap buildup in these parts before moving to the new rack. I would also suggest putting the upper wash arm (needed in this case) on the new rack last. The total job took me about an hour including washing or rinsing all parts and reassembly. This is an easy job, just take your time and do one item at a time so nothing gets mixed up. I used a drill driver to remove a total of 4 Phillip head screws for the rack height adjusters but a regular Phillip head screw driver would work as well.

Removed the inner panel, remove electrical connection to dispenser, remove dispenser, metal tabs that hold it in, are a bit hard to pry metal tabs, and when installing net dispenser tabs are also a little difficult to pry tabs to install but doable. So far works like it should.

I read how other people had the same problem, I checked everything that could possibly cause this. I then believed I knew what was wrong. I ordered a new arm. It was unbelievable how easy it was to replace.it. It took less time than a minute. . Turn the nut holding the arm counter clockwise to remove the arm. To replace turn the nut clockwise I now have a working dishwasher. It is not necessary to remove the dish rack.

We took the rollers off the old one (new ones came with the dishrack also) and put them on the dishrack (they snapped on). There was also an extra piece that we figured out how to put on. Then slid it in place and it was fine.

pushed the new retainers in the holes and we are set to go

My husband did the repair. It was very easy. He basically just popped off the old wheels and popped on the new ones.

slipped new one into slots

I had a common issue on many dishwashers, the final drain cycle was not draining but the pump was trying to turn. Also, the drain pipe was clean. This issue caused a burning smell, like a circuit board heating up. Half plastic smell, half electrical. I bought a replacement pump, followed the pump replacement video instructions from PartsSelect, and it was replaced in under 15 minutes without any tools.
