WDT720PADM1 Whirlpool Dishwasher - Instructions

Snap in the missing track stop and twist snap the middle spray arm. That simple.

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 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.

Exact fit and at my door in two days

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.

simply line up the new pin with the rectangular slot in the kick panel and metal panel behind, slide the pin in and turn it with a flat blade screw driver.
NOTE: the original pin was black. A black replacement part cost $29 plus shipping! A knock-off pin was only $6 plus shipping. I got the cheap one and colored it with a black Sharpee marker before installation.

Thanks to everyone for posting their experiences on changing the heater element. The most difficult part of the repair was getting the dishwasher out of the cabinet. I didn't know that I should disconnect the water line underneath the sink and this would make the removal easier. Also, because the copper water line going to the dishwasher was kinked, I ended up changing it with a flexible steel braided line.....much easier to install.

Once the dishwasher was out of the cabinet, I turned it over and easily removed the clips that held the heater element in.

I would definetly recommend people doing this repair themselves, it will save you a lot of money!!!!!

Initial inspection of the issue and research suggested the door latch was malfunctioning / broken. I bought the part and expressed it home. The installation involved removing the door screws on the inside of the door, separating the front and back panels, unplugging the door latch, removing it from its niche and popping in the new one. Reverse the take apart and it was done. Very simple swap. Hardest part was juggling the two halves of the door and preventing the door for trying to close in the process as the bulk of the weight is in the outside half of the door.

The new part did not fix the issue. The door strike was the next part that could be broken / malfunctioning. I ordered that part as well and replaced it. In the process of replacing it I found that the original door strike had been installed upside down. I am guessing it was installed at just the right pitch, or maybe even bent at the manufacturing facility, so that it latched. No idea how it managed two years like that. I installed the new one correctly and the door latches perfectly. Both parts I removed from the unit I will retain if my new parts should fail in the future.

I took the valve off and actually hooked 110 volts to the vale and tried to blow through it and it would not let air pass through it. I replaced the the new valve in about 15 minutes and it works fine

Popping out the old tine rows was very simple and required no tools. The only issue was that the spacing of the replacement tines was different from the original parts and there was not enough space between the tines and the basket to snap the clips back on to hold the tine row. I went to my band saw and cut the extended ends off of the clips and then they snapped into place perfectly. This would have been a 20 minute, no tool job if I didn't have to run to the band saw.

The old filter simply unscrews and the new one screws in.

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.

The air just unscrews with one twist and the new arm twist right back on. No tools needs. Saved me $100 service call.

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

Screwed the cap on to the rinse aid receptacle.
