WDT730PAHV Whirlpool Dishwasher - Instructions

Something had been loaded in the dishwasher that had gone thru the basket - it hit the arm sprayer and broke it off.

Replacement sprayer was exactly the same - the partselect website has very specific identification method so you get the proper part. You must have your model number.

I watched a you tube video which was referred by part select. This was helpful.

I did not realize at first that only part of the arm sprayer had broken off. The arm sprayer broke off, but there is a base to the arm sprayer that was still attached to the dishwasher. So I could not, of course , fit the new arm with its base over the existing base because they are the same size. Once I realized this, it was a simple replacement, following the youtube instructions. You do have to press and turn counter clockwise to get the old base off, but once that was done, the new sprayer arm, which arrived attached to the base, easily fit, and press hard to turn it clockwise to reattach it..

It has worked perfectly. It is a hard turn to get the arm sprayer off or on, which is good so it doesn't come loose during washing, but when replacing it, you aren't sure of why it won't turn. It is a hard turn. Watch the you tube video.

thought it could be due to the overfill control switch,so ordered one and replaced one in the washer. However, it did not solve the problem. Having a repair company coming to look at the dishwasher. Tipped the washer on its back and switch was readily accessable. Only had to open plastic covering over the switch, disconnect the wires and install new switch and reconnect the wires.

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.

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.

Put in both a new element and thermostat. Did not fix problem. Using an ohm meter I did not measure any voltage to the thermostat. Suspect it’s a problem in the control unit, and decided to replace dishwasher.

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.

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!!!!!

At first I thought I needed a new bottom rack for my dishwasher. Out of curiosity, I watched the installation video and realized that the Tine Row installed separately and that was the only part I needed. I am appreciative of being able to access that video and the money I saved. Installation took seconds to complete.

Took off the old wheels and placed them on the new rack - fast and easy if you watch the video.

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

Very easy to twist off the old pump and replace with new part. Worked perfect after replacement! We just followed you tube instructions

Top of stop slides on and push bottom in ,will click

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

Removed broken tin row. Replaced with new tine row. Tokk less than 1 minute.

Replaced the strainer. This keeps the two sprayers clean/clear so they do not clog up. Dishes are cleaner now. Note : if your sprayers are clogged it is a long process to clear out the sprayers. Dishes will not be clean until your sprayers are all cleared.
