WDT730HAMZ1 Whirlpool Dishwasher - Instructions

My wife hired a local repairman when the right side spring cable broke (I was out of town). He took two hours to fix it (and two appointments). The door would then pop open when running. He came back and replaced the latch. Problems persisted. I then ordered new hinges and replaced both in half hour or so. Would recommend doing all of these repairs yourself. None of these repairs are that hard and definitely not worth paying hundreds to do it. Trickiest part is pulling the dishwasher out from the counter without impacting the electrical or water connections. Disconnecting the power is important on all repairs. When you take the screws out of the door to get to the hinges, make sure you have a helper just to hold the door up while removing the last few screws. The left side hinge was really bent (when the right side spring cable broke) - caused the door to be out of square and thus would not effectively close. This was obvious after a 5 minute search on this this and other repair sites. Process that I used: 1. remove screws from both sides holding dishwasher into counter (may have screws into countertop as well). 2. turn off power, 3. pull out dishwasher far enough to see hinges and springs (careful of connections), 4. remove front door screws, 5. take off front panel, 6. remove spring cables (pull cable taut and remove "hook" from hinge)., 7. unscrew two screws holding hinge to door, 8. bend metal fingers around hinge pin to be able to remove hinge., 9. attach hinge in opposite path. 10. repeat on other side (if necessary), 11. reconnect things in opposite order...test door prior to reattaching door panel. Make sure you level the unit with the adjustable feet. Make sure screws in sides of cabinet aren't too tight as it can take the unit out of square pretty easily...

Did the repair, but needed one extra step not described in video:

I followed the directions on the PartSelect Youtube video - very helpful! I do believe the heating element was the original culprit, as it had a "burn" area about the size of a dime that caused it to almost break into two parts. Obviously a point of failure.

BUT - after replacement, it still did not solve the problem of the dishes not drying.

After much web searching, I tried the diagnostic mode on the dishwasher, and that did a hard reset of the logic board and FIXED the problem.

So in all, it required both a new heating element AND a hard reset via diagnostic mode.

Turned off power to the dishwasher. Removed the front panel via the screws on the inner wall of the door. Lifted and pulled out the front panel. Disconnected cable connections to fully remove the front panel. Pressed down on the latches to the left and right side of the door latch. Pulled out the door latch. Put in new door latch until it clicked into place. Reattached cable connections. Put the front panel back on with the screws. Turned back on power to the dishwasher.

I simply had to hook up the power cord to the dishwasher so i could plug it into the outlet rather than direct wire the appliance. Everything went very smoothly. Everything needed for installation other than tools was provided. Easy to follow instructions if you know a little about electrical wiring.

Also replaced stop ends for top rack by removing old clip in to push down and lined up to secure in slots at end of rack, notice new plastic parts are installed by pushing hardware into slots downward until they clip into place

Disconnected the damaged hose extension from the dishwasher outlet drain hose and the connection to the sink drain. Removed two clamps. One a spring clamp and the other a screw clamps. Connected the new extension hose with a spring clamp to the dishwasher outlet drain hose. Connected the other end to the sink drain with a screw clamp. Checked for leaks. Good to go!

Only one friction sleeve was broken. So I pulled out the dishwasher to see how the one on the other side went on. It was very easy to replace and I replaced both. Unit works fine now.

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.

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.

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

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

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