WDT540HAMZ1 Whirlpool Dishwasher - Instructions

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.

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

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.

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!

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.

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!!!!!

Put the kick plate under the dishwasher and screwed it in. Easy!

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.

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 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

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

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.

Pull dishwasher out a few inches. Disconnect spring from plastic connector with long nose pliers. Remove connector. Replace friction sleeve. Replace connector.Reconnect spring to plastic connector. This completes repair.

The top and bottom parts of the lower wash arm were separating. This caused water to spray out the ends of the wash arm and come out the front of the dishwasher. In addition this water was not spraying upward resulting in dishes not getting cleaned. Took me a while to figure this out but the repair was simple.

1. Shut off water valve
2. disconnect water hose(wrench-adjustable)
3. Disconnect drain hose (screwdriver)
4. Pull dishwasher out from under counter
5. Put down towel to soak up residual water that drains out of dishwasher
6. lay dishwasher face down; electronics is located underneath dishwasher.
7. locate faulty drain pump
8. remove electrical connector from drain pump by first pressing on connector retention tab with screwdriver while sliding connector loose.
9. twist drain pump body while using screw driver to depress drain pump retention tab.
10. remove old drain pump body and insert and twist new drain pump body into old location (use screw driver to assist retention tab engagement)
11. attach electrical connector.
12. Return dishwasher to upright position, slide it under the counter (with its cotton cover); reconnect hoses AND turn water supply back on (make sure you remember to turn the water supply back on)
