Removed spray arm thumb nut. Removed spray arm. replaced worn and broken earings and re-assembled in reverse order. Would have done the repair a lot sooner if I had known that PartsSelect was just a few miles up the highway.

I first removed the wash arm retainer nut then lifted the arm assembly out and replaced the spray arm bearing ring and then set the spray arm back in place and put the wash arm bearing ring in the hole and screwed the wash arm retainer nut back in place. I couldn't believe how much the 2 had worn down. It is working fine. Saved me about a $125.00 service call out here as I live 50 miles from the nearest big town. Not bad for a 68 year old female!!

Dishwasher leaking at bottom of door

  • Customer: Eileen from Salt Lake City UT
  • Difficulty: A Bit Difficult

  • Tools Required: Screw drivers

Installed new door seal. Dishwasher still leaked. Googled the model number and then cleaned the filter at the bottom of the dishwasher, still leaked.
Verified that manifold bearing was not work. It was OK.
Found note that a plugged vent might cause leaking door. Very counterintuitive. Pried off air vent cover. Vent was thouroughly plugged with calcium deposts from steam. Cleaned these out.
Dishwasher no longer leaks.

Dishwasher Not Draining

  • Tools Required: Pliers, Screw drivers
  • 71 of 100 people found this instruction helpful
Ordered both drain & wash impeller kit and the drain check valve with o-ring. Decided to test the cheaper drain check valve first. Pulled dishwasher out from wall & adjacent cabinetry; removed drain hose from disposer and drained as much water as possible; "jacked" side of dishwasher to gain access to drain hose and drain check valve; used pliers to remove hose clamp; placed flat pan underneath to catch remaining water drainage; unscrewed drain check valve; tested under bathroom faucet--determined faulty; replaced with the new one, restored connections, reset dishwasher in proper location; voila--fixed! Plan to return the unneeded impeller kit.

Grinding Noise

Grinding Noise when running. I was not sure of problem and thought that a new Dishwasher may be needed if motor was the problem. After taking the bottom rack and spray arms out I came across my first problem. I believe it was the impeller design that has a 1in hex nut with a bolt in middle that needed to be removed. I needed a 90 degree 1in wrench to hold impleller while I removed Bolt. Luckly I have a friend that is a mechinist who made me a wrench.
After that the grinding cause was discovered - Broken glass that grinded the cermic shaft that is over motor shaft. I did not small drops of water under motor during grinding due to damaged cermic shaft.
$24 and 2 days later my dishwasher is as good as new. Sugguest you sell a 1in 90 degree hard plastic wrench for holding impeller which bolt is removed.
Thanks
PS. - Best part of your site is Parts detail which was very helpful for me to understand assembly.

Broken latch on dishwasher prevented operation

  • Customer: Thomas from Dunwoody GA
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers
  • 42 of 71 people found this instruction helpful
Photograph or diagram how the wires connect to the switches before taking out the old assembly. I could have salvaged switches from the old assembly by pulling out the white pins (and avoided buying the new switch kit). There's only one way the pieces go back together, so the wire connections are the only point that required special care and attention.

erratic lights, options unavailable, eventually no start

  • Customer: James from Boca Raton FL
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers
  • 25 of 27 people found this instruction helpful
removed 8 torx screws and inner door panel. took off electronics cover, unplugged connectors & replaced circuit board. ran ok for two cycles, then failed to start again. Sears svc tech advised circuit board and the touch panel housing would have to be replaced as a unit. parts and labor $319. $65 svc fee paid, rcvd $65 coupon on new machine. Went in again and blew out ribbon socket connecting touch panel and circuit board. Now running OK. (??!) $100 for circuit board is good deal. Wasted $65 on svc call, to find out cost of authorized repair service was 50% of cost of new machine. We'll see how long it runs.

Lower sprayarm nut stripped + broken inside Pump outlet

  • Customer: patricia from Chicago IL
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers, Wrench(Adjustable)
  • 28 of 37 people found this instruction helpful
You WILL need a star-tip screwdriver for this COMMON DU915 repair. We already had one.
The plastic "wing" nut which keeps the lower sprayarm attached to the pump assembly cracked inside where the threading on each part meets. Have been reattaching the nut to the Pump outlet for a year or so with super glue and finally found PartSelect.com. My husband had to fix this with a star screwdriver and vice grips (and he is super strong)-- otherwise an easy fix using just the manual supplied by the manufacturer. I just noticed the virtual repairman feature on partselect but we didn't need to go there.
The starhead screws that hold the pump outlet in place were on super tight. Other than that, no problem. It has been a week and the dishwasher works like new.
I ordered the parts online at 9pm at night and had the parts in my mailbox the next day - LESS than 24 hours later. How is that even possible?
Just ask anyone who knows me...I am NOT easy to please when it comes to customer service in any realm of the retail world - I have to say without any doubt PartSelect is the BEST experience I've had in my entire shopping life. It's as if customers run this company. I only wish they sold car parts, groceries, clothes and food.
I will be back to purchase again, I'm sure and I know it will go just as smoothly.
PartSelect.com...Please call me when you are ready to launch an IPO!!!!!!!

Worn out spring on detergent release box lid

  • Customer: HAROLD from FISHERSVILLE VA
  • Difficulty: Easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 26 of 31 people found this instruction helpful
First, examine very carefully how the old spring relates to the detergent release box lid. Note that the top of the spring has a square-end upside down "U" . This rests on a small ledge on the detergent box. Also note that on either end of the spring is a straight extension of the spring wire. These two "legs" must rest on the inside of the edge of the detergent box. Second, use a flat blade screw driver to pry the LID hinge pin from the mounting "posts. Remove the pin, first noting the position of the spring. Reassemble the spring on the hinge pin in reverse order. Then snap the lid onto the spring using the two mounting "posts". NOTE: I used a very fine needle nose pliers to move the two spring "legs" behind the detergent box edge after I had mounted the lid. Flip the lid down to test if the spring pressure on the lid can be felt. Harold Kitzmann, Fishersville VA

Door Gasket was bad causing a water leak

  • Customer: Edward from Springfield NJ
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required:
  • 23 of 23 people found this instruction helpful
This repair was very simple. I opened the door of the dishwasher then pulled the old rubber seal (gasket) out; I checked the old gasket to with the new one to ensure the new one was correct then installed the new one. There are two small rubber pieces located in mounting slots below the door gasket that slide out; I slide the old ones out and slide the new ones in. No tools required.
The thing that made the whole job easier was ordering the parts from Parts Select; I couldn't find exactly what I needed on the Whirlpool website but I found exactly what I needed on the Parts Select website and the parts were a perfect match.

Dishwasher wouln't drain

leaking water

  • Customer: mary from Fountain Green UT
  • Difficulty: A Bit Difficult
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 23 of 28 people found this instruction helpful
The first thing I did was to investigate. I needed to find where the leak was coming from. It was leaking from just above tne door front panel, directly underneath the control panel buttons. I opened the dishwasher door, and decided to remove the door screen vent. I was covered with some offwhite fiberous, or filter like material. I thought perhaps the filter had broken down, and I ordered a new screen. When it arrived, and, although I had expected to receive a new filter with the plastic door screen, I didn't. There wasn't one to be ordered. I looked at the screen again. My problem was, that although I had considered that the substance I had thought was a filter, was instead build up of detergent, and other particals. That idea didn't seem to make sense. I didn't think it was possible for that stuff to get to the door screen. I thought, it was too far away from the dispenser and food particles. As it turned out, the buildup was, in fact, the problem. I properly cleaned the door vent, which was then fine, and I put it back into the door. There were no more leaks, that was it, and the problem was solved. As a last note however, unfortunatley, I have to return the new door vent screen that I ordered. I enjoyed solving the problem, and you all helped alot. Let's do it again sometime.

Dishwasher finally would not complete cycle

  • Customer: Robert from Seattle WA
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers
  • 23 of 30 people found this instruction helpful
Symptoms: at first the dishwasher would wash the dishes but not stop at the end of the cycle. After several weeks of using a timer and opening the door during the drying cycle and getting an estimate of $421.78 to fix the machine (we declined) the dishwasher finally would not go thru its whole cycle. I reasoned it must be the Control Assembly and ordered one. to install it I removed the 8 "star" screws in the door, removed the inside of the door, removed the black, plastic cover over the Control Assembly, disconnected all of the connectors to the Control Assembly and the two anchor screws. The Control Assembly then was easily removed. The installation was done in the exact reverse of the tear down. After the door was reassembled the dishwasher has worked correctly for over a week. I saved about $320 by doing the job myself. I hope the machine operates for another ten years.
