Machine began making noise as if something had let go and was beating on the machine

I removed the plastic retainer that held the lower spray arm in place. After removing the lower spray arm I was able to remove the 6 hex screws that held the cover over the filter screen and the discharge housing assembly. I was then able to remove the bolts that held the upper part of the discharge housing assembly, and replaced it with the new part that I received. The rest of the job was simply putting it back together.

Note: While repairing the broken part, I noticed a small leak under the machine around the float assembly. This was simple to fix. Remove the small lock ring on the bottom of the float. Pull the float out and clean the grease and soap scum out of it. Put it back in and attach the lock ring. No more leak and the water gets turned off when the float activates the switch. Something that everyone should check periodically.

loose top basket/

I had two problems with the dishwasher. The top basket was loose, but the main problem was a plastic part inside the bottom assembly.

The part was backordered, so I re-ordered it through Sears. They said it would arrive in two days. Theirs came in two weeks, and their customer service was terrible.

Your "backordered" part came in two days, even before it was supposed to come had the part not been back ordered. I am delighted with your customer service and your company.

The illustrations on your website were excellent. They helped us not only to identify the part, but to diagnose the problem.

This was my first purchase through your company and if I ever need parts again, there is absolutely no reason to go anywhere else.

You have an excellent company, and great website! I bookmarked your page for future purchases.

Failing to complete any of the cycles properly, repeated "click" heard from control unit.

It was initially unclear precisely which part I needed. I called PartSelect customer service and the agent was extremely helpful and able to quickly advise me on the correct part.

Installation was straight forwared. I used a torx screw-driver to remove the screws holding the inside-door planel. There are wires attached so this needs to be done with care.

I then removed a thin plastic film cover the control assembly. The control assembly is held firm by a screw and is also "snapped" in place. There are obvious tabs which can be spread to allow the assembly to be lifted out.

Each of the wire harness can then be removed from the control assembly.

With the new control assembly in place, the wires can be reconnected very easily. The assembly board itself is well marked enough to determine where each of the wires connects but really, the connectors for each harness is unique so pretty difficult to not get right.

Replace the plastic film and door cover and you are back in business.

I had previously gotten a quote from Sears to do this work and it was over $200 works of labor. Go through PartSelect I not only saved about $40 dollars on the part itself, I also saved $200 on a fairly easy repair that I could do myself in under 30 minutes.

Rusted upper and lower racks, broken tines

Read the experiences here, very helpful. Bottom slides out first - really easy. The new part comes with rollers, you don't need to remove the old ones. Now the only problem, getting the sprayer off the bottom basket. Look carefullty, you must use a screwdriver to release one side of the sprayer, then it works off easily. Make sure you note the orientation of the base of the sprayer. Reverse steps above and you are done. New tray slides in. Our new tray was a bit wider than the old one so we needed to use a bit of pressure to "shrink" the back just a wee bit.

The upper is easy also. Since the rails are uneven, make sure you put the high rollers on the high side no matter what your wife told about how it is supposed to go in. The end caps snap inward and slide out of the rails. Easy once you know. The uneven rails are obvious once you notice. Total time was 45 minuts, 30 of which was figuring out how to get the sprayer off without damage.

Would be nice to know the factory recommendation for removing the sprayer.

No water in the washer barrel

Diagnosed potential problem from scematic diagram found at Parts Select .Com by entering model #. It was very likely the inlet water solenoid. Tear down was simple: Turn off water, disconnect water lines to and from solenoid, disconnect two electric terminals and remove part by removing two screws from dishwasher chasis. Before you buy the new solenoid, unscrew the water inlet elbow from solenoid and check the filter/screen inside the solenoid to make sure it isn't clogged. Assuming it's not, order the replacement part and reinstall in reverse order. Be sure to use plumber's tape on screw connections to make sure there are no leaks..... Also for ease of acces, you'll need to turn the dishwaher down on it's front. Put towels down to cushion the front and keep the controls from contact with the floor. Good luck!!

I took the bottom cover off and pulled off 2 wires and removed 2 plastic nuts. I removed the old part and removed the O rings from the old part and installed the new heating element. Replaced the plastic nuts and the two wires. It was very simple. The hardest part was lying on my back to get to the wires and nuts.

Upper washer arm holes plugged up

The upper washer arm can be removed by just snapping it out of place. Just take a screw driver and put in underneath the spray arm and pry it out of its socket. It will just snap out its place. Sometimes this retainer will break so make sure you have this retainer before trying to remove the upper spary arm. I removed the spray arm and back flushed it out with a garden hose to get the debri out of the washer arm. The holes are all clean now. Washes much better now. To put in back on just put the washer arm back where it goes and then just snap the clip back in its hole. Pretty easy fix.

Racks were rusting, pieces braking off and rubber coating was peeling.

Was extremely easy to remove that existing rackings(upper and lower), install the new racks and snap in the new spray tower. It now looks like we have a new dishwasher. We are hoping that it will last another 10+ years.
We will recommend your site to friends.

Squeezing the handle did not open the latch

  • Customer: Robert from Ocala FL
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Nutdriver
  • 8 of 8 people found this instruction helpful
After unplugging the dishwasher, I opened the door which required more pulling effort than it should. There were 10 screws which fasten the inside panel to the door. 2 of these are located next to the latch. I used my drill driver with a star bit. By carefully separating the panel from the door, I was able to see the inside of the latch mechanism. The plastic handle had 2 ears that had snapped off. It was fairly easy to remove the broken handle and replace it with the new one. All that was necessary then was to replace the 10 screws and tighten them. It seems to be fine now.

After repairing this dishwasher 5 times during the past 8 years this one was real easy: Open door, unscrew inside cover and carefully move over to one side. Unplug soap dispenser, unscrew soap dispenser and remove. Fit new dispenser, reconnect it, put inner cover back in its place and secure it with the retained screws and you are back in operation. Hans.

Most difficult was figuring out how to release the top rack...just flip the end pieces to the side and out they come. Next was removing and reinserting the spray head in the bottom rack...just twist and take out then align and twist into place in the new rack.

Dishwasher door was crashing open

The replacement of the spring linkage was simple - the pulling out and pushing in of the under-the-counter dishwasher was the difficult and time-consuming part. The repair of the part took less than a minute.

The actual repair -
1. Hook the linkage to the dishwasher door
2. Hook the spring to the dishwasher base
3. Hook the spring to the linkage.

Getting the dishwasher out to be able to make the repair involved:
1. Unscrewing the base panel (6 screws had to be removed)
2. Unscrewing the dishwasher from the counter (two screws)
3. Turning off the water supply
4. Disconnecting the inline water supply from the dishwasher.

Once the part was replaced, I had to return the dishwasher to its original position, which meant performing the four steps (in reverse) used to pull out the dishwasher.

Upper carriage wheels broke.

The only tricky part was fixed by reading another post on this website -- removing the plastic endcaps on the steel sliding brackets. This is a necessary step before replacing the wheels because the bracket needs to slide between two fully installed wheels.

To remove the endcaps, you must push the flat end of the endcap (the side of the endcap facing you) sideways toward from the dish carriage, with your thumb. Once that slides sideways, the entire endcap can be easily pulled from the bracket. Not much force is required for either step in removing the endcap. If you look closely at the endcap, there is an arrow to show the direction in which to slide the flat portion.

The wheel can be bumped onto the wheel axle by placing a wooden block against the outside of the wheel and then applying a gentle tap of a hammer to the block. Use a flashlight to make sure the wheel hub rests against the washer tub sidewall.
