Dishwasher wasn't cleaning well, especially top rack

  • Customer: Casey from Wadsworth, OH
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers

I wanted to get the dishwasher cleaning better and thought that maybe the accumulator needed to be replaced. I figured that I'd swap out all the spray arms as well, just for good measure.

I needed Torx screwdrivers (T15 and T20, I think - not 100% sure on that) and patience because there's really quite a lot of screws to get the accumulator out. Finally got to it and it didn't look damaged, but replaced it anyway.

The spray arms are easy - they just snap in except for the lowest one, that had a plastic nut. I ordered a replacement nut just in case I broke this one (you know how that goes) taking it off. Well, it took pliers, but it came off ok.

In the end, my dishwasher is happy and cleans much better now.

First replaced rubber seal around door, which did not stop the leaking.
Then ordered insulation foam strip and replaced old one, which fixed problem. Put new strip over the old one because tub was slightly warped.
Very pleased with order speed and cost.

The adapter still needs another union to fit to the faucet . I have tried Ace Hardware, Lowes, Menards, Danco, Price Pfister and many online plumbing supply and hardware stores and am not able to find a union or combination of unions to fit.
I need an adapter with two 55/64-27 male ends.

Used torx bit to remove screws on door and removed the back of door. Removed wiring from switches (2) on broken latch and removed latch. Plugged in switches on new latch and placed latch in position. Screwed back of door into place and that was it! Very simple task and new latch looks and feels much more sturdy than old one.

Door Latch Failed

  • 9 of 10 people found this instruction helpful
Turn-off the dishwasher power at the circuit breaker. Open the dishwasher door flat. Remove the 11 screws around the perimeter of the door using a t-20 torx bit (available at any hardware store). The latch assembly is held on by the top middle two door screws. Pull latch assembly out from top of door. Remove the black and white cable assembly connectors from the latch assembly making sure to note which side each color is on. If you have trouble sliding the connector off, use a flat screwdriver carefully to pry it, but do not pull on the wires. Install cable connectors onto new latch assembly making making sure the black and white cables are on the correct sides. Position the door at a 45 degree angle and place the latch assembly into position while putting the white inner door over it. Reinstall the 11 torx screws around the side of the door being sure the screws are snug, but not overtightened. Test the operation of your dishwasher. The new latch assembly seems to be built better than the factory original.

The door would just flop down when you opened it

  • Customer: David from Plano, TX
  • Difficulty: Easy
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers

The spring mechanism is on the side, so you have to pull the dishwasher out onto the floor. To do that, you have to remove the floor molding (preferably without breaking it) and remove the base coverings (painted metal plates on the bottom of the washer. Unscrew the side gasket plates on the side of the dishwasher (just inside of the door) where it attaches to the cabinet and the screws in the braces at the top (inside the door) where it attaches to the counter top. Now you will be able to slide the washer forward to look at the sides where the door springs are. Depending on the floor, you may have to raise the washer's front feet. They screw up. As you pull the washer forward be careful to not mess up the insulation which drapes over the top and sides. You only need to come out 1/3 of the way to see the sides where there is a plastic wheel at the forward bottom corner. As you move the door up and down you can see the hook where the cable goes and further up the side you can see several notches where the spring goes. Hook the cable and bring it around the wheel and attach it to the spring. To reinstall, just follow these directions backwards. Good luck.

Lost the faucet adapter

I had to replace the faucet in the kitchen sink orignnally. However since I use a porteable dishwasher, its hose connects to the kitchen faucet. The new faucets aerator is threaded differently than the old so that the dishwasher adapter would not screw in. I had misplaced the adappter kit that came with the dishwasher last year, so I ordered the adapter from partselect.com. when the part came a few day it was a simple as screw out the old aerator, screwing in the new adapted and then putting the modified aerator from the old faucet back in so that the dishwasher can be connected as needed.

Upper Rack not Cleaning

  • Customer: Stephen J from Sammamish, WA
  • Difficulty: Easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 8 of 8 people found this instruction helpful
First I read all the reports for not cleaning properly already listed on this site. I had to replace the docking station with flappers. When I removed the station I lost the flappers down the water delivery tube just like Jon said I would in his repair post so I removed the water distribution assembly fished out the old flappers and snapped in the new.
But then I figured I might as well check out the accumulator while I was in the tub anyway - I had read that you need Torx screwdriver bit, which I had, undid the screws, pulled out the accumulator screen which was about 80% clogged, discovered I need a new chopper blade and my impeller is disintegrating, put it back together and lost ten minutes looking for the three screws I had incorrectly put in too soon, and now it is cleaning a packed full load like it was supposed to do.
**I love this site - I went to the virtual repairman and it listed every problem I had with this appliance in the order they happened (door latch broke years ago). - I think I am going to look up stuff that I own so I will know ahead what could go wrong with them.

And absolutely NO DUCT TAPE was used in this repair.

Small / slow leak at bottom corner of dishwasher door.

  • Customer: Adam from Acworth, GA
  • Difficulty: Really Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 9 of 11 people found this instruction helpful
After examining the door and main seal around the dishwasher I thought everything looked okay. I looked online to order a new seal anyway and discovered from others that the leak was probably the insulation strip inside the door rather than the seal around the dishwasher. I ordered an insulation strip and it arrived a couple days later. I removed the seven screws of the interior door cover and disconnected the electrical. After removing the old insulation strip and installig the new one I reconnected the electrical wiring/plugs, put the door cover back on, and reinstalled the screws. Total time was about 15-20 minutes and the leak stopped. It was very easy and saved the cost of a repairman or a new dishwasher. I'm very glad that I "listened" to others and went with the new insulation strip.

Drain pump noisy

  • Customer: Scott from High Point, NC
  • Difficulty: Really Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 9 of 11 people found this instruction helpful
As others have described once you slide the dishwasher out and tilt it for access you simply remove the discharge (use something to catch the water), torx screw that secures the bracket to the unit, and twist counter clockwise until the pump is free from the drain tub. Reassemble in reverse order

Detached Water Distribution Manifold

  • Customer: Harry from Bensalem, PA
  • Difficulty: Really Easy
  • Time to Complete: Less than 15 mins
  • Tools Required:
  • 11 of 18 people found this instruction helpful
The original brackets that hold the water distribution manifold to the back and top of the tub came off the "X-shaped" plastic posts on the tub walls. That caused the upper wash arm to sag down into the travel of the upper dish rack and was broken off when the rack was pushed in.
I bought 2 new brackets and a new wash arm. The new brackets had a smaller aperature than the originals and fit tightly onto the plastic posts, holding the manifold firmly in its proper location. Replacement of the brackets and the new wash arm took less than ten minutes and required no tools!

Removed the basketsThen removed the bottom spray arm with nut driver. Removed the cover and spray tower assembly. removed screw holding broken impeller. Replaced and reversed process. Really easy. As an aside. This dishwasher has been a major disappointment. lots of things not holding up. Didn't go cheap when buying it. Nice to find a site with good prices for parts
