I was hesitant at buying the Matag made replacement, especially since it was one piece as compared to my 10-year old 3 piece assembly, and my dishwasher is KitchenAid.
Ordered on a Sunday afternoon, had in hand Tuesday same week, one phillips head screwdriver to remove/replace. Everyone smiling!
Did not need to remove upper rack. Simply unscrewed 1 screw, put on new one-piece arm, replaced with same screw.
15 minutes!
Good price/delivery.

The plastic disc which sprays the jet has snapped off. This is the disk with swirl pattern on the back face.

1) Removed the two white clips from the left and righ hand side of the top tray roller rail. this allows the tray to be completely removed and ease access to the washer assembly. The clipe looks like the letter "k", so you will need to close the "k" to almost straight line in order to get it through the hole.

2) Put a sheet or a towel at the bottom of the machine, just incase you drop the two small cross head screws. This prevents the screws from falling to the bottom of the machine.

3) Remove the screws. At this time the washer assembly will/should slip out very easily. very little force is required to pull the assmbely out.

4) Slip on the new washer assembly and put the screws back in place. Tighten screws, Be careful not over tighten the screw as you may crack the plastic flange.

Note: My machine is an older model, so the washer assembly had two screw fixing. The new assembly only had one hole. Although one fixing appeared to be sufficient, I decided to drill a hole on the other side and this worked fine.

5) Replace the top tray, taking some care to ensure rollers are correctly located within the rails. Then replace the clips and job's complete.

The old gasket came out easily, but had calcium deposits in area. I cleaned the area with vinegar and water and waited until it was completely dry. The new gasket went in very easily and looked great. I started the dishwasher and alas, it still leaks, so the problem was apparently not with the gasket, but some other area. But the gasket is nice and new. Any suggestions on next step0 in troubleshooting?

Water leak from center of motor unit

Removed dishwasher, take to garage, removed lower rack to gain access to top of motor unit. Used star socket wrench to remove upper screws holding top of unit in. Disconnect wires, drain tube and counter weight. pulled motor unit out from inside dishwasher and placed on bench. Proceeded to disassemble motor. Some things were obvious, others not so. replaced old worn out parts with new, used a little lube (Vaseline) in places to assist in getting seals back in place. Instructions were of little help need to pay close attention when tearing unit apart. Reassembled with new seals, installed motor and re-installed dishwasher...NO LEAKS!! Wife and I happy.

Upper Spray Arm didn't work

  • Customer: Steve from Lindenhurst IL
  • Difficulty: A Bit Difficult
  • Time to Complete: More than 2 hours
  • Tools Required: Screw drivers, Socket set, Wrench set
  • 4 of 5 people found this instruction helpful
replaced spray arm, but this did not resolve the problem. The troubleshooting guid (inside kick panel) indicated the check valve may be stuck. We had quite a bit of lime build up, so I suspected the loose deposits may be stuck. I removed all of the deposits, disassembled the lower unit.
Removed lower spray arm, removed spry tube. The tube is two pieces. first the upper portion must be removed (two screws-place towel on base of tub to preven screws from falling into the chopper area), and then the lower portion simply rotates clockwise 1/8 of a turn. The attachment for lower spray arm has a small plastic bearing, careful not to drop it.
The dishwaser then had to be pulled out and turned on the side. I removed the entire lower unit by removing the white tabs (3). Careful, because the unit is now free to drop into the tub. Next I removed the pump. This is tricky as you have to remove the aluminimum bracket to get to the mountin bolt. The bolt turns out easily w/socket and extension. The pump motor is then rotated counter clockwise, and pulled from the pump. Takes a little force as the gasket makes for a tight fit.
I then removed the choper / pump unit from the basin. The build up behind the chopper screen was extensive, so I had to remove the screen and then the chopper cover. After cleaning, the check valve was unplugged and I reassembled the unit.

Dishwasher works great now.

This is the second time I have replaced a rack. You just pop on the new rollers and you're good to go!

The top drawer wash rotor hose was leaking badly and as a result allowed uneven water flow to the upper drawer of the dishwasher.

I first had to take the upper drawer of the dishwasher out so that I could get to the faulty part. This was a little tricky as there were two clips that had to be removed from the arm slides before the upper drawer could be removed.
I then realized that the faulty part DID NOT exactly match the repair part I received. The original connection wand was in two pieces where the repair part was all one piece. That required a bit of thought before I began the repair. There was NO drawing accompanying the new part, so I had to decide how the part would be connected. After a little trial and error, I determined the arrangement of the repair part and completed the repair. All in all, it went well, but there was a few anxious moments when I first saw the difference between the original part and the new part.

soap door on dishwasher broken

  • Customer: george from ten mile TN
  • Difficulty: Very Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers
  • 4 of 6 people found this instruction helpful
Got the new door and tried to put it on. The door went on very easily. However, there's a spring that opens the door when the main wash cycle comes around. I never did get that spring right. None of the drawings showed the correct position and after an hour of trying to get it to work right, I gave up. The door comes open slightly (but not because of the spring) when it's time, and the liquid soap runs out due to gravity. But I wouldn't try to use soap powder because the door doesn't come open far enough.

spray Manifold had fallen off

Hey parts select, I'm Julia's husband and the repair was a simple remove and replace. Only one screw to hold the manifold together and the mounting hardware that we had to order separately was a snap in piece which was different form the original but went in just fine. You saved me from having to buy a new dishwasher which Julia was more than happy to go shopping for!! Thanks!!

Lower spray arm wobble - poor cleaning

  • Customer: Howard from Catlett VA
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Nutdriver, Screw drivers
  • 3 of 3 people found this instruction helpful
Removed the lower spray arm assembly thumb screw and lifted off the spray arm assembly. The lower seal had disintigrated - couldn't even find any pieces in the filter. After reassembly with the new seal and bearing I turned the spray arm by hand to ensure it was not binding. There was still was, what I would consider, some excessive wobble. I fashioned a shim washer out of some plastic from a Folgers coffee can lid and installed it on the thumbscrew threaded shaft and tightened it all down finger tight - it works very well and now, and no wobble.
I relaced the upper spray arm seal while I was doing the job (both the upper and lower seals are the same part #). I figured it would go out on me eventually, so I might as well replace it while I was doing the lower arm work. Kept the old upper arm seal as an emergency replacement.

Cleaned the filter screen of all debris (it is amazing what collects there over time). Cleaned the stainless tub with some spray Greased Lightning, ran the rinse cycle, and then put a few tablespoons of citric acid crystals in the soap dispenser and ran the dishwasher on NORMAL WASH with temperature boost.
Looks new inside; cleans the dishes, glasses and utensils well (no water spotting); and is nice and quite (like when it was new).
