I took out both wax motors - tried switching the motors on the rinse dispenser and soap dispenser but they were both dead - new motors from partselect arrived fast - simple installation if you have the torx screwdriver for the door inner panel.

No pressure in Spray Arms, no washing action

  • Difficulty: Difficult

The hardes part was to remove the retaning nut (#34 on the diagram). There isn't enough grab on it and it is quite flimzy. Be prepared to butcher it if necessary. I resorted to wedging a screwdriver between the top flange of the nut and the spray arm and that gave me torque I needed to undo it. Luckily, the nut survived and could be reused.
Once the nut is off, everything else is pretty straightforward, just pay attention what goes after what and in what orientation (take notes if you must, however, I did not and got away with it). My machine has not been serviced in years and there was calcium deposits everywhere. If your machine is just as bad as mine, I strongly suggest to remove everything that can be removed and give it a nice vinegar bath or use other products designed for calcium removal (ask your wife what she is cleaning the bathroom with, it will most likely do). Bottom line, the cleaner the parts are, the better it will pump.
In my case, it was the calcium that eventually killed the impeller #14 and made it spin on the shaft (no pumping therefore).
Inspect all the parts for heat / wear damage so you put one order for everything you might need.
Secondly, the screw #12 that holds the impeller #14 on the shaft is a tiny screw and it is originally secured with a threadlocker. Make sure that the internal thread in the shaft and the screw are absolutely dry before applying loctite.
Thirdly, there is a plastic ball that sits in the cavity in one of the disk-like part (not shown on the diagram). Do not loose it and make sure it is put back.
That's pretty much it. Once properly cleaned and repaired, the machine washed like brand new. Pretty good for less than $50 investment in parts and a week downtime. . .

Leaking

  • Customer: L W from Manning SC
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Nutdriver, Screw drivers
  • 9 of 10 people found this instruction helpful
I first changed the dispenser door latch grommet, which was very eazy except for the left side nut screw which was a little awkwaed to get to with the nut driver. Not a big problem but difficult enough that i stripped the threads (plastic) and had to get a larger screw which is working fine so far. Since the grommet didn't stop the leaking although it was obvious it was leaking from the soap trail. I ordered the gasket and got it very promptly put it on and guess what. Still leaked some. I discovered when they installed the dishwasher the door appeared to be warped. To fix this there are two door tension springs under the bottom panel. By adjusting these with a log screw driver problem finally solved.
It is good to have not only a great place to get parts but the idea's from others are terrific. Although this washer is 15 years old it looks new and now acts new. Thanks so much for good service and advise.

Not getting clean dishes; filter kept getting cloged.

  • Customer: Joe from Titusville NJ
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Socket set

After removing parts, cleaned both upper and lower spray arms, blew out lead to the upper arm, and started to install the new parts.

Unfortunately, the Pump Housing Filter was still cold (freezing weather during shipment and left at the front door) and when I started to bend it into shape it broke in two places. So I tolk the old filter and some Lime away and slowly cleaned it with soft brush to open 95% of the holes.
Once ready it was installed along with the other new parts and the dishwasher works very well.

Simple homeowner repair.

Removed two lower panels using nutdriver. Ran washer through a rinse cycle, to determine for sure where leak was coming from (under door on left). Examined the door gasket and observed buildup of lime deposits and a general depression of the gasket through years of use, especially in lower portions. Removed the old gasket observing how installed. Cleaned out groove with Lime-away and toothbrush. Washed clean using water in a squirt bottle. Dried things out using paper towels, and then pressed new gasket into place, starting at lower left. Readjusted the gasket to fit precisely end to end. Shut door and ran a drip free load.

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.

Water was pouring out of dishwasher door

I googled the simptoms online, and found that the most common cause for a door leak was the door seal. I purchased the seal online from PartSelect.com. Two days later, the part arrived. I pulled out the old seal and pushed in the new one. No tools required. That fixed the problem. While looking at the parts diagram, I noticed that my dishwasher didn't have the water deflectors installed. I don't know if they were ever there. They were cheap, so I ordered them online and slid them into place in less than 10 seconds. Again, no tools required. Dishwasher runs great, no leaks.

The detergent cup cover would not open and the rinse aid was not dispensing properly

I removed the seven screws from the back panel of the door (special tool) and seperated the back panel from the front. My wife held the back up and I removed the two wax motors (detergent cup and rinse aid), which were clipped in place. I had turned off power to the dishwasher, so I simply unplugged each wax motor from the wiring harness, plugged the wax motors in and clipped them in place, making sure that the wiring harness was put back in the same place. Then I put the back panel back on the door, turned the power on and tested the repair. The dishwasher worked perfectly. Thanks to PartSelect for helping me solve the problem. The parts arrived in two days!

Small / slow leak at bottom corner of dishwasher door.

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.

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.

Took off bottom plate for access. Slid part that holds bottom of spring forward so I could reach it without pulling dishwasher out of position. Hooked spring to bottom attachment, then connected door spring linkage to holder that is attached to the dishwasher frame. Adjusted the tension with the tension screw and buttoned up bottom plate.
