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.

We simply removed the old gasket which was corroded, cleaned up the hard water buildup, and popped the new gasket into place. The problem was fixed! No more leak!

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.

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.

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. . .

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.

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.

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.

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.

Removed the old gasket, without tools, and fit the new gasket into the space, making sure it was in the groove correctly all around, job done, works great. The ordering of the gasket on this site was easy and the shipping time was amazing, one day. Would use this company again, and recommend to anyone needing parts that wants to do repairs themself. I am sure saved a whole lot over hiring someone, and got the job done sooner also.

The latch was becoming very difficult to open being almost 10 years old

  • Customer: Frank from Parker CO
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver, Screw drivers

I had to remove the screws around the door frame and remove the side panels that attached the inside cover from the interior of the door. Once I removed it I could then unscrew the top cover that then allowed me to remove an inside cover for the internal electrical connections and the door latch was then open for repair. The electrical connections to both sides of the door switch and holder assemby had to be pulled from the assembly and I was then able to remove the assembly and the door latch. The new door holder and latch handle had to be connected to the electrical wires and inserted back into the door and the initial process was reversed to reinstall.

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.
