FIRST I TURNED OFF THE POWER GOING TO THE MACHINE!!!! Then I removed the top rack by removing the (2) end caps on the front of the rack glides first then lifting the rack upwards and out. Next I removed the bottom rack which slid out easily. I then removed the lower spray arm that was held in place by the plastic turn-screw portion of the lower spray arm support/hub. I turned the screw a few times and the spray arm was released. I then released the feed tube assembly that was held in place by (2) clips; one clip was on the back panel of the tub (above the probe area) and the other clip was on the top panel of the tub (before the upper arm spray). Then I turned the entire tube feed assembly a quarter turn to the right so that it was possible to separate/unsnap it from the feed cap on the bottom. After the feed tube was moved away I was able to access all (4) screws that holds the accumulator in place. I used an allen wrench to remove those. After the accumulator was removed I saw two screws that was holding the 2-part protective cover of the chopper assembly. The small cover came out easily, the round cover took a little jiggling and fussing until I figured out how to pop it out. The chopper was revealed when the cover came off and I found it to be very warn and a bit bent. I pulled it out by pulling it upwards and forward towards me. At this time I also removed the valve check. To my surprise it didn't look like the one that I bougth to replace it. It was missing the round disk portion. I fished around thinking it may have somehow fallen off, but I didn't find anything. I put the new one in, disk-side down. I then put the chopper assembly in place and put everything back together again. I'm not 100% sure that it is completely back to normal. It seems to leave significantly less debris than before, but I noticed that there is more water on the bottom of the basin now. So it may not have been my only problem. If anyone has experienced the same thing I would really like to know

There was a noise coming from the dishwasher that sounded like a loose part. Kind of a loud rattle.

  • Customer: Robert from Youngsville NC
  • Difficulty: A Bit Difficult
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers

I had to remove the baskets, spray assemblies (no tools needed) and disassemble the section of the pump that contained the chopper assembly. (removing three Torx screws)
I had to remove a part of the old chopper that had gone into the pump, but I was lucky that a magnet grabbed it so I didn't have to disassemble the pump.
The total repair was not difficult. The only problem was access (hands in the way while repairing difficult to see) and compressing the spring on the new chopper while trying to slip it into the groove.
The parts came in three days and they fit perfectly

I removed broken mount by gently bending tabs, pressed new mount into upper dish rack, attached the spin arm and secured the mount with the screw.

A snap---it took less than 2 minutes after only a two day turnaround from ordering the part to receiving it at home..

Fantastic service. Thanks!!!!

water not heating

The repair was easy. Getting the unit to slide out from under the counter was more time consuming.
After water and power is disconnected, tip the unit over onto one side to gain access to bottom. Look for two white composite plastic posts (insulators) about 2" long each with a single wire inside. Remove the two wire connectors then unscrew the insulators from the old heating element using an adjustable wrench. Inside the box remove the two metal element supports and pull out the old element. Clean and dry the area in and around the openings where the new element will be re-inserted. Carefully place the new element into the holes with the included new rubber washers. Re-install the two metal element supports on the inside of box. On the bottom, re-install the two insulators to the ends of the element, do not to tighten too much to avoid over compressing the rubber washers which could cause premature cracking. Reconnect both wires and check continuity from the door mircro-switch (white-violet) lead to the (white-red) lead on Electronic Controller connector #1 (P6). The circuit thru the element should be good if the Multimeter reads 10-35 ohms. Put the unit securely back under the counter and run a test wash. Works fine now.
I do recommend, if don't know how to use a multimeter or are concerned about accessing the electronic control box; contact a professional.

Remove upper tray and spray arm. Remove two screws retaining pipe for upper spray arm and overhead. Unscrew retainer on top of lower spray arm and remove. Gently rotate the upper feed pipe clockwise until pipe can be removed from lower pipe. You may then remove the lower pipe and bearing housing where the seal is. Reverse order for reassembly. I also replaced upper spray arm bushing. Very simple, remove one screw and the arm will come out.

dishwasher not spraying water

Repair man said I needed a new pump and would cost $350 to repair. This dishwasher was only 5 years old and we only use about once a week so didn't think the pump was gone. Went on this website and read some stories. this model has a mini garbage disposal with a chopper and screen which gets clogged up and prevents water from circulating. You can clean the screen without removing the dishwasher. Remove the cover plates on the bottom with 4 screws and the smaller cover plate underneath. Remove screen, clean and replace. If the chopper is broken you can order a replacement for $21. There is another story on this site with a lot more detail so I wont repeat here.

Motor starting making a terrible racket after installation 15 months earlier

  • Customer: David from Andover MA
  • Difficulty: Easy

Be sure to shut off power at circuit breaker and disconnect drain and water supply. Remove the dishwasher from the cabinet, lower it on its side. Remove three electrical connections from motor to various sensors. Remove three plastic wedges that secure the motor gasket to make a tight seal. The motor pops into the body of the dishwasher for removal. The replacement motor goes in just as you took it out. It took two people to set the motor right to ensure the good seal on the gasket for re-installation. Then turn it back upright and secure it in place. Couple suggestions, be sure to have ample towels around for leakage from water and drain lines. Be sure to cover the bottom of the dishwasher during disassembly and reassembly of the wash manifold. I dropped a screw in there and it took me some time to fish it out.
All in all, it went well. Don't pay a plumber for this job. I'm a clod and if I did it, you can.

I took out the old one and started in the lower left corner and threaded it all around the edge to make sure the placement and length was correct. Then I came back around with a plastic spatula to firmly seat the gasket into the groove. Worked perfectly and havent had any trouble since!
