UNIT WOULDN'T WORK. "CLEAN" LIGHT BLINKING

  • Customer: PAUL from ESTES PARK CO
  • Difficulty: Really easy
  • Time to Complete: 1- 2 hours
  • Tools Required: Nutdriver, Screw drivers

The unit had power, but the controls would not work. The "Clean" light was blinking. I first replaced the control unit, no help. I then used the "Just Ask" and was told the problem was the heating element and/or the Hi-Temp thermostat. I replaced both those and used the re-set code pushing the "Hi-Temp/Air Dry, Hi-Temp/Air Dry" buttons. That did it. Easy parts to locate and replace. It took longer pulling the unit out and putting it back than it did to replace the parts.

I removed the 6 torx screws that hold the control panel on the top part of the door, from the inside, removed the large plastic cover from the control board, removed the 2 big wires that go to the thermal fuse...tested for continuity and foung the fuse faulty...ordered a new fuse kit, reversed the procedure and it works like new.

Dispenser worked intermittently

  • Difficulty: Easy

First, I brought in my electric screwdriver and torx bit set. The screws holding the door are torx type. I removed the screws holding the door cover allowing access to the (6) hex head screws holding the dispenser in place. Raising the plastic flap covering the dispenser I removed the (2) electrical plugs from the solenoid. Using my elec/screwdriver and a 3/16" socket I quickly removed the old dispenser.
I cleaned the gasket area with some 409 and a paper towel and slid the new dispenser into place. I used a 3/16" nutdriver to tighten the screws. I tightened the screws in a cross pattern in (3) stages so as not to squeeze the gasket out of position. Screw slowly and the screws will bottom out when the proper gasket tension has been achieved, don’t over tighten.
I closed the door and ran the dishwasher in rinse cycle checking for leaks. After a couple of minutes and no leaks I pushed the cancel and drain button. I folded the plastic cover back down over the dispenser and reinstalled the outer door cover tightening all screws with my electric screwdriver and torx bit. I opened the door and filled the rinse dispenser.
We've used the dishwasher several times since the repair and the dispenser has worked fine.

Water was not being pumped out of the dishwasher

This site is wonderful..., thank you. Especially thanks to Nanette's detailed experience. The thing that gave me the most problem (and apparently Nanette, as well) was removing the lower round cover of the chopper assembly. Finally, some one on the internet identified the trick...put needle nose pliers in the screw-hole and pull-away. It came right out. Wish I could acknowledge the source but now can't find it.
Actually, the check valve was good, but I replaced it anyway. It was 10 times the trouble to replace than the drain pump. Wish I had started with the drain pump. By removing the drain hose, I stuck my finger in the hole and discovered the problem: the impeller was off of the pump and lying in the bottom of the drain. It was a simple thing to replace the pump. Press down on the locking mechanism and turn it to the left. When it was off, I could see that the check valve was in place and not a problem. (Of course by that time, I had already replaced it.) Good luck.

No water out the spray arms; first thing you'll notice is the top rack not getting clean.

Took racks out, loosen screw on top and back then twist feed tube to right and whole assembly can be removed. Now you should be able to see some torx screws; remove those and then remove the piece they were holding down, from there you'll see another screw, remove it and the piece and so on until there are no more screws. Now there is the food chopper cover that needs to be removed; mine was stuck there. You should notice some ribs underneath that allow the water to be sucked in while keeping really big pieces out; I got a pair of channel-locks, opened them all the way and was able to slip one of the pieces under the cover and pull straight up, once off you will see the chopper covvered in food. I cleaned mine off and it looked good, but when I put it back and stuck my finger down teh discharge tube and turned the pump, the chpper did not turn. when I put the new one in and did the same test it did turn. If the chopper is still fits in the slot, it can be cleaned and put back and work for several washes while the part is shipped. I went ahead and changed the check valve since I had it opened which is just to the right of the chopper(all you can see is a little slit and some black rubber). Use some needle nose and pull it out. I would not do this unless you plan on changing it, I pulled mine out to look at it and when I put it back so I could order the parts the dishwasher never drained properly. When you compare a new one with an old one you will see what I mean, you can drop a new one right in but the old one you will have to force in (gets water logged over time and expands). This job is very easy and a lot cheaper than a new DW...and your wife will be impressed, so do not be intimidated.

Dishes still dirty after full cycle. problem developed gradually over 2 week period

Several hours to diagnose problem: Removed all the plastic water distribution tubes to top rack and found no blockages. removed lower water jets, drain screens using star driver on 6 screws. still could find now blockages. decided problem had to be in pump mounted below unit so completely disconnected unit and removed from under counter. Upon removing lower plate below door I discovered a plastic pouch containing an excellent trouble shooting guide with complete dis-assembly instructions and parts breakout diagrams with P/N listings! First thing I discovered from this was that the chopper assembly was hiding under a plastic cover just under the filter screen I had already removed. The trick was to press down on the right side of the plate to get it to pop up and reveal the chopper. The whole chopper assembly slides out without tools. I found the strainer plate behind the chopper blade totally plugged as the blade had broken off the plastic drive shaft because the retaining knob on the end of the shaft had broken off. I was able to drill and tap the shaft and install a SS machine screw with washer to reassemble the chopper blade on the shaft. Not expecting this "Joe Maggee" repair to last more than a few cycles I went online with the P/N and googled PartSelect. Placed the order and chose std delivery over 2day or next day since I expected the repair to last for the week. I put everything back together and the first load came out perfect! This was Sunday afternoon. Tuesday the part arrived at my doorstep! 15 minutes and the new part was in. My "Joe Maggee" repair is now in the junk drawer awaiting the next pistachio shell that gets run through the washer.

I called an experienced plumber, who balanced and installed my new dishwasher properly, using the brackets I ordered from Parts Select, after an INEXPERIENCED plumber had tossed the factory-provided mounting brackets out with the shipping carton. Relief!

Dishes were not getting clean / Low Water Pressure

  • Customer: Greg from Virginia Beach VA
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers
  • 19 of 21 people found this instruction helpful
Started as dishes not getting clean and I observed that the top arm was not spinning and there was very low water pressure coming out of the jets. After making sure the water level was up to the bottom of the heating element and making sure the jets were not clogged I checked the filter and chopper. It was a little tough to get the cover off of the chopper but once I did I could see that the chopper scraper was broken off and the shaft was broken. The screen was all clogged up with stuff. Ordered a new assembly and put it in making sure to compress the spring and make sure the gears lined up. Now it is running great.
I think the Kitchenaid is the same as the Whirlpools.

Pump Motor fwd bearing worn out

  • Customer: Thomas from Massapequa NY
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers, Socket set

My dishwasher motor was getting very noisy lately and finally died altogether. (the fwd bearing and seals had worn out. There was a small pile of what looked like white sand under the motor from the wear) I removed the dishwasher from the counter after turning off the power at the breaker box. I then turned the dishwasher on its side. The pump motor is removed by first removing the electrical connector, then loosening the retaining bolt and twisting the motor counterclockwise about a quarter turn. The gasket required a little force to become unseated from the housing but not to bad. Wiggle and pull! Be sure to take a look at the alignment at this point to facilitate reinstallation.To install the new motor, align the mark on the impeller(small delta) with the mark on the motor. Insert Motor into housing and turn clockwise one quarter turn till retaining bolt hole is aligned. Install retaining bolt. Be sure to note the position of the stainless steel screen where you insert the motor. Place it back in position before installing the pump if it is disturbed. I lubed the oring with vaseline prior to install also. The new oring was diffrent and did not feel very tight when i installed , but there were no leaks and the dishwasher is running like new. Partselect had the part at my door the next day with no upgrade in shipping charges and I will use them in the future. This forum helped me choose them and made the task easier to do. Hope this helps you as well.

Lower Dishwasher rack replacement

I ordered the part and was hoping to just take out one rack and put in the other, there were NO instructions or even a diagram of the rack. There was a fold down rack that was not attached and a few parts that I have no idea what they are. This was very discouraging. The main thing is that the rack is quite a bit lighter than the original one so I doubt it will last very long. The price was more than I wanted to pay but I didn't have any options in replacement parts.

As I pulled out the old rubber gasket I noticed there was a flat side and a curved side, this is how the new one must go. When I put in the new gasket in I just made sure the flat side (faced out) and it really was very simple. It just fits inside a grove, very easy to install. I compared the to parts (old and new) they were exactly the same shape and length.
I was very impressed with the web site navigation and layout. I was able to zoom in on pictures of the part and there were exact measurements of dimensions.

Checked grinder and cleaned it several times, adjusted blades. Dishes would be clean for approx. 6 cycles, then would not clean. Placed dishwasher on its front and removed the motor. Removed grinder and impeller which I found to be worn so that the blades would not turn on the grinder which caused it to collect food particles. The impeller locks in easily.

Via your web-site I was able to download the step-by-step screen-shot pictures. I was really surprised on how easy the detailed photo screen shots made the repair really easy! Thanks for making this repair a piece of cake. If I should ever need additional parts for any of my home appliances I will certainly order my parts through PartSelect.

Following advice given on website by previous customers I was able to remove 6 tork screws and check the fuse which was okay. Proceeded to remove the control board and found significant burning on the bottom side. Ordered a new board online Sunday night, shipped Monday by two day Fed Ex, arrived Weds. morning and installed it in less than 10 minutes. Fair price, excellent service and shipping. Thank you and I would buy from you again.
