Dishes were not cleaned properly, residue

I had removed this part several times before, it had clogged from sediment, so I had practice. That issue was resolved, but I determined the water level during the wash and rinse cycles was low, and the valve appeared to be the culprit. The trick is to remove the valve from the bracket, removing the single screw, and sliding the unit so the tangs on the bracket can be pushed to the rear and then towards the front. When you disconnect the electrical connection, then the valve can be pulled out towards the front for better access and to disconnect, if your supply hose is long enough. That makes swinging the wrench easier. Other wise it is tedious. Make sure to reapply thread tape after reconnecting the supply hose.

spray arm did n't move because it had a crack in the end

First I had to remove the upper dish rack from the dishwasher. This was the most difficult part of the entire fix. I found the screw which holds the spray arm in place, Removed it and took off the old spray arm. Then I replaced the seal and put the entire thing back together, put the screw back in and replaced the rack. Then I ran a load of dishes and discovered the machine works just fine now.

Top Rack Would not Clean Properly

  • Customer: Ben from Lake Zurich IL
  • Difficulty: Easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Pliers

1) Remove the racks

2) Unattach the feed tube the runs from the bottom of the dishwasher tub along the back to the top (this is the grey plastic tube that the top rack sprayer plugs into). This is done by unclipping the tube in two places, one stainless clip is in the back of the tub and one stainless clip is on the top of the tub.

3) After the tube is loosened from the clips, give the tube a 45° twist clockwise (relative to the bottom of the tub) and then pull up. This should remove the entire feed tube and bottom sprayer assembly.

4) There are now 4 stainless steel torx screws visible on the bottom of the tube. Remove the screws using a torx driver. Remove the grey plastic "gear looking" piece that was held in by the screws by pulling straight up.

5) On the left hand side of the tub you will see one more (smaller) torx screw. Remove this screw and then with a pair of plyers, give the housing piece that was held on with the screw a tug straight upwards. There is a post sticking straight up that will help you do this.

6) The grinder assembly is now visible, and in my case, completely jammed with paper. Pull the grinder and screen out of the groove it is sitting in.

7) Place the new grinding and screen into the groove. The grinder blade will have to be pull back (toward you) so the grinder coupling teeth can properly engage with the motor coupling teeth. This may take some fiddling.

8) once the grinder is installed, reverse all the steps starting at step 5.

Part that attaches the sprayer arm was broken.

Removed first part of the broken part from the top rack of the dishwasher from below.

Removed the screw from the bottom of the sprayer arm to release the second half of the broken part.

Threaded new part in sprayer arm and replaced screw.

Attached part to top rack of dishwasher from below. This part was difficult. (The part appeared to be a little larger than the original.) It was a two person job, one person pushing down on the rack and the second pushing upwardand inward on the part it click to click it into place. Dishwasher now works great.

Dishwasher won't turn on

  • Customer: David from Centreville MD

The cycle select buttons on the top of the door worked and would light, however, the power button did not function and did not light. The faulty part ended up not being the control board but the control panel, which included the power button. I spent a good amount of time troubleshooting the problem until I figured this out. The part number was (8531257) Panel-cntl.

Very loud howling noise during operation

  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Pliers, Screw drivers, Wrench set

Replaced pump and motor. For the price of the products individually, it only made sense to do the whole thing. As someone else mentioned, much easier to remove the dishwasher and turn it on it's side to remove/replace. Disconnect 3 fittings, 3 stop devices and remove. Other than getting about 20 cuts on my hands from all the metal, it wasn't bad at all.

Dishwasher was making a loud noise during the wash cycle and it was getting worse with time. The bearing nearest the pump impeller was failing.

Disconnect the water supply, the drain line, and the two screws that go up into the cabinet frame, then pull the dishwasher out from under the counter. Tip the unit onto it's face and the main pump/motor is facing up. Turn off the power then unplug the electrical connector from the motor. Remove the single bolt at the base of the motor then turn the whole motor ~1/4 turn counter-clockwise. A firm pull will remove the motor/pump at this point.
The new motor/pump has a new seal. See that the arrows on the pump volute and the motor frame are lined up before inserting into the housing. The new motor/pump slides into the housing easily and a 1/4 turn clockwise will pull it in tight. Re-install the locking bolt and revers the rest of the steps to get running again.

First research then troubleshoot
Removed
1 Upper rack
2 Lower rack
3 Lower Wash Arm and Strainer Parts
4 Upper Wash and Rinse Parts
5 Accumulator assy.
6 Motor shield
7 Inlet protector (most difficult)
Noticed blade was broken off chopper assy.

Most difficult step was to remove Inlet protector
After removing two torx screws (#15) used small pry bar to lift inlet protector from position. Not easy to accomplish with hands alone. Inlet protector fits tightly into position.

The replacement of the gasket was simple and required only a flat-head screwdriver to push the rubber into the groove around the opening of the dishwasher. Took only about 15 minutes and the door is a tight fit now. I wish I had replaced the gasket 6 months ago when it first started coming loose when we opened the door to the dishwasher.

First I shut off the breaker for the dishwasher. I had to remove the 6 screws that hold the top part of the dishwasher door to find the panel with the fuse. Then following the instructions that came with the new fuse I cut the wires from the old fuse to remove it. Next I installed the new fuse and attached the wires and then replaced the screws. Turned the breaker back on and everything worked great.

Discovered through internet that it may be a bad chek-valve, Opened washer up and removed inside covers. Actually found that the chopper assembly was bent and non-functional.

Removed drain hose to ensure no blockage in drain. No blockage, then removed drain pump cap (where drain hose attaches to drain pump) with allen wrench. Push tab in on drain pump and twist counterclockwise, drain pump came off. Reversed to attach new pump and it works.

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.
