The overhead water spinner became detached and fell off

  • Customer: Al from Yuma AZ
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 11 of 11 people found this instruction helpful
First I removed the screw from the top water tube and then the upper screw from the vertical water tube at the back of the dishwasher. That gave enough flex to the tube assembly for access to the area I needed to get to, without having to remove it. Then I removed the old spinner retainer and installed the new one. I then snapped the spinner to the new retainer pin, put the tube back into position, and re-installed the screws -- and I was done.

Turned off power, turned off water supply and diconnected, slid out dishwasher. Removed the spray wand and tilted dishwasher to access the two nuts and disconnet the wires. Removed the two nuts using a socket. Removed the old heating element and replaced with the new one secured with new nuts ( the old ones were fine but since I bought two new ones why not). Pluged the wires back up slid the dishwasher back in hooked up the water reinstalled the spray wand cut on the water and power. Good as new.

The ceramic seal had failed, allowing water to destroy the front motor bearing.

Removed dishwasher from under the counter and took it to my shop. With the washer on its side, I removed the motor, then the impeller and seal. I then disassembled the motor and replaced the front bearing(purchased separately). This required an arbor press. I then reassembled the motor and installed the new seal and impeller. Reassembled in reverse order. Reinstalled under the counter and made conections. Checked for leaks and proper operation.

Poor seal on old gasket caused water to leak during dishwasher operation.

I simply pulled out the old gasket and pushed the new one in with my fingers. I had to trim about an inch off the length with a utility knife. The seal is nice and tight now and we have no more water leakage.

Rinse aid dispenser was leaking

First I removed the screws holding the outside door panel to the inside door panel. Next (at this was the tricky part) was separating the panels. In our model of dishwasher, there is a layer of Styrofoam between the two panel to reduce noise. Unfortunately the Styrofoam is glued to both panels. Separating it without damage was not possible. So it was done with brute force and the Styrofoam broke in several places.

Replacing the dispenser involved removing six screws, disconnecting the wires and popping the dispenser out. The new one went in easily although there seemed to be a correct amount of tightening to do. It was tricky to get the cover back on because the Styrofoam pieces had to go back together like a puzzle.

Once reassembled, I ran the machine and it leaked at the dispenser. So the cover came back off. This time I played with the adjustment of the dispenser, testing it with the outside cover off, to insure that I had a tight, non-leaking seal. Once done, I put the cover back on and we are back in business.

The new dispensers do not have connections for the "Add Rinse Aid" light. They use a visual indicator on the dispenser itself. I simply taped the wire for the indicator light up and left it inside the door.

One last note, on our unit, the outside door panel is two pieces. I needed only to removed the lower portion for this repair. Unfortunately, I removed both and in the process broke the small plastic end on the door latch requiring me to purchase a new one. Bummer. That was a 10 minute repair though.

Lid wouldn't close on detergent dispenser

Thanks to the previous review of this part, I was able to figure out how to do the replacement myself and saving $150 on a service call. The part is super easy to replace. Remove the screws on the door, lift the outside piece of the door up and off the hinges and then unplug the old piece. I had turned off the electricity to the dishwasher to avoid getting shocked. There were 4 hex nut screws holding the part in, removed those & popped out the old part. Installed the new one, put the door back on and the screws, turned it on and no leaks. This part was so easy to replace, even for a 52 year old woman like myself!

My dishes were not being cleaned

I looked up the most common problem with this model and it was the chopper assembly. I removed everything down to this. Sure enough, mine was broken off and the screen was completely clogged with debris. It was not difficult to replace, but it did take me a few minutes to slide it in to place. Ladies, you can do this. No need to call a repairman! Look up the repair manual and see where the assembly is. I had no idea it was even there. My dishes are spotless now.

Dishwasher's "clean" light just blinked - wouldn't run. Repairman came and found out problem and suggested I could fix it myself

Since I had watched a repairman diagnose the problem, it was eash to reproduce how to pull the unit out from the wall and find the faulty part to remove it and replace it with the new thermistor. Two wires to disconnect and connect and repair nearly complete. Pushed it back in, screwed it back to the cabinet and installed foot plate and done.

Chopper not performing

  • Customer: Dale from Oldsmar FL
  • Difficulty: Really easy
  • Time to Complete: 1- 2 hours
  • Tools Required: Pliers
  • 11 of 16 people found this instruction helpful
I noticed some residue in the dishwasher so I decided to clean the chopper screen. I dismantled the screen and spray assemblies and removed the chopper. The chopper was extremely worn and the chopper washer/gasket was missing. I reassembled the parts I removed and as I was placing the screws in the screen assembly I dropped a screw into the impeller well. Since the screws are stainless I was forced to remove the whole motor assembly. Since I had to order a chopper I went ahead and ordered a motor assembly gasket for reassembly. The mistake I made was not ordering a drain valve at the same time for when I removed the valve to clean it the rubber separated. The dishwasher will not function without it. This is where PartsSelect really came through for me. The 2-3 day shipping came in 2 days and the drain valve which was really going to hold me up with standard shipping came the very next day! Way to go PartsSelect! Everything went back together just fine.

Bent the plastic housing down holding the spinner. Slipped the top of clip in slot on top of housing. Attached spinner and bottom of clip by holding top clip and pushing bottom of clip in place. No tools were needed.

Dishwasher basin would fill and then dishwater would shut off. The water was not pumping into the cleaning showers.

To empty the water in the dishwater basin, I pushed the cancel button and closed the door. I then turned the electrical breaker to the off position that supplies electricity to the dishwasher. I confirmed the power was off by attempting to start the dishwaser. I removed the metal plate between the dishwater door and the floor by removing the two screws. I removed the two screws that connect the top of the dishwasher to the underside of the countertop. I shut the water valve that supplies hot water to the dishwasher (mine was located under the sink). I disconnected the drain hose (plastic) by using pliers to loosen the clamp the holds the hose on the outlet of the drain pump (drain pump is much smaller than the pump that needed replacement). A towell is handy to soak up the water that comes out the hoses. I loosened the nut on the water supply hose (this was difficult because of lack of room)using a wrench and pliers. I opened the door on the metal box that houses the wire nuts for the electrical connection to dishwater, and I removed the wire nuts and the screw for the ground wire. Once the white, black, and gound wires were disconnected, I could pull the dishwater out. I also had to pull the drain hose out from the clips on the side of the washer to pull the dishwasher out into the middle of the kitchen floor. I flipped the dishwasher on its back. I removed the single bolt that held the broken pump motor to the dishwasher, and then the motor twisted counterclockwise and I pulled it out. The pump shaft would not turn freely with my pliers, so I knew the motor was broken. I removed the pump end (impeller) from the dishwasher by tapping it with my screwdriver. The impeller end came out along with a metal screen. The metal screen was 50% plugged, so I cleaned it and put it back in place. I wet the gasket on the new pump motor and slid it back in place while rotating clockwise and locking it in place with the tabs. I replaced the bolt that holds the motor in place and reversed the repair procedure to re-install the dishwasher. Be sure to run the dishwasher and look for any leaks. The last step is to replace the metal plate between the floor and door. While I had the dishwasher pulled out, I discovered another problem with the pulleys and strings that prevent the heavy door from flopping down, but I won't include this repair. The pump and motor must have been failing for some time because the dishwasher is much quieter now and the dishwasher is much faster. I am sure the plugged screen didn't help either.

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.

Very loud howling noise during operation

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.

My husband pulled out the dishwasher and removed the faulty part and installed the new one. We found info on the parts source website to assist us. Dishwasher works great!!! Someone from the company we purchased it from had replaced it several years ago, and the seal at the bottom had leaked and the motor had siezed because of the water. We also discoved that the water line was severly kinked in 2 places, so we installed a flexable hose. Now my dishwasher is quiet, fills much faster and all this for a fraction of the price of a new appliance. Would recommend this website.
