heating element split open

  • Customer: Hadley from De Leon TX
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Nutdriver
  • 9 of 9 people found this instruction helpful
I took the bottom cover off and pulled off 2 wires and removed 2 plastic nuts. I removed the old part and removed the O rings from the old part and installed the new heating element. Replaced the plastic nuts and the two wires. It was very simple. The hardest part was lying on my back to get to the wires and nuts.

Racks were rusting, pieces braking off and rubber coating was peeling.

Was extremely easy to remove that existing rackings(upper and lower), install the new racks and snap in the new spray tower. It now looks like we have a new dishwasher. We are hoping that it will last another 10+ years.
We will recommend your site to friends.

loose top basket/

  • Customer: Wanda from Bay Shore NY
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers
  • 13 of 22 people found this instruction helpful
I had two problems with the dishwasher. The top basket was loose, but the main problem was a plastic part inside the bottom assembly.

The part was backordered, so I re-ordered it through Sears. They said it would arrive in two days. Theirs came in two weeks, and their customer service was terrible.

Your "backordered" part came in two days, even before it was supposed to come had the part not been back ordered. I am delighted with your customer service and your company.

The illustrations on your website were excellent. They helped us not only to identify the part, but to diagnose the problem.

This was my first purchase through your company and if I ever need parts again, there is absolutely no reason to go anywhere else.

You have an excellent company, and great website! I bookmarked your page for future purchases.

Upper washer arm holes plugged up

  • Customer: STEVE from RAYTOWN MO
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 8 of 9 people found this instruction helpful
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

  • Customer: Bill from Morganville NJ
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Socket set, Wrench(Adjustable)
  • 7 of 7 people found this instruction helpful
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.

Pump gasket had deteriorated with age and causing odors.

The dishwasher is well engineered to perform this work.

Remove the bottom two panels to provide access and visibility to base of pump motor.

Locate plastic pump locking lever and push toward rear of DW to unlock pump from DW.

Inside the DW remove basketsand spray arms. Revove screws holding cover over pump motor and remove cover.

From below raise pump motor and support with block (piece of 2x4 worked well).

insde DW, removre old gasket, clean well around pump and botom of DW, install new gasket.

From below remove block to drop pump motro back into place, and re-tighten locking lever by pull toward you.

re-assemble inside componets, run through a rinse cycle to test for leaks and replace bottom panels.




I

Failing to complete any of the cycles properly, repeated "click" heard from control unit.

  • Customer: brian from myersville MD
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 9 of 13 people found this instruction helpful
It was initially unclear precisely which part I needed. I called PartSelect customer service and the agent was extremely helpful and able to quickly advise me on the correct part.

Installation was straight forwared. I used a torx screw-driver to remove the screws holding the inside-door planel. There are wires attached so this needs to be done with care.

I then removed a thin plastic film cover the control assembly. The control assembly is held firm by a screw and is also "snapped" in place. There are obvious tabs which can be spread to allow the assembly to be lifted out.

Each of the wire harness can then be removed from the control assembly.

With the new control assembly in place, the wires can be reconnected very easily. The assembly board itself is well marked enough to determine where each of the wires connects but really, the connectors for each harness is unique so pretty difficult to not get right.

Replace the plastic film and door cover and you are back in business.

I had previously gotten a quote from Sears to do this work and it was over $200 works of labor. Go through PartSelect I not only saved about $40 dollars on the part itself, I also saved $200 on a fairly easy repair that I could do myself in under 30 minutes.

Handle Ends Broken

  • Customer: Glen from Bala Cynwyd PA
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 7 of 8 people found this instruction helpful
1. Removed the torx screws around the metal liner
2. Pulled back the metal liner being careful not to disturb the connected wires
3. Pushed scissors into the latch actuator (part that pushes into the the catch on the dishwasher cabinet) until it sprung into position to simulate closure - you can't get the handle on easily without doing this.
4. Placed the end tab of one side of the handle into the slot on the side of the latch actuator.
5. Applied pressure on the other side until it snapped into place.
6. Pulled on the handle to release the catch.
7. Replaced the torx screws.
8. Works perfectly!! (until it breaks again)

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.

Dishwasher leaking water

  • Customer: Marvin from Republic MO
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Pliers, Screw drivers, Wrench(Adjustable)
  • 8 of 12 people found this instruction helpful
Pulled the dishwasher out. Determined that it was leaking from the air/water inlet. Ordered the seal and replaced the seal by turning the inside cover counter clockwise while holding the outer water inlet. Replaced seal and installed water hose. Put dishwasher back inside cabinet and leveled. If you don't try to fix it yourself, It could cost more then what it is worth.

I accientally busted the old rinse arm, while I was trying to put in the filterguard with bottom spray arm jet

  • Customer: mary from sturgis MI
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Socket set
  • 6 of 6 people found this instruction helpful
I took the bottom rack out of the dishwasher. I then took the filter guard and bottom spray arm out. Then I took the screws out of the filter guard to get to the rinse arm. I took the filter guard off, took the old rinse arm out and put in the new one. Have to make sure it is completely resting inside there. Then I put the filter guard back on. Put the screws back into the filter guard, put the two arm seals down around the rinse arm, put the bottom arm spray with guard back into the notches, put the screw top on so it can screw back in and the dishwasher is ready to go. Just make sure that you don't have a lot of soap built up, it will not clean the dishes right nor will the spray arms move. I had to call my appliance person out, and I have so much built up from soap, that I had to order a new filter guard and top and bottom spray jets. I now know to switch back to powder or liquid soap, because the tablets make a huge built up of soap... I have these parts on order now. In the meantime, I am cleaning out the jets with dishwasher magic and vinegar while I am waiting for my new parts. I now know how to put things back together so when I have this happen again I will know how to do it to save me the 63.00 office call and parts. I am happy that I know where to get my parts when I need them or break them by accident on trying to put my dishwasher back together again. Thanks.

Lots of noise and wouldn't pump

  • Customer: Joe from Franklin NC
  • Difficulty: Really easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver
  • 6 of 6 people found this instruction helpful
I first removed the washer arm. Be careful because it is screwed on with the large center plastic piece with right hand thread. That allowed me to take the arm and disc off.

Next I took 6 screws loose with the allen wrench. This allowed me to get to the filter ring. I removed it and that allowed me to get to the three screws holding the discharge. I used a 5/16th socket to remove them.

A plastic disc that was part of the upper pump came loose and caused the noise. I replaced the upper discharge housing (with upper pump as part of it) and upper discharge housing gasket and reversed the order to reassemble.

The exploded diagram was a terrific help

Squeezing the handle did not open the latch

  • Customer: Robert from Ocala FL
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins

  • 6 of 6 people found this instruction helpful
After unplugging the dishwasher, I opened the door which required more pulling effort than it should. There were 10 screws which fasten the inside panel to the door. 2 of these are located next to the latch. I used my drill driver with a star bit. By carefully separating the panel from the door, I was able to see the inside of the latch mechanism. The plastic handle had 2 ears that had snapped off. It was fairly easy to remove the broken handle and replace it with the new one. All that was necessary then was to replace the 10 screws and tighten them. It seems to be fine now.
