Door spring had broken; door would fall open

  • Customer: Sue from Weymouth, MA
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers
  • 9 of 9 people found this instruction helpful
Removed the bottom panel on the unit (2 screws hold it on) and pulled the dishwasher out about 4"--after turning off electricity to the unit. Removed the broken spring and the old linkage and replaced them with the new parts. Pushed the diswasher back into place, and replaced the bottom panel. Turned on the electricity and the diswasher door is "good as new." This is quite simple to do; just takes patience.

Water leak underneath dishwasher

  • Customer: Richard from New Orleans, LA
  • Difficulty: Really Easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Nutdriver, Screw drivers, Wrench (Adjustable)
  • 9 of 10 people found this instruction helpful
Unplugged dishwasher, removed the 2 wires clipped to the heating element, removed both cracked nuts, replaced with new nuts from PartSelect, clipped on wires, plugged in and did a test cycle. Based upon service quote from Best Buy, I saved myself $125.00 for just the call out, not including parts and labor.

No Water Circulating in Wash or Rinse Cycle

  • Customer: Rod from Bandon, OR
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Pliers, Screw drivers, Wrench (Adjustable)
  • 9 of 10 people found this instruction helpful
Removed the dishwasher from under the counter, and ran to diagnose the problem. Drain pump ran, but circulating motor did not. Ordered the replacement circ pump / motor assy, and slid the washer back in its hole.
When the new motor arrived, I slid it back out, disconnected everything, and drained the water from the bottom. Then I tipped the washer on its side, removed the old motor and installed the new one following included instructions. I did have to use the new wiring harness, and found the new one had only two leads where the original had three. I connected the blue and white leads, and left the original green loose.
All in all, it was an easy repair that could be done by anyone with a basic set of skills.

Heater Element Covered in Mineral Deposits

  • Customer: Chad from Cypress, TX
  • Difficulty: Really Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers
  • 10 of 14 people found this instruction helpful
Our dishwasher sat in a warehouse for a year after our move from CA to TX. When I finally installed it, there was some sort of white mineral deposit that had built up on the heater element. I didn't notice it back in CA. I tried to get as much as possible off but it kept building. So I purchased a new heater element. It's been in for a few weeks and my wife thinks the build up is happening again.
To Repair;
Unscrew the dishwasher from the counter. They'll be one or two screws attaching the dishwasher on the underside of the counter.
Pull the washer out carefully.
Remove any dishes and the bottom rack.
Tilt washer on it's side.
Remove wire connections to heater element (They slide right off but make sure to remember which one goes where)
Unscrew the nuts that are holding the element on. I used some pliers. It wasn't difficult.
Remove old element and replace with new.
Reverse order.

  • Tools Required: Pliers, Wrench (Adjustable)
  • 9 of 11 people found this instruction helpful
Removed the bottom covering on dishwasher and then ran it to figure out where the leak was coming from. Noticed it was dripping off hose, but not actually leaking from hose.

Unplugged dishwasher and slid it out from cabinet area (be sure to turn off and disconnect water supply)

Followed delivery tube up side of dishwasher to top of tub and noticed reminents of where water ran down side of tub.

Loosened delivery tube by plastic nut inside of tube and removed. Noticed gasket was partially depleted.

Ordered new gasket, replaced and put everything back together. (Be sure to use teflon tape on water source fitting and tighten firmly). No leaks

Water leak behind kick-plate

  • Customer: Larry from EDWARDS, CO
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers, Socket set, Wrench set
  • 10 of 15 people found this instruction helpful
Water had been dripping for quite some time causing the floor boards to warp and buckle causing the door to no longer align. Water drip could be seen coming from the motor area. Ordered the O rings and replaced. Get Motor & Pump schematic Pub to visualize how parts fit together. I recommend getting motor (~$90)which comes with O rings (~$50 for O rings alone) because, as it turns out, the leak was in motor. I will post repair process in separate posting.

dispenser cap latch broke

I foloowed the others who repared the same item. I really appreciated their help and input. The only thing I would add is when they said that you only have to remove the bottom 2 screws on the inside of the dishwasher door they are absolutely correct. But don't look on the very bottom of the door like I did. They are on the inside of the door, facing inside. The bottom screw on each side. Thanks for all the help.

DO NOT BE TEMPTED TO REMOVE THE INNER DOOR SCREWS!!!!! I was and added about 10 minutes to a repair that should take less than 5. The lower door gasket just pulls out the bottom of the door. No tools required, just pull it out. The new one just pushes in, no click or anything, just make sure it bottoms into the groove.

This was too easy. I pulled out the bottom rack, spread apart the two clips which are at the bottom of the spray arm with my fingers and pulled out the old broken spray arm. The damage was visible. Then I took the new spray arm ( which looked different but still fit nicely) and gently pushed it into place. Done!

Broke nubs off of stem when cleaning

  • Customer: Glen from Chicago, IL
  • Difficulty: Really Easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 7 of 7 people found this instruction helpful
I took the bottom parts out. This can basically be done without tools. You need a phillips to unscrew 3 screws to remove the stem. Then easily replace with the new one. Putting the spiny washing part was kinda weird because I was afraid to break the nubs off again. I took the whole bottom carriage out so I could see better, pushed down kinda hard and twisted the right way (figure out which way needs to be twisted before hand by looking through the bottom of the stem).

Dishwasher wouldn't drain!

  • Customer: Adriane from McKinney, TX
  • Difficulty: Really Easy

I already had the dishwasher pulled out (remove the two screws from under the counter holding the dishwasher in place) The drain was located on the right side at the bottom very easily removed after taking out the two screws and removing the tubing. Attached the tubing to the new drain pump, made sure clamps were in place and then screwed the screws back in to hold the drain pump into the bracket. Ran the dishwasher once before pushing it back in to make sure there were no leaks. Had a leak but completely unrelated to the drain pump.....I had to replace the hot water supply line the next day, also SUPER EASY. Pushed dishwasher back in and replaced the two screws into the brackets that hold the dishwasher in. Kind of disappointed that I had to replace these things since the dishwasher is just over a year old, but PartSelect made finding the part super easy and they were by far the BEST PRICE! Thanks again! Only suggestion is I wish that it would have come with directions...but I figured it out pretty well!

Upper rack not being cleaned

  • Customer: steven from Walnut Creek, CA
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Pliers, Screw drivers
  • 8 of 11 people found this instruction helpful
This was pretty easy. It was a guess as to the problem, but there much debate , if the water isn't moving it had to be the pump, right?. So i replaced the circulation pump. 2 screws on the top and two trim screws on the bottom, and it slides right out. Then UNPLUG IT.. Take the screen out of the bottom on the inside and make sure you get all the water out or it will end up on the floor when you tip it on it's side. The directions were ok, i looked over them briefly but didn't use them. tools were, phillips srewdriver, torx driver (pump bracket srews) wire stripper/crimper (for the plug adaptor) and a heat gun, (for the heat shrink tube for the crimp connection). Overall it was pretty easy. the pump was made to be easy to replace. 45 min and back in action.

Dishwasher was leaking out of small gold nut

  • Customer: Emily from Kyle, TX
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers
  • 7 of 9 people found this instruction helpful
The nut was split down one side, so I first tried to sauder the nut back together. Saudering never goes well for me anyway, but I couldn't get a good enough seal around the nut to make it fit tightly. Then I had to cut off the clear plastic shield to get down in there, just before realizing you could just pull the white wire firmly and it would come loose from the nut. All I had to do then was unscrew the original nut, and screw on the new nut. Then, luckily I had mistakenly ordered an extra clear plastic shield and could replace the one I had previously cut. Dishwasher now runs like a charm!

Replace sump gasket

  • Customer: Greg from Rockwall, TX
  • Difficulty: A Bit Difficult
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver, Wrench (Adjustable)

#1 rule, make sure you valve off the water before removing any hoses. Remove wire trays inside dishwasher and then pull out dishwasher far enough to disconnect water line and power cord. Remove center piece and screen covering sump inside the dishwasher. Turn dishwasher on its side and remove hoses to sump and pump. Disconnect power to sump pump. Loosen retaining nuts that secure the sump and remove. Replace old gasket on sump with new. Turn dishwasher upright. Be careful with placement of new gasket when reinserting sump so that the gasket doesn't come out of position and the sump is centered properly. Secure with retaining nuts from bottom. Reconnect power connector and hoses to sump. Pour enough water into the dishwasher to verify gasket doesn't leak... look with flashlight under dishwasher for signs of water dripping from sump. Reinstall screen and centerpiece in sump inside the dishwasher. Reconnect water line and power cord. Run through wash cycle while monitoring for leaks under dishwasher. Reinstall wire trays.

Piece of cake as long as you get the gasket installed properly and the sump centered correctly... do not overtighten the retaining nuts or it may force the gasket out of position when the screen is secure with the center locking piece over the sump.
