Dishwasher not draining

  • Customer: Darrell from Snellville, GA
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver, Screw drivers
  • 10 of 10 people found this instruction helpful
It was my first time repairing a dishwasher. I was a little worried. I also wasn't sure about how to remove the drain pump. Well, the hardest part was just getting the dishwasher out from under the counter. I did find a crimp in the drain line that probably contributed to the original pump going out. I fixed that, removed the old pump by removing one screw holding a stablizer bracket and twisting the pump connection. The original bracket is needed, so I removed it from the old pump, attached it to the new pump and reversed the removal process and secured the pump by reattaching the stabilizer bar with the single screw. I then slide the dishwasher back under the counter. Runs great. Easy repair. The part was shipped and delivered on time. Very impressed with the process and will order my appliance parts from you in the future.

Dishwasher wasn't cleaning well, especially top rack

  • Customer: Casey from Wadsworth, OH
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers

I wanted to get the dishwasher cleaning better and thought that maybe the accumulator needed to be replaced. I figured that I'd swap out all the spray arms as well, just for good measure.

I needed Torx screwdrivers (T15 and T20, I think - not 100% sure on that) and patience because there's really quite a lot of screws to get the accumulator out. Finally got to it and it didn't look damaged, but replaced it anyway.

The spray arms are easy - they just snap in except for the lowest one, that had a plastic nut. I ordered a replacement nut just in case I broke this one (you know how that goes) taking it off. Well, it took pliers, but it came off ok.

In the end, my dishwasher is happy and cleans much better now.

dishwasher leaked

First replaced rubber seal around door, which did not stop the leaking.
Then ordered insulation foam strip and replaced old one, which fixed problem. Put new strip over the old one because tub was slightly warped.
Very pleased with order speed and cost.

Dishwasher heating element bad

  • Customer: Gary from Indianapolis, IN
  • Difficulty: Difficult
  • Time to Complete: More than 2 hours
  • Tools Required: Pliers, Screw drivers, Socket set, Wrench (Adjustable), Wrench set
  • 10 of 12 people found this instruction helpful
I could not reach the heater element nuts from under the dishwasher so had to pull out the dishwasher. I removed the screws around the front of the dishwasher and pulled it about half way out before the water inlet pipe and the electrical wires stopped me. I shut off the water, unhooked the copper pipe, and unhooked the electrical wires (shut off circuit breaker first). Pulled the dishwaser out so I could remove the element nuts and wires to the element. Removed the old element and installed the new one - the old nuts would not fit. I went to a local appliance parts store and found that my element is no longer made. I had the correct replacement element but you need to order the nuts also. Luckily, the local store had a small brass nut that worked. Reattached the electrical wires to the element, pushed the dishwasher half way in, reattached the water inlet and electrical wires, pushed the dishwasher all the way in and scewed back into the cabinets. All is well now and the dishwasher is working much better.

I unscrewed the door panel. removed the plastic cover protecting the dispenser. unscrewed the dispenser (6 screws). I removed the old dispenser and put the new one on and put it all back together. It was pretty easy.

Detached Water Distribution Manifold

  • Customer: Harry from Bensalem, PA
  • Difficulty: Really Easy
  • Time to Complete: Less than 15 mins
  • Tools Required:
  • 11 of 17 people found this instruction helpful
The original brackets that hold the water distribution manifold to the back and top of the tub came off the "X-shaped" plastic posts on the tub walls. That caused the upper wash arm to sag down into the travel of the upper dish rack and was broken off when the rack was pushed in.
I bought 2 new brackets and a new wash arm. The new brackets had a smaller aperature than the originals and fit tightly onto the plastic posts, holding the manifold firmly in its proper location. Replacement of the brackets and the new wash arm took less than ten minutes and required no tools!

The adapter still needs another union to fit to the faucet . I have tried Ace Hardware, Lowes, Menards, Danco, Price Pfister and many online plumbing supply and hardware stores and am not able to find a union or combination of unions to fit.
I need an adapter with two 55/64-27 male ends.

Small / slow leak at bottom corner of dishwasher door.

After examining the door and main seal around the dishwasher I thought everything looked okay. I looked online to order a new seal anyway and discovered from others that the leak was probably the insulation strip inside the door rather than the seal around the dishwasher. I ordered an insulation strip and it arrived a couple days later. I removed the seven screws of the interior door cover and disconnected the electrical. After removing the old insulation strip and installig the new one I reconnected the electrical wiring/plugs, put the door cover back on, and reinstalled the screws. Total time was about 15-20 minutes and the leak stopped. It was very easy and saved the cost of a repairman or a new dishwasher. I'm very glad that I "listened" to others and went with the new insulation strip.

Drain pump noisy

  • Customer: Scott from High Point, NC
  • Difficulty: Really Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers

As others have described once you slide the dishwasher out and tilt it for access you simply remove the discharge (use something to catch the water), torx screw that secures the bracket to the unit, and twist counter clockwise until the pump is free from the drain tub. Reassemble in reverse order

Upper Rack not Cleaning

  • Difficulty: Easy

First I read all the reports for not cleaning properly already listed on this site. I had to replace the docking station with flappers. When I removed the station I lost the flappers down the water delivery tube just like Jon said I would in his repair post so I removed the water distribution assembly fished out the old flappers and snapped in the new.
But then I figured I might as well check out the accumulator while I was in the tub anyway - I had read that you need Torx screwdriver bit, which I had, undid the screws, pulled out the accumulator screen which was about 80% clogged, discovered I need a new chopper blade and my impeller is disintegrating, put it back together and lost ten minutes looking for the three screws I had incorrectly put in too soon, and now it is cleaning a packed full load like it was supposed to do.
**I love this site - I went to the virtual repairman and it listed every problem I had with this appliance in the order they happened (door latch broke years ago). - I think I am going to look up stuff that I own so I will know ahead what could go wrong with them.

And absolutely NO DUCT TAPE was used in this repair.

Motor would not turn the impeller, no wash pressure.

Not a bad repair once you diagnose the problem. Took me three tries to figure it out. Just make sure you follow the instructions. I used an allen wrench to hold the motor in place while tightening the part onto the motor shaft, this way I didn't have to remove and flip the dishwasher to do the repair. The good news is the replacement part I needed was metal instead of plastic, thus I should never have this problem again. I don't understand why it was plastic in the first place but all of my appliance problems seem to be made to fail after several years of service.

Lost the faucet adapter

  • Customer: Victor from Demotte, IN
  • Difficulty: Really Easy

I had to replace the faucet in the kitchen sink orignnally. However since I use a porteable dishwasher, its hose connects to the kitchen faucet. The new faucets aerator is threaded differently than the old so that the dishwasher adapter would not screw in. I had misplaced the adappter kit that came with the dishwasher last year, so I ordered the adapter from partselect.com. when the part came a few day it was a simple as screw out the old aerator, screwing in the new adapted and then putting the modified aerator from the old faucet back in so that the dishwasher can be connected as needed.

Door latch on the dishwasher broke.

First I opened the breaker on the dishwasher removing power from the unit. Then I removed the Torx head screws on the cover on the back side of the front door. Then I pulled off the stainless steel sheet metal panel which exposed the door latch. Then I unplugged the electrical connectors to the two micro switches on the assembly, next I plugged in the connectors on the new latch assembly and postioned the latch back on the mounting holes. Replaced the stainless steel sheet metal and put the screws back.

All that was broken on the old detergent dispenser was the door but the door can not be ordered without buying the whole detergent/rinse aid assembly. When I got the new item I just removed the old door and replaced it with the new door that I had taken off the new one. I still have the new detergent/rinse aid assembly that I can keep if I need to change it in the future.
