Lost the faucet adapter

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.

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.

Small / slow leak at bottom corner of dishwasher door.

  • Customer: Adam from Acworth GA
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers

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.

Broken wheel, broken fingers

  • Customer: Todd from Topeka KS
  • Difficulty: A Bit Difficult
  • Time to Complete: 30 - 60 mins
  • Tools Required: Pliers, Screw drivers

The rear right caster (wheel) under our fairly new portable dishwasher broke. Upon looking up the part, I discovered that it did not bolt into place, meaning that the exterior skin of the dishwasher did not have to be removed and that more than likely I could fix it myself.

The replacement wheels from Partselect were nicer quality than what the original was and showed up just two days after they were ordered.

However, getting what remained of the broken caster out was frustrating. I am not unhandy around the house, having put in two new bathrooms and a staircase.

But after yanking and prying on the broken caster for 20 minutes (slamming my fingers into the floor every time the pliers slipped), I could see where most people would give up and call a repairman. Finally, with help from small pry bar, the broken caster popped loose. Thankfully, putting the new in was as simple as sliding it into place.

Unfortunately, after all that work, we discovered the new caster was slightly taller than the old, leaving the dishwasher with a distinct wobble that my wife said was unacceptable. She, of course, had not been repeatedly introducing her hand to the floor.

I had ordered two replacement casters, thinking that another of the originals might break. But getting the second one out proved just as difficult as the first, even with the help of the pry bar.

After much cussing and kissing of finger booboos, our Maytag dishwasher is as good as the day we brought it home.

Detached Water Distribution Manifold

  • Customer: Harry from Bensalem PA
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins

  • 7 of 10 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!

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.

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

Broken Dishwasher Door Latch - Assembly Replacement

  • Customer: Gail from Sharpsburg GA
  • Difficulty: Really easy

Being a fairly technical female, I decided after Internet research to replace this part by myself. It could not have been easier - even after reading several Internet horror stories. I believe the major difference being I replaced the entire assembly, not simply the latch.

You need a hex-head allen wrench to remove the inside cover of the dishwasher door, and some sort of pliers to remove the old unit. I used vice grips since I am a wimpy girl - they worked nicely (this took the longest time).

Step by Step:

Turn off the power to your dishwasher.

Remove the door screws and carefully lift it to access the door latch assembly.

Remove the old door latch by unplugging the black and white electrical mechanism. Pay close attention to which side the black and white connections are removed from for reconnection reasons. This is where I had to use vice grips. It took a bit to "unplug" the old latch assembly.

Once the old latch assembly is removed, position the new latch assembly and reconnect the electrical source.

Carefully reposition the door and replace the screws.

Turn on the power.

Run a short cycle (I used rinse) to make sure that the unit was replaced correctly.

Can it be any easier than that??

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.

First turned off power to dishwasher. Then, I removed all the screws on the dishwasher door. Removed old plastic door latch from wire assembly piece. Pressed on latches for square small wire boxes connected to wire assembly piece to be able to handle wire assembly plastic piece without attachment to dishwasher. Tried to snap door handle to wire assembly plastic piece, but didn't seem to fit - was too tight. Checked for discussion online and found that it required heavy pressure to snap in place. Used pliers to clamp down on outer plastic on wire assembly piece to squeeze fit door latch plastic hooks in place. This was difficult, but with heavy pressure finally managed to snap in outer hooks. Then with difficulty snapped in inner hooks. Was afraid of breaking new plastic piece, but all worked out well. Door has never opened and closed so well!!

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.
