Dishwasher leaking; got AE error almost every other wash
The inside gasket deteriorates over time - However replacement is easy. the main thing you have to remember is after you remove the old gasket, install the new one starting at the middle top of the tub and work your way down both sides. Also, don't push the gasket all the way in...only enough to hold in place. When you close the door the gasket will form a better seal around the door.

Coating on upper dishwasher rack wore through in some places.
1. Slide out old rack assembly.
2. Slide in new rack assembly.

Not so much a "repair" because buying the whole assembly instead of just the rack means you don't have to do anything more than just slide out the old rack assembly and slide in the new one. It comes out like any cabinet or dresser drawer.

old rack's coating had split and began to rust
Took a picture of original rack to make sure the new rack placed correctly. Old rack came out without need for tools and the new rack went in with ease after making sure it was facing in the right direction.

There was a leak in the bottom left corner.
I am 77 years old and got it all on but the corners did not want to go in so I had to call my grandson and he got them in. It still leaked on the bottom left side. It is getting old (11 yrs) so I decided to get a new one. It is actually pretty simple to install, but it does take a little strength.

Front door would fall open without resistance.
The repair took right at one hour. Repair length of time will depend on what all you have to disconnect to get your dish washer out so you can remove both side panels where you will be able to access the door springs, etc. There is a door spring on each side and I recommend replacing both connectors cords while you have the dishwasher out. Mine were both broken. One thing I noticed when doing my repair was that the bracket that is on the bottom of the door was not aligned properly to the small pulley that the connector cords travels under. If yours is out of alignment you will be able to tell once you get the connector cord installed. I used heavy pliers to bend the bracket slightly inward so the connector cords rides in the center of the pulley and not off to the outside as before. This may be why mine broke in the first place. After part replacement, reinstall the door panels and put the washer back in service. There are also YouTube's of this repair so you can see what you are getting into. Basic repair.

Our dishwasher door would drop open and land on our feet.
My husband was able to slide the dishwasher out, and quickly replace the old connector assembly for the new ones. The old connector assembly had broken at the “rope”. Now the door opens slowly and is as good as new.

Dishwasher would stop during the cycle with nE code
This was my first time repairing a dishwasher. I watched YouTube on how to remove the dishwasher from the cabinet. Afterwards, I removed the bottom of the dishwasher while it was laying flat to get to the motor and micro switch. The only difficulty I had was getting to the motor which required taking the bottom section off of the dishwasher. I could not get an appliance repair company to work on an LG dishwasher. My only option was to repair the dishwasher or bought a new dishwasher. Therefore, my wife and I decided to , make an attempt to repair this one with a backup plan of buying a new one. Luckily, we were able to fix this one within two hours.

This was a $999 dishwasher. We saved the cost of a new dishwasher by taking the time to fix this one.

door latch broken
same as in the video , but the double red wire is on the wrong terminal you have to break the plastic housing on the dishwasher and put it on the first one next to the white wire .if you hook it up the way it is the dishwasher wont work and when you open the door the dishwasher turns on . watch the video real close when it gets to the wire connections you see the double red wire goes over one pin to the one next to the white wire . works fine after that.

Wrong part
The parts are wrong and am trying to return them. There was no return information included with delivery. Calling the Customer Service number for assistance did not work.

I would just like to return these rollers and would like a return address.

Thank you!

Door would fall to floor
Very easy just took out two screws that held the dishwasher to counter top.Then pulled dishwasher out just far enough that both door cables are exposed.The hardest part for me was getting the spring stretched enough to clip on.This was a easy installation for most people.
