Do-It-Yourself Stories from Customers like You Door spring pulleys broke on our lg dishwasher   Leigh C. • Bemidji , MN • March 22, 2015

I looked up my unit and reviewed the schematic drawing online at Appliance Parts Pro. Once receiving the parts, I Pulled out the dishwasher and removed side panels - didn't even have to disconnect anything. Removed broken parts and replaced them with the new - took about 10-15 minutes start to finish. Easy cheesy! Owning LG appliances I'm thankful to have found a resource like Appliance Parts Pro!

Do-It-Yourself Stories from Customers like You Lg dishwasher “ne” or “ue” error code (vario spray arm).   Dimitri T. • Cranston , RI • February 26, 2019

This was a very simple repair. It was done in about an hour. It involves disconnecting the dishwasher, emptying the water from the inside, taking it out and flipping it over, and replacing the diverter motor.
