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. This repair is done on the underside of the dishwasher, nothing to disconnect inside (just remember to remove the baskets). It would be wise to order the motor seal and micro switch that goes with it as they are all cheap parts and easy to swap out during the procedure. Be sure to take... Read more

By: Lg
Part Number: ABT35083801

Do-It-Yourself Stories from Customers like You Water leak   Art D. • Souderton , PA • May 27, 2014

The solenoid that opened the air vent for drying was broken so it was open during the wash cycle allowing water to escape into the air duct. Found the part at SearsParts and AppliancePartsPro, and Sears was $15 more expensive. I ordered on Friday from AppliancePartsPro and selected standard shipping and the part arrive the next day (Saturday). Amazing service. AppliancePartsPro will be my first stop in the future.

The Rack Holder is an OEM part for LG dishwashers. This component is designed to fit on the dishrack and functions as an attachment point for the roller wheels. It facilitates smooth movement of the dishrack in and out of the dishwasher.

  • Unusual noises from the rack area when moving the racks
  • Difficulty in securing the racks within the dishwasher

Do-It-Yourself Stories from Customers like You Noisy dishwasher.   Daniel S. • Fort Wayne , IN • November 04, 2019

I diagnosed the noisy motor by removing the dishwasher from its cubby hole and reconnecting the plumbing and electrical lines. We next did a cycle and I felt the motors during the noisy time. This did not work out due to the overall vibration of the unit. I next waited for the noise again and unplugged some electrical connections. Nailed It. I traced the wires back to one motor, and was able to locate it on the parts diagram. Two days later the new part was in my hands. It took about 90 minutes... Read more

Dishwasher Pump Casing Assembly
Genuine Lg part

Part Number: ABT72909202

Loud droning noise during cycles? A cracked pump casing causes leaks and poor water flow. Moderate DIY repair requires dishwasher removal and reinstall.

Do-It-Yourself Stories from Customers like You Continuous loud droning noise during operation   Scott S. • Littleton , CO • December 17, 2018

I suspected the 'circulation pump' to be the culprit. I could not find a 'circulation pump' so I deduced via the picture schematics it must be the 'casing assembly, pump' I found on the website. I have heard there have been issues with the 'drain pump' so I also ordered the 'case assembly' on this site which is an odd name for the drain pump. Boxes came with just the part inside no instructions or other info. This was fine as I have been diy repairing things my entire life. I made sure... Read more
