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

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.

Do-It-Yourself Stories from Customers like You 0e drainage error code   Christopher L. • Walnut Creek , CA • February 24, 2015

So all of a sudden the dishwasher stops working, "0E error"on the panel. Did some google searches and found that it might be the filter, which I did not know needed to be changed, or worse, the motor. Took the filter off per online tutorial (easy) and mopped up all the stagnant water. Poking around, I find the small rubber check valve that has broken. Had to fish it out with tweezers. Long story short, it was not the motor and I doubt it was the filter. It was this $1.87 rubber drainage... Read more

I replaced the upper nozzle guide, nozzle shaft and upper spray arm. I also replaced the pump gasket for good measure. Top rack dishes had not been cleaning properly.

Do-It-Yourself Stories from Customers like You Missing brackets and screw hole cover   Brian S. • Ashland , MO • March 15, 2016

Thanks to LG NOT sending the parts THEY say are included with the dishwasher, I had to buy them in order to install the appliance. I sure hope the LG appliance performs better than their customer service. Very simple fix....bought the EXACT items needed from AppliancePartsPros.com and in just a matter of two days, had the parts needed. Amazing! Excellent experience. The fix was attaching the brackets to the cabinet and screwing it to the countertop. Also just popping the screw covers... Read more

I replaced the dishwasher circulation motor. I also replaced the impeller assembly, although it turns out that was not necessary. Actually replacing the motor was straightforward: Remove the upper and lower racks. Turn off the breaker and water supply. Disconnect power, supply water and drain hose. Slide out the dishwasher. Inside the dishwasher, unscrew the two screws holding on the bottom rotating sprayer and remove the sprayer, unscrew the one screw holding the little metal bracket and... Read more

Do-It-Yourself Stories from Customers like You Loud grinding sound motor rattling   Marvin L. • Sandy , UT • November 09, 2014

My project involved replacing the sump assembly and main motor on my LG dishwasher. The parts arrive in about 2-3 days. Wow, FAST! With the help of videos from LG I knew what to do. The trick with the whole project was ensuring that I transferred ALL gaskets from the old sump assembly to the new one. I missed transferring one around a sensor, then did not get the gasket around the pump motor properly. Once all those were correct all leaks stopped, new motor is whisper quiet (all I hear now is...

Do-It-Yourself Stories from Customers like You Leaky lg dishwasher   Tom B. • Perrysburg , OH • October 09, 2015

I ordered a tub seal to fix a gasket that let go in our LG LDS4821BB. Once I tore it apart to get the gasket out (little trouble) I also found what has made this DW stink for the last year. I needed to also replace the filter unit in the bottom of the tub and clean the heater area. I ordered the filter the same day I got the gasket. Both arrived WITHIN 48hrs of my order. Wow!! What more can you ask for? Great prices too. Both parts were replaced by removing a total of 12 screws and easy... Read more
