When I read the book it said that the HE stood for Heating Element. You can easily get to it from the bottom. (leason learned after getting to it from the top) Test the element for continuity. Second Test to see if power is being fed to Heating Element with dishwasher turned off. Expensive Lesson Learned After Burning up three Heating elements (including the original) The Circuit board went bad and was sending power to my Heating element with dishwaher off. It was burning up the heating elements in about 30 seconds. $150 dollars of parts and shipping dishwasher is still not working. Waiting to see if LG will honor there 5 year warranty on the Control Board.

Be sure to order extra rolled with axles. The clips the snap on to the top rack are delicate and I broke two of them putting them in place. Be sure to snug them on slowly and carefully, it seems that the soap scum buildup on the rack creates additional friction. This friction makes you need to push the part on harder, and when you do it snaps on too hrs and one side of the clip will break off.

Check the motor and discovered roughness when you turned the shaft. I assume there was a bearing problem. I ordered a new motor from part select and upon the replacement washer is working great! Thanks part select, my part arrived in a timely manner and you guys saved me approx. $500. Thanx again. Richard Sansom

removing the dishwasher from under the counter I accidentally broke the mounting braket, to investigate/discover the door lift cord had frayed and broken. Parts were easy to locate and the costomer service was friendly. Installation was a breeze and perfectly intuitive. Not a Problem. thanks for being there, hiring a repairman would have been expensive.

pulled the dishwasher out, removed the side panel. It was very easy to replace the connector once the dishwasher was out and the side panel was removed. There are about five screws to remove the side panel. I replaced the unbroken connector on the other side since I had the dishwasher out.

The connector that provides counter weight for the door snapped and the door would flop open, it weighs a lot

Uninstall dishwasher screws. Lay dishwasher on its side. Remove bottom plate. Remove old drain line. install new line. Test for leak. The trick was figuring out that I could only access the line through the bottom of the dishwasher.

Unit would not start up

Conclusion was that either the control panel or the noise filter (an electrical fuse apparatus)was bad. Disconnected the water line, turned off power, and pulled unit out from cabinets. Determined that voltage was going into the noise filter (white harness) but almost no voltage coming out (red harness). Ordered noise filter. Hardest part was removing old noise filter from dishwasher frame without removing the whole unit from cabinet and turning upside down.One screw holds the part in the frame. With power off, I used a very small ratchet with phillips screw driver. Pried unit out with screw driver on side to the panel front. It has a retaining tab there.Installation was the reverse. Instead of putting screw back the way it was originally installed, I screwed it in from the outside of the frame. Much easier and just as solid. Tested unit with power on. Hooked up water line. Works great. Note: LG dishwahers have a high repair rate and that this part has a high failure rate. This LG unit was two years old. Never had to fix my 15 year old Sears dishwasher. It still works to this day. (I gave it to my daughter.)

First, PartSelect is great!; fast,& accurate. 1. Inside the dishwasher: remove trays. Remove (A050) lower water sprayer from bottom by pulling up. Remove (F191) top sprayer assembly by pulling away from clip holders. Remove (M110) by removing the holding screws. This part cover the whole sump and has kind-of an open screen circling the unit. Now you will see the white plastic impeller (M120) which is attached the the motor with one Phillips head screw. WARNING. The Phillips head screw (holding the impeller in place) is a REVERSE THREADED SCREW. Turn the screw CLOCKWISE to remove it. Then remove the impeller from the motor shaft. Underneath and outside the washer: Remove the bottom plate. Finally remove the motor by unscrewing the four holding screws and electrical wiring.
