WM3987HW (ABWEEUS) LG Washer - Instructions

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.)

Followed the instructions that a fellow DIYer posted in PartSelect and a few I watched on Youtube. Pull out the detergent drawer, remove the back screws, slide the top off, unclip the control board, unplug Power & One more switch so that I could move it aside. Take the gasket retention wire off the door gasket & tuck it inside. Remove the screws in the bottom & top. Then slide the front panel, including the door up (not easy) and out. The part received was only the pump motor so I had to take a few pictures before so I knew I got it together right. Remove drain houses, pump screws, slide pump back and remove pump. A few more screws to remove the pump from the housing & replace with new pump. Put it all back together. It works! It only took about 45 minutes

Used a screwdriver to carefull lift the top of washer. Reached in and unplugged old assembly from wir harness. Unscrewed old one (2 screws) from washer screwed in new one connected it to wire harness. Closed top of washer and plugged it in and it was ready to use. I am a 53 year old female and had never done this before. The repair shop wanted $150 to install part plus the part cost more from them. I' m sure a guy could do the job in 15 minutes or less.

Did the repair entirely from the back.- 4 screws back cover comes off. Once you see the Bellows it is obvious what needs to come off and there are other videos on the net showing this. The main things I did differently were 1) Leaned the washer forward and placed 3 2x4 blocks of wood under each back leg. This allowed me to reach under the washer with one hand, and through the back with the other. You need both hands in there ! 2) Uninstalling is easy with just pliers. But on the way back in, I used a pair of Locking Pliers to keep the circular clamp squeezed as much as possible. That seemed the only way to get the bellows back in. Another option would be to switch to screw on Pipe clamps instead of the spring clamps.

After checking for blockage on the drain hose and checking on any blockage on the bottom left corner filter and not finding anything i decided to open the machine. Everything suggested a broken drain pump
ITEM
PS3579318 Drain Pump and Motor Assembly which is located on the bottom left corner also and it attaches to the bottom left corner filter. And voila! The machine did not work! Now started throwing a FE code and it would not fill up. Well, the new pump was stuck! All i had to do was to stick my fingers in the bottom left corner filter orifice and move the fan like devices that make the new drain pump work, that did it! Be careful not to do it while the machine is pluged in, those plastic blades may hurt your fingers. To reach the drain pump you have to take the top, control board and front (door and gasket) of the machine off, about one hour labor.

Hardest part was getting the correct part. Due to some glitch somewhere there was a mix up in the database for the correct pump number. This unit has two pumps mounted to the same housing. One is a recirculating pump and one is discharge pump. I ordered the discharge pump and kept receiving the recirculating pump. Discharge pump is LG PART#4681EA2001T and recirculating pump is LG PART #4681EA2002H Once in hand the install went fairly smoothly. Removed top - two screws on back of unit. Removed control panel with one screw on upper right inside corner, associated plugs and snap clips. Removed soap tray and drained water through filter tube. Removed screws in front of filter. Using Vise grips stretched spring from around front seal. Removed screws holding front of washer to top frame (2?)[accessed after soap tray removal]. Pump assembly located in bottom left, removed associated hoses, Marked wired colors on pump housings and removed. Removed assembly. Unscrewed pump, installed new pump and reversed procedure to reassemble. Struggled mostly with replacing spring around front seal. Stretch it as far apart as you can as you "roll" the spring in and then massage the seal to get the spring into correct position. Definitely a doable repair. Good Luck.

The repair went well and your parts are easy to find. This is the second time I have used your services and both times have been great. Your parts are at great prices and your delivery is a lot faster that one would think.
Thank you

First we unplugged the machine. Then turned off the water and disconnected the hoses. Pulled out the machine and laid it on its side to access the themsistor located on the drum. (No, you do not have to remove the control panel at all to replace this part) The thermsistor is clearly seen with a flashlight. There were plastic ties holding the wires of the thermsistor so we used small scissors to cut the ties. Then unplugged the old thermsistor and plugged in the new thermsistor and used a regular bag twist to secure the wires. Repair complete and the machine is back to normal. Thank you Part Select.

Opened rear compartment of washer and observed problem with drum shaft slipping inside of plastic motor assembly. The plastic teeth used to secure drum shaft were worn down. The part I needed was sent as an assembly but should have been sent separately for a much lower cost? The new part looked like it was of a sturdier design. All in all I saved hundreds of dollars repairing the washer my self. The woman I spoke to on the phone was really nice and very helpful.

removed top, removed 2 screws, replace part. did not fix problem, the real problem was the water inlet valve, works great, easy fix. thanks

Removed lid (top of washer), then ran a cycle in normal to identify the failed component, then noticed the water inlet valve assembly for the hot water was leaking, used my pc and went to website Part Select and found to failed part on the parts break down item, then ordered the part, the part "Valve Assembly Inlet" for the hot water arrived 2-days later, replaced valve in less than 5-minutes, disconnected push on electrical connector, unscrewed the valve assembly inlet and installed the new valve assembly inlet, very easy

1. Unplug washer. 2. Shut off water supply (hot and cold). 3.Remove hot water hose at washer inlet. 4. Remove the 2 plastic pieces that hold the washer top to the washer body by removing the 2 retaining screws. 5. Pull the top back to remove and set the washer top off to the side. 6. Unclip the electric harness from the inlet water valve. 7. With your pliers, loosen the clamp on the water inlet valve discharge hose and remove the hose from the valve. 8. Loosen and remove the 2 screws holding the inlet valve to the washer body. Install new hot water inlet valve and follow steps in reverse. Check for leaks before plugging washer back in. Run washer and check for leaks. Note: Excellent video available on You Tube. Consider replacing both the hot and cold water connecting hoses during the repair if they are old.

Unplug Washing machine first. Then remove 2 screws at the back of the top cover. Slide the top cover back then lift and remove. Unplug electrical connector @ inlet valve and remove water lines 1 going in and 1 out of valve. Remove 2 screws holding assembly in place then install new valve assembly and all other components in reverse order.

pulled off top of washer to get at the inlet valve disconnect two hoses take two screws out and then you put it back together the way you took apart and your done

Simply took hose off from inside machine and replaced it with new one. The tore one had a stopper on one end that wrapped to front machine; inside filter compartment. So I put stopper on the other end of new hose and wrapped it to it's holding spot in filter compartment.
