WM3988HWA (ABWEEUS) LG Washer - Instructions

I followed the video on the PartSelect web site for this repair and it went just fine. I also replaced the drain hose while I had everything apart. Thank you PartSelect, same day shipping. Arrived within 3 day's and your video was spot on.

Followed the video instructions provided.

Change the thermistor

Viewed two (2) on-line video's for bearing replacement. Produced a 40 item "punch list" as to action to perform following video. Followed sequencing of video's. Noted a 10mm and 17 mm socket needed, used 3/8 drive sockets. Also noted that a "deep Socket" of unspecified size used to aid in removal of nylon pins attaching (3) shock absorbers. Found that 1/2 inch sized (SAE) socket in my 1/2 inch drive socket set fit in the confined space nicely. Did not need the "deep sockets" (3 plus inch overall length) rather a normal sized 1/2 drive socket worked nicely to depress the nylon pin retainers. During reassemble replaced outer tub gasket, checked bolt torque six (6) times over 45 min. to assure complete seating.

I BROUGHT UP THE YOUTUBE REPAIR VIDEO AND FOLLOWED IT STEP BY STEP AND WORKED OUT GREAT THANKS

Pull the washer away from the wall to get behind it. Unplug the electrical power cord from the wall. I removed the top cover by unscrewing the 2 screws on the back of the washer. Slide the cover back about 1-2 inches towards the back of the washer and then lift the cover up and remove. It might be a little tight to slide back, you may need to wiggle the cover side to side or give it a good smack. The water inlet valve is directly at the top inside of the washer. I saw a slow leak dripping from the hot water inlet valve onto the back side of the drum. Turn off the water supply valve at the wall and then unscrew the supply water hose from the water inlet valve at the back of the washer. Disconnect the electrical connector and water hose from the inlet valve inside the washer. From the outside of the washer on the back, remove the screws holding the water valve and lift out the valve. Install in reverse order.

removed two screws from back of front load washer slid the top back two inches and pulled up removing the top.Turned the water off at the shut off . Used the pliers to remove the clamps on the hose to replace. Put the new hose on with new clamps. Un screwed the two screws holding the inlet valve and removed the hose and clamp. Put the new part in and put the hose and clamp back on then put the two screws back that hold the inlet valve.Total time to unpack the parts and install 7 minutes. All I did was google it on youtube and order the parts from this site which only took 2 days and tah dah .

Remove old one and replace. Just make sure it is all the way on and secure or you will have a huge mess on your hands.

Some screws, some clamps. Easy and straight forward. unplug machine, turn off water, disconnect water hose, unscrew top of machine (2 philips head screws), disconnect clamp from valve (use a towel for remaining water), disconnect wire, unscrew from place holder, remove entire valve, work backwards from there.

Unplug washer!!! 1. Remove retaining ring around rubber gasket with flat head screwdriver. Just slightly pry off and it will easily come off. 2. Just peel back rubber gasket on the side that the lock is on. 3. remove 2 screws from the front off the lock assembly. 4. gently reach in and lift the little plastic clip holding the wiring harness and lift straight off. If the clip is lifted it might be a little tight just use even steady pressure to pull off. 5. Reverse these instructions to replace. Note: replacing the retaining ring on the rubber is a pain. The spring has to be in the bottom. Using a couple of flathead screwdrivers you can wrangle it back in place after awhile. There is a tool that looks like a large reverse pliers that may make it easier. Anyway thats it, pretty easy. There is a youtube video that shows all of this.

UNPLUG WASHER.Unscrew 4 screws holding silver plate at back of unit. Remove plate to expose inside of unit. Locate drain hose at bottom of washer tub. Hose connects at front drain, bottom of tub, and at rear at the pressure sensor. Front and rear simply slide clamps down by grasping clamp tabs and sliding clamp off connection point. Disconnect from tub bottom by loosening main clamp with Phillips screwdriver and pulling downward. Have a towel handy as there will be water in the hose, and it will pour out when removing it from the unit. Installation is the reverse of removal. ATTACH THE HOSE ASSEMBLY TO THE DRUM FIRST, THEN FRONT, THEN LASTLY REAR. This order is the easiest way, otherwise you will spend extra minutes trying to get the tub connection to seat properly. Plug it back in (duh), then you're good to go for another 4 years or so until another hole wears in the hose. I have performed this repair on 3 different units, with 4 years being the average lifespan of this part.

We drained the water from the washer via the tiny hose/filter located at the lower left corner of the washing machine. The unit was then pulled away from the wall, unplugged and the hoses disconnected. At this time, we used the wet dry vacuum to suction the water that remained in the drain hose. We tilted the washing machine back until the front of the unit was 18 inches or so off the floor. We used the foot stool to hold the washer up in the air so that we could work on the pump. Replacing the pump was as easy as removing a few screws, unplugging the electrical connections and removing the faulty pump assembly from the plastic housing. (Be sure to mark what connector goes in what terminal). Re-assemble. Re-connect. You are ready to go. It took more time to ready the washer than it did to replace the part.

ordered part from Part Select and it was here very quickly,but the part came damaged (not the fault of Part Select). I ordered another one and PartSelect had it here the next day. I watched the video on how to replace it and it was very helpfull.The particular part I replaced (pump motor) does not seem very durable. I will buy an American made washer the next time I need one. I will use Partselect in the future and recomend it to others.

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.)

The problem ended up being the pump motor which discharges water from the washer. I figured out this was the problem after trying several things. I determined the motor was fine when it was empty. With the unit turned off, if you can rotate the tube with a quick spin and it lights up, probably this is OK. Then I tried to run it again and it went about 1/2 way through the cycle and stopped and started humming again. So I started emptying out the water, which I noticed was about 5 gallons which is way too much. so once empty, I took the pump off by turning unit on side. There are two hoses with hose clamps, and a few screws. Be careful to mark which wire plugs onto which side of the pump. One is brown and one is black. If you take the pump housing off, with the 3 screws, you should be able to pull the motor apart. Mine had water and scum from the wash in it, which was a dead give away that it was the problem.
