WM3988HWA (00) LG Washer - Instructions

During my troubleshooting, I removed the bottom to access the drain pump. I had to cut some wire ties so that I could make removing the wires easier. After checking the pump and putting everything back together, I determined that the pump itself was bad. Pump impeller should not rotate freely! After receiving new part, I installed it relatively easy. I didn't have to remove the bottom since there was enough room through the access hole. Just make sure to make where wires go before removing old part.

It was so easy. i searched my model it brought up this site and the most common problem popped up without my even asking and recommended the part. i got it one week later and it was so simple to fix. a repair man wanted three times the part price to come to my home twice and would have had to wait longer. you guys were very helpful

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.

1. Remove spring-loaded clamp assembly. 2. Partially pull out the large rubber gasket near the lock switch assembly to gain access to the lock switch assembly. 3. Unscrew two screws holding the lock switch assembly. Carefully separate the connector from the lock screw assembly and replace it with the new part. Reinstall in reverse sequence. Ensure that the electrical connector is fully seated unto the lock switch assembly and the connector latch is fully set against the lock switch body. Also make sure that the large rubber seal is fully seated around the door opening to prevent water leak. Restarted the washer and everything worked as before.

The machine was making a grinding noise instead of draining. I spoke with the LG rep on the 800 line and was told to call a repair man. The Parts select diagram helped me to identify the part I needed. It was clear enough that I was confident it was the right one. Three days and six screws later the machine was working fine.

Replaced rotor assembly by removing the back panel off the washer. Removed center bolt to be able to take out roto assembly. Magnets made it a little resistant, but with a little wiggling came off fairly easily.

new pump was a little different ,but mounted properly. Tipped washer on its side, changed pump by working trough bottom and back access. It went pretty smoothly, works fine.

Took off the old one and put the other one on. The only difficulty was that my husband has big hands and had a hard time getting to one end.

Disconnected power. Removed washer top; only 2 screws in back. Disconnected two wire connectors on Filter Assembly Circuit. Removed assembly; 1 screw. Installed new assembly, reconnected wires, and replaced washer top.

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.

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.

found the leak, went to the website, called customer service, ordered the part... $24 later, problem solved. Great customer service and on-line support

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

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

The drawer was knocked off the top of the washer and hit the floor. One of the two plastic strips in the back that fit into the channel to insert the drawer broke off. Super glue would not keep it together, so I ordered a new drawer. So glad this site had it...LG does not sell replacement parts, and I did not want to buy a new machine for such a minor problem!
