WM3431HW01 LG Washer - Instructions

Not too bad, had a neighbor help with the project as washer/dryer were stacked. removed dryer from on top out of way. Drained washer, tilted on side to get access from down below. Second person help here. unscrewed drain pump from front, Used pliers to unclamp hoses, disconnect wires to motor (already pulled power from wall) pushed plastic clip holding in unit and pulled out. New unit was factory new, not a knockoff. We took extra time to clean out hoses, especially from the main washer unit, it was a simple unscrew clamp and pull hose down. We sprayed out gunk from hoses and parts going back in. Once new unit was ready, installed back and reconnected hose and power. The clamps were somewhat of a pain with the overall size and angles to get them seated and on correctly. Much easier to take off, but take the time to reinstall correctly. Don’t need water leaking. Motor much quieter now, wife is happy.

you tube it , not to hard to install

Watch the video to repair and follow along

Turn off circuit breaker. Turn off water at shutoff valve usually located under sink. Disconnect water line from dishwasher. Disconnect wires for the power feed from cord, Marked corresponding wires upon removal for re-installation. Remove 2 mounting screws that secure dishwasher to counter. Slide dishwasher out from counter and turn upside down. Use a blanket to prevent scratching of surfaces. Locate component on the back portion of the dishwasher. Unplug 2 wiring harnesses. My part was held on by 2 phillip screws. One in front, the other in the back along the leg bracket support. Once removed, reverse the order of removal. The i a You Tube video you can locate fr this removal. They said that you needed to release a clip to get the part out. Mine had a screw holding it on the back side. This difference cause about an extra 1/2 hour before I was able to figure out that there was NO clip that was being shown on the video. After that, The replacement went smoothly and we were having the dishes washed later that day.

Totally dis-assembled this washer to check the bearings and drum plus fix the pump problem. We wash dog blankets occasionally and found the little drain hose from the front door gasket was clogged with hair. It makes a 90 degree turn and it gets caught there. THAT fixed the smell issue. As far as the pump replacement goes its quite easy. Videos online are your friend.

Follow the LG washer video.

followed instructions on video , when part was delivered I had washer fixed in about 1/2 hour, very easy to fix . Wife is happy and I saved a lot of money. Thank you partselect.com

Do not pay a service company to come to your house to make this fix!!! If you have common sense, simple tools, a phone camera and some mini zip ties you can do this!

After watching a couple YouTube videos on installing a new motor I had the confidence to start the job. My biggest worry was I'd forget where a screw/part went so I took a lot of pictures as I disassembled. I also laid all the parts out on a table reflective of where they belonged on the machine. I learned washers aren't rocket science - YOU CAN DO THIS. The most difficult part of the fix was my washer was a different model so much of the caging was completely different than YouTube disassembly, but once I got into the machine it was fairly identical. Easily popped out the old, broken motor and inserted the new LG certified part. Reassembled in 1/2 the time of disassembly and my machine works like new:) Hoping to get another 10+ years out of this washer.

Thanks PartsSelect for the high quality certified LG part. Very nice quality and weight.

Used Youtube to look for a set of repair instructions. From start to end 35 min.

The difficult part was getting the door back on. Only 1 Youtube video I watched stated Do not remove the 2 center screws at the top. Wish I had seen that video first.

Overall very easy to do.

1 tilt washer back
2 remove cover plate screw from front of drain filter access panel.
3 Remove cover plate and remove 2 more mounting screws .
4 go below washer and pull down sliding clip and move pump assembly back.
5 remove wires and 3 mounting screws around pump housing
6 Swap pump and re-attch wires

I followed the video. Everything worked exactly as described. i ran a quick cycle and everything seemed to be fine. Started a wash and the machine was going fine but stopped, and wouldn't drain. I thought that maybe it might be the Rotor Position Sensor assembly, which I had already purchased just in case.But first i drained the machine and checked out the pump filter. Plugged solid. I'm guessing when the pump went there must have been a lot of lint and debris in the machine. something you might want to check out, after that repair. Thanks. you guys saved me a couple of hundred dollars

Remove where the water pumps are and remove the one that was damaged easily

Slide out double stack unit, take the back off, stand on my head and reach in to remove hose clamo off pump hose. slide new hose on and clamp, but back on, and slide washer/dryer stack back in to place.

When to utube typed in my problem, very easy fix

I followed the video and it was quite simple. There was an extra sheet metal screw at the bottom of the front panel which kept it from coming free of the three tabs. On the two pump wite connectors I made a mental note that the black wires were on top. The repair also fixed the lack of water flow through the degeterent dispenser. I was afraid of putting the tub seal back in place as a pro struggled with it when it was new and under warranty. It really was no problem at all. Take some phone pics along the way boosted my confidence.
