WM3431HW (WM3431HW /00) LG Washer - Instructions

It was giving me a code got on YouTube it gave the code after that bought a new pump and fix done

You have to take the back plate off the machine.The hose is all the way up front on the bottom right hand side.It has a spring clamp on it.You have to turn the hose to reach the clamp.After that the job isn't that bad.

Replaced cold water inlet. Removed 4 water lines and 5 wires put new part in and reinstalled lines and wires

After I watched the repair video for the part, it was a snap. It went exactly as the video described the steps. Hardest part was moving the washer to get behind it.

To fix the problem, I simply removed the top cover of the washing machine by removing the two screws on the back of the machine which allowed me to slide the top back and then I lifted it off. Then I disconnected the hot water hose (after shutting off the valve). Next, I removed the electrical connectors on the old part as well as the hose attached to it and unscrewed the old part and removed it and put the new one on and reattached the hoses and the electrical. It worked like a charm. It took me perhaps 10 minutes total.

It went great. First of all, thank you Part Select for the video on how to do this myself. My home warranty company was giving me a hard time. Blah, blah, blah. A mechanic friend of mine referred me to this site. Within minutes I found the part I need and a GREAT!!!! price. Ordered it, got it super fast, fixed it my self and my second hand washer is no longer peeing all over the floor. Very very happy. I will definitely be a repeat customer, hopefully not anytime soon.
Thank you again for an amazing experience.

I took the washer completely apart and ordered any parts that looked worn and put it back together. It’s working like new and will last for a few years

Followed the video instructions provided.

Change the thermistor

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.

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.

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.

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.)

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.

My washer would try to spin and remove the water according to the time allowed. Consequently my washer would take longer than the time allowed to drain therefore water would send a code error then the machine would stop working. So I remove the hose from the pump and found my son's little small sock blocking the drain. I removed the sock and reinstalled all hoses. Everything is fine now. No need for a replacement item. Just a little servicing.
