WM3431H LG - Instructions

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.

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.

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.

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

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.

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

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.

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.

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.)

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

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.

Basic skill

Found great Youtube video, followed step by step. Only difficult part was getting the tub gasket clamp back on. But all in all pretty easy. If tub won't drain and weird noise coming from pump do not hesitate to do it yourself and save some coin!

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.
