WM3431H LG - Instructions

Change the thermistor

Followed the video instructions provided.

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.

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.

I watched a video of how to replace the pump and it showed taking the top and front off to get to it. I actually found this could be done by removing the back panel from the washer. There were two hose clamps you have to squeeze and slide up and two wires going to the pump. There are three screws holding the pump that need to be removed from the front of the washer. Once these are removed all you have to do is push a tab down and the motor slide right out. The pump assembly can also be reached from the bottom of the washer.

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.

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.

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.

Turn off hot water supply and activate a cycle on the washer momentarily, with hot water selected on front panel options to relieve hose pressure. Slide washer out to gain access to rear of unit. Unplug washer from AC source. Using pliers, remove washer supply hose from washer-side of the line (water may drain from hose) Remove single Phillips screw at bottom of each nylon lid holder at rear. Using a plastic putty knife, place between front panel and top lid to loosen lid and slide to rear. Remove lid and store aside. Hot and cold inlet valves sit side-by-side at top rear of the unit. Disconnect connector from valve by pulling gently away from valve plug prongs and place to the side. Using pliers, compress hose clamp and move to lower section of hose. Carefully rotate hose back and forth to remove from assembly. Inlet valve is held to washer body rear with 3 small Phillips screws. Remove first 2 and then while holding inlet valve body, remove final screw to free inlet valve assembly. Replace with new assembly by reversing these steps.Make certain when supply hose is reconnected, it is firmly tightened but DO NOT over tighten. Test washer by running a cycle to ensure there are no leaks.

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.

took out the drain pump and replace with a new one

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

This was very easy to instal. The aplaiance repair co. wanted $240 my LG is six years old and would rather buy a new one if I had to spend that much, so I gave it a shot and it took me 20 min to install the part. Told my wife she owed me $ 180 for my labor.

Removed screws from door, not hinge, replaced handle, reinstall screws and you're done!
