WM3431H LG - Instructions

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.

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.

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.

Removed lid (top of washer), then ran a cycle in normal to identify the failed component, then noticed the water inlet valve assembly for the hot water was leaking, used my pc and went to website Part Select and found to failed part on the parts break down item, then ordered the part, the part "Valve Assembly Inlet" for the hot water arrived 2-days later, replaced valve in less than 5-minutes, disconnected push on electrical connector, unscrewed the valve assembly inlet and installed the new valve assembly inlet, very easy

I received the part needed within a few days from ordering. I immediately removed the leaking part with the new part. It was a very simple install, and my washer is now leak free. If you think you cannot do these simple changes, think again, it's much easier then you may think. Remove the top cover of your washer machine by taking off the two screws in the back. Remove the hose clamp with a pair of pliers and pull off from the intake valve, of course make sure your water valve is shut off before starting. Remove the two prong clip. Using your pliers, disconnect the main hot water hose. Use a Phillips screwdriver to remove the two screws that holds the valve in place. Remove and discard it and replace with the new valve. Follow the steps and your done, it's that easy....TC

Followed the instructions that a fellow DIYer posted in PartSelect and a few I watched on Youtube. Pull out the detergent drawer, remove the back screws, slide the top off, unclip the control board, unplug Power & One more switch so that I could move it aside. Take the gasket retention wire off the door gasket & tuck it inside. Remove the screws in the bottom & top. Then slide the front panel, including the door up (not easy) and out. The part received was only the pump motor so I had to take a few pictures before so I knew I got it together right. Remove drain houses, pump screws, slide pump back and remove pump. A few more screws to remove the pump from the housing & replace with new pump. Put it all back together. It works! It only took about 45 minutes

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.

Tipped the washer on its side to expose the bottom, removed the plastic lid adjacent to the pump after removing the screws holding it , then, using a flat head on a pry tab pulled out the pump, removed the hoses with pliers to complete the extraction, swapped the pump on my bench. . assembly is reverse of disassembly. .

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.

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