WM4270HVA (01) LG Washer - Instructions

Ordered a new water valve, easy installation, removed top cover of washer. Two screws and three hose clamps, done in 20 minutes.

removed 2 screws on back. removed top. disconected wires and hoses removes 2 screws holding assy in place and removed assy. put in new assy and installed hoses and plugs in same location removed from. reinstalled top and hose and ran washer.. new valve unite works but has a high pitched whine when valves turn on. :(

I unplugged the washer, and removed the top of the washer by removing the two screws securing the top to the washer. You'll find them inside the two plastic pieces on the rear of the top. Remove only the bottom two screws in each plastic piece and slide the lid to the rear a few inches then lift straight up to remove the lid. Disconnect the water hose from the rear of the inlet valve assembly then remove the two screws in the rear of the old water valve bracket that attach it to the washer. Pull the old unit inside the washer and set the new unit on top of the old. Swap over the electrical connections to the new water valve assembly, matching the locations where the connectors were originally. Then swapped over the water lines from the old unit to the new unit using common pliers to compress the hose claps. Finally, attach the new unit to the washer with the two rear screws. Replace the water hose and the top, and the unit is ready to test.

The difficult part was finding the leak since it was very small and the washer was completely wet around the frame at the bottom. After completely drying everything off and waiting an hour-nothing.I had assumed the leak was in the bottom area around the hoses when actually the leak was the cold water valve[top rear] seeping,then dripping on the drum and dripping onto the frame 8 inches away.I ordered the valve about 10:30am online, the next day at 1pm it arrived. Very easy to install in 15 minutes.

Hot water valve was leaking when washer was not in use and flooded floor. Advised owner to replace hit and cold water valve same time since only hot valve was bad. Hot water was easy but cold was difficult because it has the bleach and softener valve attached in one unto with three hoses and three wire connections. The opening at back of machine was small and you must have small hands to replace them. If not, then you have to remove top cover to get to it which is extensive.

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.

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.

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

Did the repair entirely from the back.- 4 screws back cover comes off. Once you see the Bellows it is obvious what needs to come off and there are other videos on the net showing this. The main things I did differently were 1) Leaned the washer forward and placed 3 2x4 blocks of wood under each back leg. This allowed me to reach under the washer with one hand, and through the back with the other. You need both hands in there ! 2) Uninstalling is easy with just pliers. But on the way back in, I used a pair of Locking Pliers to keep the circular clamp squeezed as much as possible. That seemed the only way to get the bellows back in. Another option would be to switch to screw on Pipe clamps instead of the spring clamps.

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

First, slide top cover back, then lift of washer. Remember to turn off water supply and disconnect cold water hose before working on valve. Also, unplug washer from wall socket. Disconnect three small electric plugs from valve, noting the postion on valve,then disconnect the water hoses from valve, noting postition of each hose. Remove two small screws holding valve to washer,remove and replace valve.reistall valve, reconnect hoses and electric connectors. Reconnect water supply, turn on water supply, check for leak, reconnect power cord to wall socket. Run washer through normal wash cycle, observing water valve for leaks, normal operation, if no problems, then reinstall top on washer

The pump is apparently used for more than one washer, and the R&R instructions may be significantly different. I found a youtube video for my exact washer.

Removed the top, the front, got to the pump, removed it and replace it with the new one.

Found the part of Part Select by describing the problem. used a Utube video and step by step we were able to take apart, replace and put back everything with just a screw driver - I saved so much money!

Found on line OE meant washer not pumping out water with the suggestion to clean the filter and inspect the pump and lines for blockage. No problems there. You must be careful to empty the water manually before removing the filter. My wet vac helped but I still made a mess. I found a mechanic to look at the washer. He said it is common for the pump on these washers to go bad, especially if the washer has sat out of service. They wanted $300 to replace the pump. I found the part on this website for $53 and replaced it myself. The only hard part was emptying the water without making a mess and leaning the washer up and back far enough safely to remove the pump, then working on my back under the machine.
