WM4270HVA (01) LG Washer - Instructions

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.

Took off the old one and put the other one on. The only difficulty was that my husband has big hands and had a hard time getting to one end.

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.

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.

First I turned off the hot and cold water supply and removed the water lines from the back of the machine. I then unscrewed the 2 phillips head screws on the back of the washer for the cover. I slid the cover back and lifted it off the machine. Next, I unscrewed the mounting screws from each inlet valve assemble located on the back of the machine by the hose connections. I used pliers to pull the hose clamps back from the inlet valve, 1 at a time, then reconnected each hose and clamp on the new inlet valve. Once each hose was connected to the new inlet valve, I discarded the old inlet valves. I then re-attached each inlet valve. I placed the cover back on the machine and secured with the 2 screws, re-attached the water supply hoses to the hot and cold side and turned the hot and cold water supply back on. Everything successful, no leaks, and washing laundry again..........leak free!

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

After finding you on google it was easy to repair. It saved me $95.00 service charge. Your direction made it very easy.

The repair went well and your parts are easy to find. This is the second time I have used your services and both times have been great. Your parts are at great prices and your delivery is a lot faster that one would think.
Thank you

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

unplug washer and disconnect inlet and outlet hoses. drain water from washer (about 2 gallons) by removing lint screen from front of washer. lay washer on side (I used a blanket to avoid damaging the paint) remove all the phillips head screws in the plastic bottom and the metal feet of the washer. Gently pull the bottom of the washer off. There are 3 shock absorber looking things that pull apart and are greasy. Try not to mess with them much. Just pull gently, and they slide apart. cut the zip ties holding the wires to the washer bottom piece. remove the screw in the lint screen area and gently pull the recessed plastic thing out the front of the washer. remove the screws holding the pump assembly on the front of the washer. Remove the three screws holding the pump assembly on the outlet pipe manifold. Installation is the reverse of removal, take care to put the shock absorber looking things back in gently and together at the same time when reinstalling the plastic bottom of the washer.

I ran the spin & drain cycle to empty the drum,I waited to be see how long it took to see a noticeable level of water in the drum (1-2hrs).decided to check the cold water valve first.Found that there was rust forming around the solnoid piston,making it hang up,most of the time it tryed to open, or close. cleaned with light sand paper(piston), and ordered part with parts select. Which was real easy,because of the knowledgeable staff,parts came in as promised,and in good shape,and most important of all it was the exact replacement part. My wife is HAPPY,which makes my life good too! THANKS Parts select..

I took the back panel off the washer and located where the leak was coming from. It was obviously coming from around where the cold water hose connects. Checked washers in hoses and they were good. Noticed a small drip on the valve assembly that the hose connects too. Took off small panel where the hose connections are mounted....disconnected all 3 black water hoses that connect to it (squeeze metal clamps with pliers and slide hoses off. and numbered them with permanent marker so I wouldn't get my lines crossed later), removed the quick disconnect electrical lines.... removed part and googled the parts diagram on this site.....identified the part in the pic and ordered....it was here in less than 48 hrs with the basic shipping (which stated 3-5 days:)....reassembled the same way I took it apart. I'm prud of myself, it was pretty easy and I'm sure it saved me a lot of money!:)l

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.

Basic skill
