WM4070HWA LG Washer - Instructions

Disconnect electric and remove top cover and remove connectors and hoses then the valves

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.

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.

took out the drain pump and replace with a new one

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.

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

Simply took hose off from inside machine and replaced it with new one. The tore one had a stopper on one end that wrapped to front machine; inside filter compartment. So I put stopper on the other end of new hose and wrapped it to it's holding spot in filter compartment.

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

1. Unplug washer. 2. Shut off water supply (hot and cold). 3.Remove hot water hose at washer inlet. 4. Remove the 2 plastic pieces that hold the washer top to the washer body by removing the 2 retaining screws. 5. Pull the top back to remove and set the washer top off to the side. 6. Unclip the electric harness from the inlet water valve. 7. With your pliers, loosen the clamp on the water inlet valve discharge hose and remove the hose from the valve. 8. Loosen and remove the 2 screws holding the inlet valve to the washer body. Install new hot water inlet valve and follow steps in reverse. Check for leaks before plugging washer back in. Run washer and check for leaks. Note: Excellent video available on You Tube. Consider replacing both the hot and cold water connecting hoses during the repair if they are old.

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.

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.

The problem ended up being the pump motor which discharges water from the washer. I figured out this was the problem after trying several things. I determined the motor was fine when it was empty. With the unit turned off, if you can rotate the tube with a quick spin and it lights up, probably this is OK. Then I tried to run it again and it went about 1/2 way through the cycle and stopped and started humming again. So I started emptying out the water, which I noticed was about 5 gallons which is way too much. so once empty, I took the pump off by turning unit on side. There are two hoses with hose clamps, and a few screws. Be careful to mark which wire plugs onto which side of the pump. One is brown and one is black. If you take the pump housing off, with the 3 screws, you should be able to pull the motor apart. Mine had water and scum from the wash in it, which was a dead give away that it was the problem.

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.

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