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.

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.

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.

1. Remove spring-loaded clamp assembly. 2. Partially pull out the large rubber gasket near the lock switch assembly to gain access to the lock switch assembly. 3. Unscrew two screws holding the lock switch assembly. Carefully separate the connector from the lock screw assembly and replace it with the new part. Reinstall in reverse sequence. Ensure that the electrical connector is fully seated unto the lock switch assembly and the connector latch is fully set against the lock switch body. Also make sure that the large rubber seal is fully seated around the door opening to prevent water leak. Restarted the washer and everything worked as before.

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.

pulled off top of washer to get at the inlet valve disconnect two hoses take two screws out and then you put it back together the way you took apart and your done

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

Replaced rotor assembly by removing the back panel off the washer. Removed center bolt to be able to take out roto assembly. Magnets made it a little resistant, but with a little wiggling came off fairly easily.

new pump was a little different ,but mounted properly. Tipped washer on its side, changed pump by working trough bottom and back access. It went pretty smoothly, works fine.

Removed the old bellows (2 squeeze hose clamps and one screw adjustable hose clamp) slid on the new one and it was done!

Unplug Washing machine first. Then remove 2 screws at the back of the top cover. Slide the top cover back then lift and remove. Unplug electrical connector @ inlet valve and remove water lines 1 going in and 1 out of valve. Remove 2 screws holding assembly in place then install new valve assembly and all other components in reverse order.

removed top, removed 2 screws, replace part. did not fix problem, the real problem was the water inlet valve, works great, easy fix. thanks

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.
