WM0642HS LG Washer - Instructions

took out the drain pump and replace with a new one

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

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.

Disconnected power. Removed washer top; only 2 screws in back. Disconnected two wire connectors on Filter Assembly Circuit. Removed assembly; 1 screw. Installed new assembly, reconnected wires, and replaced washer top.

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.

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.

Unplug washer!!! 1. Remove retaining ring around rubber gasket with flat head screwdriver. Just slightly pry off and it will easily come off. 2. Just peel back rubber gasket on the side that the lock is on. 3. remove 2 screws from the front off the lock assembly. 4. gently reach in and lift the little plastic clip holding the wiring harness and lift straight off. If the clip is lifted it might be a little tight just use even steady pressure to pull off. 5. Reverse these instructions to replace. Note: replacing the retaining ring on the rubber is a pain. The spring has to be in the bottom. Using a couple of flathead screwdrivers you can wrangle it back in place after awhile. There is a tool that looks like a large reverse pliers that may make it easier. Anyway thats it, pretty easy. There is a youtube video that shows all of this.

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.

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

The bellows hose on the bottom of the tube had worn through where it flexed. This was an easy job except for the long reach you had to make under the washer to reach the hose clamps that held the part in place. These were spring loaded clamps which were easy to remove with pliers. I replaced them with ones that could be tightened with a socket wrench since it was hard to replace the sprung clamps.

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.

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.

Conclusion was that either the control panel or the noise filter (an electrical fuse apparatus)was bad. Disconnected the water line, turned off power, and pulled unit out from cabinets. Determined that voltage was going into the noise filter (white harness) but almost no voltage coming out (red harness). Ordered noise filter. Hardest part was removing old noise filter from dishwasher frame without removing the whole unit from cabinet and turning upside down.One screw holds the part in the frame. With power off, I used a very small ratchet with phillips screw driver. Pried unit out with screw driver on side to the panel front. It has a retaining tab there.Installation was the reverse. Instead of putting screw back the way it was originally installed, I screwed it in from the outside of the frame. Much easier and just as solid. Tested unit with power on. Hooked up water line. Works great. Note: LG dishwahers have a high repair rate and that this part has a high failure rate. This LG unit was two years old. Never had to fix my 15 year old Sears dishwasher. It still works to this day. (I gave it to my daughter.)

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.
