WM3170CW LG Washer - Instructions

We drained the water from the washer via the tiny hose/filter located at the lower left corner of the washing machine. The unit was then pulled away from the wall, unplugged and the hoses disconnected. At this time, we used the wet dry vacuum to suction the water that remained in the drain hose. We tilted the washing machine back until the front of the unit was 18 inches or so off the floor. We used the foot stool to hold the washer up in the air so that we could work on the pump. Replacing the pump was as easy as removing a few screws, unplugging the electrical connections and removing the faulty pump assembly from the plastic housing. (Be sure to mark what connector goes in what terminal). Re-assemble. Re-connect. You are ready to go. It took more time to ready the washer than it did to replace the part.

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.

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

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.

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.

found a slow leak in one of the valve seat gaskets and decided to replace the entire valve (also did the hot inlet as well just in case). Unplugged unit, detached water hoses (replaced these as well), moved the washer out about 12" from the wall. With Phillips head removed the washer top. With pliers removed the hose clamps off the valve heading to the detergent dispenser (be sure to keep track of what hose goes to what nipple). Detached electric clip from each solenoid. Using Phillips head removed the valve. Use reverse order to install new valve. Ran the unit through a long cycle with the top off to ensure there were no leaks.

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!

took out the drain pump and replace with a new one

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 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.

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. :(

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.

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.

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.
