WM4070HWA LG Washer - Instructions

The repairs went great thanks to the videos and Steve.

First unplug the machine. Turn the water off to the hoses. Remove the hoses from the machine to make it easier. Remove the screws from the back of the top cover. Pry the front sides with a screwdriver and lift. Standing behind the machine on the left side you’ll see the three solenoids or inlet assembly. Remove the two screws so as to take the inlet assembly out. There are hoses attached to the assembly.

Removed top panal found broken parts and pieces, replaced spring and plastic spring holder. Straightened out and reattached drum front boot.

Simply inserted new plunger/magnet back into door with thumb&finger until you hear the little locking tabs click. No tools required.

Disconnect washer - pull out and turn on it's right side. Remove bottom plate (2 screws). Water intake valve is attached to water line. Disconnect water line. On the other end of the pump is a rubber hose. Disconnect hose by using a pair of pliers to open pipe clamp. Disconnect the electric line by pulling the pronged plug out of the pump. The part is composed of the pump and a metal mounting plate. They are connected by 4 screws. Remove the screws and pull out the back half of the pump. The front of the pump is attached to the washer frame by 2 screws. When removed you will notice an o-ring that forms the seal between the two halves. Remember this when installing the new pump. You will have to take the new pump apart because the whole part will not fit through the frame opening, thus the need to make sure the o-ring is properly seated. You can either install the mounting plate to the frame then attach the pump half or with half of the part in front of the frame and the other half behind the frame connect the two, then attach it to the frame. Reconnect incoming water line using teflon tape and a crescent wrench. Reconnect out-flow line with the pipe clamp and attach the power line. Since you have to take the new pump apart make sure the o-ring is properly seated as it will have a tendency to fall out. Reassemble the rest.

Took front of machine off to access 2 shocks, put back together then removed panel in back to access third shock, watched YouTube video first so things went smooth

you tube it , not to hard to install

Disassembled washer, replaced bearings, seals and gasket. Watched instructional video to familiarize myself with the repair. Followed all steps as recommended, repair was straight forward without any surprises. Hardest part was removing the drum from the machine, somewhat heavy. Disassembled and replaced all bearings, seals, spider and gasket. Reinstalled in reverse order. Note: Upon tear down, I found the seal was pushed out, causing the bearing failure. I also found that the seal was installed incorrectly from LG. They have the seal lip facing the bearings, should be facing the water. This repair seems to be difficult, but was fairly self explanatory. All plug ins are color coded, all hoses are accessible with little effort. If you have basic skills you should be able to handle this repair.

I youtube searched this problem and found a video from partselect. I watched the video, purchased the part, and followed the video instruction step by step to repair the washer. Part with tax and shipping was $52.

2 hose clamps and a hose, easy! This would be a very common cause of leaks in washers due to all the movement inside.

I ordered the Rotor Assembly and Sensor Assy..
Rotor Assy. was not the problem.
1 - 17mm bolt in the center of the rotor assy.
6 10mm bolts to take off the Stator assy.
once you have the Stator assy off, upplug the sensor assy and release the clips on the sensor assy. and remove.
Install the new sensor assy. and plug the electrical connection back in.
replace the 6 bolts and screw the bolts evenly around the Stator.
replace the Rotor Assy. and secure the 17mm bolt.
Replace the back cover (4 - philips screws.
Do a test load.

YouTube is your friend for many such repairs. See this link for an overall description:

I had to remove the top panel to determine exactly which valve was leaking. It turned out both hot and cold-water valves were defective.

After unit is unplugged and top is removed, it's a simple matter to remove/replace hose connections and electrical connections. It took me less than an hour to complete the task once parts were in hand.

Again, YouTube is your friend for such repairs.

Do not start this project without the required spring expansion tool for the retaining ring springs.
Nearly impossible without it.

Unplug and disconnect water lines. Move washer out. I used soapy water to make it easier to slide because it is stacked washer and dryer. Slid dryer onto large trash can saving my back. So easy. Make sure it is heavy duty . Removed lid. Removed old part by removing to screws in back. Disconnected 3 wires, disconnected one hose at a time while reattaching each one to new part. That way I was sure to get them back in the right place. Attached back to machine . Put water hoses back on and checked for leaks before but lid and dryer back in place. Ta da!! This was so easy. I am a 57 year old woman and this was pretty simple. I tried trouble shooting by using tub cleaner and everything as manual suggested but it still leaked. Watch a lot of you tube. Apparently lg has this happen with this part a lot. Thank you parts select. I’m sure this saved me a lot of money. I have had enough money bleeding from my pockets with bigger home problems. Thank you.
