WM3997HWA LG Washer Dryer Combo - Instructions

Unplug the washer! Turn off the HOT water valve. Remove the hot water hose at the connection on the back of the washer. Remove the two Phillips head screws holding the top of the washer. Slide the lid toward the rear until you feel it disengage, then lift it off, setting it aside.
Unplug the electrical connector on top of the hot water valve (just pulls off).using pliers compress the hose clamp, slide it away from the hot water valve and pull the hose off the valve fitting(it will have some water remaining so lift it up and secure it to the brace above the hoses).
Remove the two phillips head screws that hold the valve in place. Pull the valve toward the front of the washer to remove it and compare it to the new valve.
To install the new valve, reverse all steps insuring tight water hose clamp and electrical connection. Install hot water hose, plug it in and turn on water. Test run and check for leaks. Unplug it and reinstall top.

From my research, I thought I needed to replace the Hall Sensor (also known as the Rotor Positioning Sensor). The Part Select site informed me that I might need to also replace the Rotor Assembly. The site said that I could not order just the Hall Sensor - I needed to order the Washer Motor Stator which would include the Hall Sensor. When I received the order, I found that the Motor Stator did not include the Hall Sensor. I found that I could order a part that matched the Hall Sensor I removed from my machine. I then ordered that part. I installed just the new Hall Sensor - the machine worked. I have returned the unused parts.

Watched instructional video. Made it easy

I followed the video -- to take apart and reversed the steps to re-install. It was fairly straight forward and corrected the issue.

E. Z. hardest part (which isn't hard) was moving the appliance to reach the back, then putting the appliance back into place. the actual repair (swapping out valve) took less time than that to do.

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

Use just your finger to push it into place. VERY EASY

Honestly youtube but pretty simple install.

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

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.

Totally dis-assembled this washer to check the bearings and drum plus fix the pump problem. We wash dog blankets occasionally and found the little drain hose from the front door gasket was clogged with hair. It makes a 90 degree turn and it gets caught there. THAT fixed the smell issue. As far as the pump replacement goes its quite easy. Videos online are your friend.

Not too bad, had a neighbor help with the project as washer/dryer were stacked. removed dryer from on top out of way. Drained washer, tilted on side to get access from down below. Second person help here. unscrewed drain pump from front, Used pliers to unclamp hoses, disconnect wires to motor (already pulled power from wall) pushed plastic clip holding in unit and pulled out. New unit was factory new, not a knockoff. We took extra time to clean out hoses, especially from the main washer unit, it was a simple unscrew clamp and pull hose down. We sprayed out gunk from hoses and parts going back in. Once new unit was ready, installed back and reconnected hose and power. The clamps were somewhat of a pain with the overall size and angles to get them seated and on correctly. Much easier to take off, but take the time to reinstall correctly. Don’t need water leaking. Motor much quieter now, wife is happy.

you tube it , not to hard to install

Watch the video to repair and follow along

removed top and front. heater is at the base of the tub. the nut compresses the rubber seal and may take some wiggling to remove the old one.
