I have 2004 LG WM2177HW front load washing machine. I wish it had the plastic lifters you showed, but it doesn't. There are no visible screws on the lifters in this model. In your video of disassembling a Duet front loader, it has the same plastic lifters as my front loader.
I see what happened, the model changed on me when I entered it into the look up. Either way, there is a screw coming in from the backside of the lifters. You must completely uninstall the outer tub of the basket and split it open in order to access the screw coming in from the back of the lifters. Then the lifter will pull forward and off. It's a lot of work to remove these lifters.
So your diagram show there are screws under and behind the lifters? I was hoping the screw under the lifter ( which is not connected directly to the tub) could release the top part of the lifter...Does your diagram show what that screw under and inside the lifter releases?
It does not. but it does hold the top part of the lifter in place, but there are more things toward the back coming from the outside of the basket of the lifter that you'd also need to release in order to pull the top part of the lifter off.
Thank for double checking! You saved me time and frustration!
