You will probably need to remove the top cover and possible the back service panel to find the source of that leak. I provided a procedure for removing the top cover of the washer in the image below. You can remove the screws in the back panel to remove that cover as well. Be sure that you
unplug the washer
before accessing internal components. With those covers removed, you may be able to find the source of your leak.
You can view a parts diagram and order parts from this page:
LG Washer Model WM230 . . . Parts
. Use the full model number of your washer to access parts diagram for your exact model.
If you can find the source of the leak, you may be able to fix it yourself. If you need more assistance, reply with additional details.
If you get to the point where you need to have a service technician examine and repair the washer, you can schedule service through this link:
