Product review (5 stars): Try fixing washing machine yourself if you get the LE code on  an LG washing machine
I have an LG WM1832CW washing machine. I got the LE error code. The machine would not agitate. I tried unplugging and resetting the machine. The machine would start filling but would keep giving me the LE error code.

I called my local service center and ordered this Hall sensor. The next day my part arrived. I picked up the Hall sensor and installed it following the video install instructions I found online.

Did it work? Yes!. Thanks to the internet our washing machine is up and running. I was ready to call the service center just in case. No need, just check and order this part for just under $20 if the LE code shows up on your LG machine.

Search for "dreaded LE error code for LG " and you will find video instructions.
