Two part question:

1. This is machine is sold in Costa Rica and I believe it is made in MX. I read here that the model # can be converted to an American #. Can someone please tell me how to do that? I have been searching for parts for this model and it is as if it doesn't exist. Even LG has ignored my requests.
2. The first problem with the machine began with the knob. I was unable to use it to switch wash modes. It worked for about a year on the standard available cycle. Now the machine just shows 2 dashes on the digital display. Upon opening I see that there seems to be burn marks on the control board behind the knob. I want to begin by replacing that circuit board. Can anyone tell me what is the exact name for that part and which # on the board I need to reference to find a compatible replacement part? It seems as though my only option is an aftermarket part, since LG is unresponsive. Any advice greatly appreciated. 

The cover on the back reads:  INSULATOR PCB MEV47160301 >ABS< SW 18.11 2-2

I also have clearer photos of the visible numbers and print on the board.

Thanks!
