I have an LG WM1812CW front loading washer and in the middle of a cycle it will completly cut off and the LED panel goes black. Total loss of power. You have to start the cycle over and sometimes it will make it all the way through and most of the time it will die again. I posted a my problem on this web site and someone answered and told me what part they thought might fix the problem. I recieved the part but I still have the problem. The part I got was 6871EC2041A PCB Assembly, Display. It is just the part behind the buttons on the front. There is a main board that is behind the control assembly that has lots of electronic parts and many wires plug into this board. If I'm guessing this is the main board and most likely my problem. But I'm not an expert and looking for some advice. Any ideas?
