LG WM2688 Washer Main Control Board [6871ER1062D] 4.7 Ohm 5 Watt resistor opens and fuse blown [Cause ????]

[EMBergmann]

Trying to locate/download the schematic wiring diagrams for the LG WM2688 Main Control Board [6871ER1062D]. , I am in the :dark: here and need to have a clear understanding of what caused my MCB to fail. Searching for a resolution and understanding the nature of a particular part: 4.7 Ohm 5 Watt resistor and fuse on the MCB PCB as it has been widely written about. No one has described as to why it happens or even possible causes.  Thank you in advance for reading my narrative. Edward M Bergmann
