I have a WFXD8400UC/01 Siemens washer. There is nothing on the display and it acts like its not plugged in. I suspect its the main board - 436437 - but, I suspect there is another board that may provide power to this main board? A parts breakdown shows a 436461 with no discripting. Is this the power supply? How can I check to see if the main boad (436437) is getting power? Does it use 120VAC or what?
