How can we conclusively determine that the control panel has gone out or if the washing machine has a fuse out? At this time, we have power to the washer but nothing shows on the display.
There is a fuse in line of the power supply to the control board. You would want to test the fuse for continuity and if there is no continuity then it is bad. You could also test on the control board itself for 120 vac from connector 5 to connector 4 pin 1. If there is voltage here then replace the control board.
