Michael for Model Number FDB4315LFC2 Display and control panel stopped working, got replacement main control board per recommendation, after replacement the display changed codes to "91" and the China wash light remains on but the dishwasher still does not work and none of the buttons work. Changing back to the original board, the display now only displays the "91" and china setting, the original error code is gone. A previous search for the issue showed the touchpad and control panel to potentially be the problem.
