Bosch Dishwasher SHE68M05UC/50

Hi, Dishwasher shorted/has no power: The house supply line (hot/ black) wire came loose from the terminal block (L) at bottom of dishwasher and contacted the metal terminal box that the block is housed in. This did not trip house fuse breaker. Shut power and reconnected wiring. Unit was/is properly grounded. Voltage is present on line/hot (L)-black but also shows voltage at (N)neutral/common-white when connected to the terminal block. Not sure if that is normal??? When using the power button set to (I assume- OFF)- there is voltage present only in the 2 heavier gauge white and black wires going up to the power button in the main wire harness. When pressed again (I assume-ON) there is voltage present in every single wire except for green in the main wire harness going to all connections in the door. No lights from the top cycle selector buttons & LED(main control board AP4300440) nor the front face LED(PC board AP3908884). This machine also has a control unit board(AP4300389) on the lower right side and a capacitor(AP3857731) behind the terminal block. Trying to determine which part is the likely shorted culprit and if there are any fuses/switches that may have blown. Thanks for any help troubleshooting this, thanks! Howie CZ
