Bosch dishwasher wont start

No power on the front buttons, breaker ok… What next ?

Remove the toe panel and check the wires at the dishwasher junction box. Test the door switch, the "on-off" switch and all other electrical components according to the wiring diagram.

Need to replace the Part Number: AP4396792. However, the one I have has four wire terminals and the shown part has five? How do I know which wire to place on which connector. Mine are labeled:

"BA" "L1" "BR" "N"
