You have a bad thermal fuse, or damaged wires.
Here you go.
A) The black wire to the fuse, is a direct connection back to the junction box on the frame of the dishwasher base. ( it's OK)
B) The P2pin#6 wire at the control board, is attached to the outlet side of the thermal fuse, no voltage indicates a bad thermal fuse or wiring problem from the thermal fuse to the control board.
C) The P8 connector on the control board, is power into the control from the door switch and the thermal fuse, no voltage indicates a wiring issue, or bad door switch and or thermal fuse.
You may want to bypass the new thermal fuse, to test the dishwasher operation and wiring, but don't leave it in that condition. and then order the fuse again.
