I was receiving the F11 error and I replaced the MCU and it did not fix my problem. I went through and checked all the wires and when I went to pull the large wire harness from the motor all the black wires popped out. Luckily the wires stayed in the correct order so I re-spliced the wires hooked everything back together and the machine started working again.
The vibration had - over time - weakened the wires and the connection.
