Hi did you resolve this? I have a similar fault and do not know if it is the sensor or not.

sensor is in the front door.if it has moved out of alignment with the spray arm this could be your problem.it is a reed switch and counts the pulses as the arm on the top basket rotates.too few a counts generates an alarm code.odvious thing is to make sure the spray arms rotate when the pump kicks in.
