Samsung Dishwasher Drains, fills & Drains Again

Hello subject matter experts
I have a Samsung Dishwasher DMT400RHS and our dishwasher stopped working the other day. When I turn in on to run, it drains, fills and then immediately drains. Both the Heavy and Smart Auto lights start to flash and dishwasher still tries to drain without any water in it.

Any idea what could be the issue here?

bowdeC01 did you find the problem, mine started to do the same thing yesterday and All I could find was "Possible defect : Sub PBA in control panel, Main PBA" — WHAT THE IS A PBA… Sorry just got off of the phone with Samsung and all they could say is its a Internal error??? Really I thought it was something in my back yard. Is it the control board or the control panel (keypad). I’m pretty sure I’m done with Samsung appliances. Thank you.
