This is the Main Printed Board Assembly, part #: DD81-02638A, for a Samsung dishwasher, model DW80N3030US/AA-00.
If you are better at repairing dishwashers than I was, my colossal failure at correctly diagnosing why my dishwasher quit working could be your gain. I spent $255.56 for the new PBA from partsdr. com, but after removing the old PBA and installing the new PBA, the problem persisted; thus, indicating that there was nothing wrong with the old PBA. The photo shows the new PBA back in its original packaging and the old (probably still good) PBA (you get both) removed from my old dishwasher, which is now headed for the junk yard.
