I am getting an error 7E for Samsung dishwasher. I already replaced sensor and motor vane and unfortunately I am still getting the error. From the online research the only other thing that could cause 7E error is PCB. Hopefully this will fix the problem otherwise I am throwing it into the trash. Any idea where PCB is located in this dishwasher?
