After a few minutes, the dishwasher displays an OE error on the display. The filter is clean and the drain line is open. I replaced the pump motor and the OE still displays. How do I verify it is a PCB control board and how do I know what control board to purchase.
With having already replace the drain pump which did not correct the issue, then you will want to check the wiring of the unit to ensure there are no damaged wires between the pump and the control board and if the wiring checks ok then the issue would most likely be the control board EBR63265303.
