Dishwasher wont drain. Checked motor its good, checked for blockage and its good. I think control board bad. I read that I can bypass on board but cant remember or find page.
You would not be able to bypass the drain on the control board. You could start the unit and see if there is power at the control board to the pump when the unit calls for a drain cycle. There should be 120 vac at the board. If there is power from the control board to the pump then check the pump to make sure that it is getting 120 vac. If not then you will have a wiring issue. If there is power but the unit is not draining then the pump would be the issue.
