OK, so if the dish washer just stops after filling and the light is still on, you either have a bad circulation pump or a bad control board. You'd need to uninstall the dishwasher, remove the right side panel, start a cycle and wait until after it fills to test power going to the circulation pump through the right side of the dishwasher. If you're not getting 120 volts down to the pump, then you need a new control board. If you are getting 120 volts, then you'd need a new control board---by far the most likely culprit will be the circulation pump.
On the other possibility, if the dishwasher just drains and doesn't even fill up with water--then the drain pump is drawing too much power causing the clean light to appear and the drain pump would need to be removed to see if anything is hitting the drain impeller on the pump and if not then replace the drain pump even if it's draining fine.
