Frigidaire Dishwasher Pump Wont Stop

Hi, my dishwasher ejector pump wont stop running. The pump is working and draining dishwasher, it just wont stop running. I even removed the drain tube under the dishwasher just to make sure all the water was out. I also remove the spray arm and strainer screen and cleaned everything out in the sump. It still wont stop running. I see there is a sensor in the bottom of the sump, my best guess is the sensor is bad? Is that sensor what tells the pump to turn off when the water is out? Thanks!

I doubt it, more likely the control board is bad.
Draining is just a timed event.
Unless the turbidity sensor is doing something weird.

Have you tried removing power from the unit for a couple minutes to see if it will reset.
