Ok, well I guess nobody wanted to chime in on this one. Since the turbidity light was on at the lower board, I replaced it. After replacing it, everything worked and all the controls were able to operate fine. I just wanted to post this so that in the future someone might be able to find this useful. It is pretty neat that the light comes on at the lower board to tell you what is wrong.
Hopefully this helps someone in the future.
