How to Replace the Turbidity Sensor in a GE Dishwasher

The turbidity sensor in the sump pump assembly of a General Electric dishwasher measures the amount of suspended particles in the wash water and helps ensure the debris doesn't cause your dishwasher to clog or not clean properly. If washed dishes continue to have food on them or if food particles remain in the dishwasher, you may need to replace the turbidity sensor by removing it from the sump pump assembly.
