Soil sensing is performed in all wash cycles except the Rinse only cycle. Mounted on the right side of the sump, the soil sensor transmits light from a transmitter to a receiver to measure the amount of soil in the water. This information will be used by the control to determine the length of the cycle.
Once pre-wash loosens food on the dishes, the motor stops for 30 seconds. This allows the wash water and food soils to settle for the soil sensor to check the soil levels in the water.
Now that this reading is taken, the dishwasher drains the dirty water and fills again for the pre-wash rinse. Once this rinse is complete, the wash motor pauses again, a soil level measurement is again taken. The control uses these readings to adjust the wash cycle to ensure a clean load of dishes.
