Sensing/Soaking The dishwasher senses the soil level on the dishes. Soil level determines the length of some cycles, the amount of heat added to the wash and the number of rinses needed in the cycle for the load. It also senses the temperature of the water during thermal hold water heating periods. SENSING/SOAKING glows during the soil sensing and thermal hold portions of the cycle.
