<p>A method for making clear ice comprising: filling a water sump to a predetermined level; contacting a refrigerant to an evaporator; circulating water from the sump over the evaporator to form ice on the evaporator; monitoring the water level in the sump; and monitoring the conductivity of the water in the sump to determine if the conductivity of the water is equal to or greater than a predetermined conductivity valve, (i) if the conductivity is not equal to or greater than the predetermined conductivity valve and if the water level reaches a predetermined lower water level, then complete the ice making cycle and initiate the harvest cycle; or (ii) if the conductivity is equal to or greater than the predetermined conductivity valve and if the water level has not reached a predetermined lower water level, then add additional water to the water sump.</p>
