I have a Scotsman dce33pa 1sc ice machine. My problem is the water will not shut off. The pump continually pumps water out. I replaced the inlet water valve but that did not help.
In all likely hood there is a sensor or switch assembly that detects when the cube trays are filled and that then cuts off the drive signal to the inlet water valve when they are filled. Your failure is likely to be this sensor being broken, missing or out of adjustment.
The sensor could be any number of types and will depend entirely upon the nature of the design of your particular ice maker. It could be a mechanism that detects the water level, detects the increased weight of the tray as it fills or uses ultra sound or light to detect the the water level. Your challenge will be to comprehend what is used in your unit either by reading its repair manual or by opening the unit and making an inspection. In either case you will then be able to infer how it is failing to work properly. Sensor replacement or adjustment would be the next course of action.
