C2648 Prodigy and Prodigy Plus Service Manual Water The quality of the water supplied to the ice machine will have an impact on the time between cleanings and ultimately on the life of the product. There are two ways water can contain impurities: in suspension or in solution. Suspended solids can be filtered out. In solution or dissolved solids cannot be filtered, they must be diluted or treated. Water filters are recommended to remove suspended solids.
C2648 Prodigy and Prodigy Plus Service Manual Panel Removal 1. Locate and loosen the two screws at the bottom edge of the front panel. Install the bin top adapter if one is required for the application. 2. Pull the front panel out at the bottom until it clears the bin. If the ice machine has not been unpacked, do so now.

The sump empty light should come on, and if the unit is on the inlet water solenoid valve will open to fill the reservoir.
C2648 Prodigy and Prodigy Plus Service Manual Temperature Sensors 1. Check controller. If the sensor calibration is completely out of range, the code display will read either 5 or 7. 2. Check with an ohmmeter. Open control box cover, unplug sensor from J6. Water temperature probe: Measure the temperature of the water. Push and release the clean button. Wait one minute.
C2648 Prodigy and Prodigy Plus Service Manual Water Pumps Test using the controller’s indicator lights. 1. Check the indicator light during the freeze cycle. The light will be On for all but the 30 second anti-slush period, so observe the light for one minute. When it is On, check the water pumps, both should be operating. If only one is operating check for voltage to that pump, if there is no voltage, replace that pump.
C2648 Prodigy and Prodigy Plus Service Manual Purge valve Test using the controller’s indicator lights. 1. Shut unit off by holding the Off button for 3 seconds. 2. Wait four minutes. Push and release the On button, observe the Purge Valve indicator light. As the unit drains the reservoir, the purge valve will be powered. When it gets power, the indicator light will be ON. If the purge valve does not open to drain the reservoir when its indicator light is on, do a voltage check. 3.
C2648 Prodigy and Prodigy Plus Service Manual Compressor contactor Test using the controller’s indicator lights. 1. When the unit is in ice making mode the compressor contactor will have power. Check the Compressor indicator light, when it is on the compressor contactor will have pulled in. If it is not, do a voltage check. Place voltmeter leads on the coil of the contactor. 2. There should be full voltage . If there is full voltage present and the contactor has not pulled in, replace the contactor.
C2648 Prodigy and Prodigy Plus Service Manual Pressure switch High pressure cut out. The high pressure cut out switch will open at a preset pressure, shutting off power to the compressor contactor. After the pressure has fallen to another preset level, the switch will re-close and the contactor coil will be energized. To Test High Pressure Switch: A. Attach refrigeration gauge set to high side port. B. Disconnect leads to fan motor. C. Measure voltage at high pressure control. D.
C2648 Prodigy and Prodigy Plus Service Manual Liquid Line Solenoid Test using the controller’s indicator lights. 1. Put the controller into test mode (depress Off for 3 seconds then depress Clean for 3 seconds). At the end of the test cycle, the liquid line valve will be powered and the Condenser Fan motor indicator light will be on. The liquid line valve should be open at that time. 2.
C2648 Prodigy and Prodigy Plus Service Manual Inlet Water Solenoid Valve Test using the controller’s indicator lights. 1. Shut unit off by holding the Off button for 3 seconds. Wait four minutes. 2. Push and release the On button, observe the Water Solenoid indicator light. After the unit drains the reservoir, the inlet water valve will be powered to refill the reservoir. When it gets power, the indicator light will be ON.
C2648 Prodigy and Prodigy Plus Service Manual Harvest Assist Test using the controller’s indicator lights. Harvest Assist Solenoid - No Longer Used on This Model Push and release the Harvest button. The Hot Gas indicator light will be on. At the same time the Harvest Assist Solenoid will be powered. If the ice on the evaporator is thin, the solenoid will extend.
C2648 Prodigy and Prodigy Plus Service Manual Reservoir Removal The reservoir may be removed from the cabinet if needed. 1. Drain water by holding in the Clean button repeatedly until no more water will drain. 2. Disconnect electrical power. 3. Twist counterclockwise and lift water pumps up and tip to one side. 4. Remove front water reservoir cover plate, set aside. 5. Remove sump cover and water level sensor, set sump cover aside. 6. Pull water reservoir forward; tip up and out of the machine.
C2648 Prodigy and Prodigy Plus Service Manual Controller Differences The controllers are programmed at the factory for the model they are installed on, they cannot be moved from one model to another due to differences in: • Water purge time per setting • Maximum harvest time • Number of evaporator plates • Prodigy Plus models have a connector for the lower light and switch panel. The service controller is OK to use on all Prodigy cubers without that connector.
