Turn the hinge upside down so that July 1999 Page 10 CSW45 Using The Ice Maker Understanding How Your Ice Maker Works When you first start your ice maker, the water pan will fill and the system will rinse itself before starting to make ice. The rinsing process takes about five minutes. Under normal operating conditions, the ice maker will cycle at preset temperatures. The ice level sensor located in the ice storage bin will monitor the ice levels. IMPORTANT 3. The water containing the rejected minerals is drained after each freezing cycle. 4. Fresh water enters the machine for the next ice making cycle. 5. Cubes fall into the storage bin. When the bin is full, the ice maker shuts off automatically and restarts when more ice is needed. The ice bin is not refrigerated and some melting will occur. The amount of melting varies with room temperature. · If the water supply to the ice maker is turned off, be sure to set the ice maker control to OFF. · The ice maker is designed to make clear ice from the majority of water sources on a daily basis. If your results are unsatisfactory, your water may need to be filtered or treated. Making Ice 1. Water is constantly circulated over a freezing plate. As the water freezes into ice, the minerals in the water are rejected. This produces a clear sheet of ice with a low mineral content. NOTE: As the room and water temperatures vary, so will the amount of ice produced and stored. This means that higher operating temperatures result in reduced ice production. Setting the Controls 1. To start the normal ice making cycle, select ON. 2. To stop ice maker operation, select OFF. 2. When the desired thickness is reached, the ice sheet is released and slides onto a cutter grid. The grid divides the sheet into individual cubes. NOTE: The CLEAN setting is used whenever solutions are circulated through the ice maker for cleaning. Only the water pump and compressor operate at this setting. See the "Cleaning the Ice Maker System" section. July 1999 Page 11 CSW45 Caring For Your Ice Maker Periodically inspect and clean the ice maker to keep it operating at peak efficiency and to prevent premature failure of system components. Both the ice making system and the air cooled condenser need to be cleaned regularly. The minerals rejected from the circulating water during the freezing cycle will eventually form a hard scaly deposit in the water system which prevents a rapid release of the ice from the freezing plate. 6. Push the selector switch to CLEAN. (See the "Setting the Controls" section.) The light will turn on, indicating that the cleaning cycle is in process. When the indicator light turns off (approximately 45 minutes), the cleaning cycle is complete. During the cleaning cycle, the system will both clean and rinse itself. 7. After the cleaning cycle is complete, remove the drain cap from the water pan to see if any cleaning solution is left in the water pan. If cleaning solution drains from the water pan, you should run the clean cycle again. Clean the ice and water system periodically to remove mineral scale buildup. Frequency of cleaning depends on water hardness. With hard water (15 to NOTE: Severe scale buildup may require repeated 20 grains/gal. [4 to 5 grains/liter]), cleaning may be cleaning with a fresh quantity of cleaning solution. required as frequently as every 6 months. 8. Push the selector switch to ON to resume ice Cleaning Exterior Surfaces production. Wash the exterior enamel surfaces and gaskets with warm water and mild soap or detergent. Wipe and dry. Regular use of a good household appliance cleaner and wax will help protect the finish. Do not use abrasive cleaners on enamel surfaces as they may scratch the finish. Cleaning the Ice Maker System 1. Push the selector switch to OFF. 2. Wait 5 to 10 minutes for the ice to fall into the storage bin. Remove all ice from the storage bin. 3.

This board takes in data from two thermistors: The Ice Bin Thermistor and the Evaporator Thermistor. The two resistances the thermistors supply, along with the position of the control switch, determine the cycles of the ice machine. Start Up The inlet water valve opens for about two minutes to fill the reservoir. The water pump starts and stays on for about a minute, then shuts off. Then the inlet water valve opens again for two minutes. After it closes, the compressor, pump and fan motor start. Freeze The compressor, fan motor and water pump are all operating and stay in a Freeze cycle until the evaporator thermistor reaches 6.5oF. That signals the control board to place the unit into a harvest cycle. Harvest The compressor and hot gas valve are both powered during the harvest cycle. The fan and pump are OFF. The machine stays in the harvest cycle until the evaporator thermistor senses 52oF. If the bin is not full, the unit goes into another freeze cycle. Bin Full The unit will shut down when the ice level sensor senses a temperature of less than 35oF. It will restart when the thermistor's temperature increases to 41oF. Clean The Clean Cycle lasts about 47 minutes. During the first minute all motors and valves will be switched on in sequence for 5 seconds each. This includes the inlet water valve, condenser fan, hot gas solenoid valve, water spray pump and the compressor. This early portion of the Clean Cycle doubles as a diagnostic cycle. The last 46 minutes of the clean the compressor, water spray pump and hot gas valve will be on.

Remove the three screws holding the cutter grid cover to the grid. 3. Remove the screw holding the grid to the right side of the liner. Loosen This Screw Remove This Screw 4. Loosen, but don't remove the screw holding the grid to the left side of the liner. Lift the front of the grid until the slot in the grid clears the screw, the pull the grid forward and out of the cabinet. Control Box 2. Disconnect the three wiring harness plugs from the control box. The control box is located above the cutting grid. It is suspended from the top panel by 4 screws. Its wiring harness routes out the back of the control box through a molded channel. Remove 3 Screws Wire Harness Plugs July 1999 Page 22 CSW45 Repair Information Water Slide Fan Motor The fan motor and/or blade is only accessible after The water slide is mounted to the front of the the cabinet has been tilted up. evaporator and diverts water to the reservoir. It is connected to the evaporator by two screws. Remove Component Compartment Access the cutter grid first to get access to it. Reservoir The reservoir is located below the evaporator, and is mounted to the bin liner with two screws. Water Pump The water pump is located below the evaporator. It is mounted to the bin liner with three screws. It also has a quick-connect electrical plug. Evaporator Thermistor This thermistor is a set of two red wires that connect to the control box. There is a molded portion in one of the wires with a clip on it. That portion clips onto the part of the suction line under the middle of the evaporator that runs front to back. Screws Note: Chassis does NOT pull out. Unplug the unit from the power supply. If built in, pull it out from the counter. Note: The water and drain lines may have to be disconnected. Screws Leveling Leg 1 Remove the front panel. 2. Remove the leveling legs from the cabinet. 3. Remove two screws at the front holding chassis base to cabinet. Compressor 4. Tilt the entire ice maker back far enough to gain The terminals for the compressor are accessible only access to the compartment. from the back of the unit. Compressor replacement requires lifting up of the cabinet at the front.
