Plastic tubing can be used, but may leak with age. Installation Location: Unit can be installed freestanding or enclosed. The front of the unit must be unobstructed for proper air circulation and operation at all times. Area should be ventilated with temperature above ©2003 Maytag Appliances Company 115 VAC, 60 Hz., single-phase power is Use ¼ inch saddle shut-off valve. Check to make sure valve complies with local codes. Do not use self-piercing saddle valve or less than ¼ inch saddle valve as water flow will be restricted. A quality system water filter or local water filter is recommended. A quality filter can remove particles as well as remove unpleasant taste and odors from water. Softened water is not recommended. Depending on mineral concentrations, this can produce mushy white cubes that may stick together. The above materials can be found at most local plumbing supply stores or hardware stores. Follow the manufactures installation instructions for water valves and water line hook-ups. Make certain the waterline and the valve do not leak prior to enclosing cabinet. 16022217 Rev. 0 5 Installation Instructions Gravity Drain The drain tube from the ice maker is 5/8 inch ID. This can be routed to a gravity drain in the area shown below or to a remote gravity drain that is located below the ice maker. Be sure to check your local codes. Slope any long horizontal runs according to code to remote gravity drain for proper drainage. An air gap may be necessary for horizontal runs over 4 feet. Proper routing, sloping, and size of drain line is important especially if using flexible tubing, or poor ice production will result. If installing a standoff gravity drain, use Illustration below for location. Standpipe can be up to 3 inches high above the floor. Route tubing from ice maker into the drain pipe. See Appendix A, owners guide, for additional drain information. It may be necessary in some installations to wrap drain tubing with wrap-type insulation. Condensation can form on the drain tubing and cause water damage. Drain Pump Drain Pump can be used to drain water when gravity drain is not available. As with the gravity drain, it may be necessary to wrap the drain tubing from the ice maker to the inlet of the drain pump with wrap-type insulation. Condensation can form on the drain tubing and cause water damage. 6 16022217 Rev. 0 ©2003Maytag Appliances Company Operation Instructions Operation. Selector switch is in the ON position. The assumptions before proceeding are that water is supplied to the ice maker, there is proper electrical power to the ice maker, and the drain is properly plumbed or the drain pump is operating properly. Input power must be applied at all times for proper operation. Any interrupt will lockout the compressor for up to 9 minutes and restart the mode of operation. Below is the timing diagram/operation for the electronic control. Upon setting the switch to the ON position, the water solenoid will energize for 1.5 minutes and then deenergize. When the bin thermistor senses temperature at or above the start ice setpoint, and the evaporator thermistor senses temperature at or above the production setpoint, the production cycle will begin. The circulation pump, condenser fan, and compressor relay will energize. When the evaporator thermistor senses temperature at or below the harvest setpoint, the harvest cycle will begin. The circulation pump and condenser fan outputs will be de-energized and the hot gas solenoid and the drain solenoid will energize. The drain solenoid will remain energized for 45 seconds and then de-energize, after which the water solenoid will energize for 2.0 minutes and then de-energize. Loads will remain in this state until the evaporator thermistor temperature rises to the production setpoint. Once the evaporator thermistor temperature is at or above the production setpoint, a new production cycle will begin. If at any time the bin thermistor senses a temperature at or below the stop ice setpoint, any production or harvest cycle in process will continue until the harvest cycle is complete. Once complete, all loads will de-energize and remain so until the bin thermistor senses a temperature at or above the start production setpoint. A new production cycle will then begin. During the first production cycle only (the switch was previously in the OFF or CLEAN position), the evaporator thermistor temperature will be ignored until the circulation pump has run for 2 minutes. During all harvest cycles, the evaporator thermistor temperature cannot terminate the harvest cycle until the water solenoid is de-energized. The grid cutter output will always be energized during the harvest cycle, and for the first 35 minutes into the production cycle. If during any production cycle or harvest cycle, the selector switch is put into the CLEAN position, any cycle in process will be immediately terminated and a clean cycle will occur. The unit will now repeat the entire above cycle. If during any production or harvest cycle, the selector switch is put into the OFF position, the cycle in process will be stopped and all loads will de-energize and remain so as long as the selector switch remains in the OFF position. If during any production or harvest cycle, the selector switch is taken out of the ON position, a lockout will be started during which the compressor relay will not reenergize regardless of switch position. If during any production or harvest cycle, there is a power loss/interruption of greater than 25 milliseconds, a lockout delay will begin and the compressor relay will not re-energize upon re-application of power until the lockout delay is complete. The lockout delay begins with the loss of power and is unaffected by duration of power loss. All other loads will operate normally during the lockout. The setpoints are as follows: Stop ice: 35.0 deg. F +/- 2 deg. F Start ice: 43.0 deg. F +/- 2 deg. F Harvest: 11.0 deg. F +/- 2 deg. F Production: 45.0 deg. F +/- 2 deg. F Setpoint vs Temperarure and voltage (120VAC): +/- 3 deg. F Operation. Selector switch is in the Clean position. The assumptions before proceeding are that water is supplied to the icemaker, there is proper electrical power to the icemaker, and drain is properly plumbed or the drain pump is operating properly. Refer to timing/operation diagram. Upon setting the selector switch to the CLEAN position during the production or harvest cycle, the water solenoid will energize and all other loads will be de-energized. The following sequence will now occur: 1. After 3.0 minutes the water solenoid will deenergize and the circulation pump will energize. 2. After 30 minutes the circulation pump will deenergize and the drain solenoid will energize. 3. After 75 seconds the drain solenoid will deenergize and the water solenoid will energize. 4. After 3.0 minutes the water solenoid will deenergize and the circulation pump will energize. 5. After 10 minutes the circulation pump will deenergize and the drain valve will energize. 6. After 75 seconds the drain solenoid will deenergize. The clean cycle is now complete. All loads will remain off as long as the selector switch ©2003Maytag Appliances Company remains in the "Clean" position and the power is not removed and reapplied. 16022217 Rev. 0 7 Operation Instructions If at any time during a clean cycle the selector switch is moved from the CLEAN position, all loads except the drain solenoid will de-energize (this includes the OFF position). The drain solenoid will energize for 75 seconds and then de-energize. The unit will now operate normally according to whether it is in the OFF or ON position. * 8 16022217 Rev. 0 ©2003Maytag Appliances Company Component Testing To avoid risk electrical shock, personal injury, or death, always disconnect electrical power source to the freezer before attempting to service, unless test procedures require power to be connected. When removing any wiring from terminals they must be replaced on the same terminals. Ensure all ground wires are connected before certifying unit as repaired and/or operational. ! WARNING Refrigeration System Test Procedures The following should always be practiced with any sealed system that is opened. Only open the sealed system as the final diagnosis. Check all basic areas such as wiring, water supply, drain setup, proper airflow first. Many times these areas can resemble sealed system problems. The diagnosis of a sealed system problem can be determined by accurate pressure and temperature measurements. 1. Use a leak detection system that will detect R-134A refrigerant. Leaks need to be found on any leaking system before repair takes place. 2. The drier must be replaced anytime the sealed system is opened. Failure to use correct part will result in repeated sealed system failure in the near future. 3. Limit time the system is opened. DO NOT EXPOSE OPEN SYSTEM FOR MORE THAN 15 MINUTES. This will result in sealed system failure. Leave replacement parts sealed and/or pressurized until ready to install. 4. The compressor must be replaced if there is a low side leak. Moisture has been drawn into the system if the unit has been running for extended period of time. Be sure to flush the system with dry nitrogen gas and evacuate to 50 microns before re-charging. 5. A new evaporator assembly must be ordered if the capillary tube is found to be plugged or severely restricted. Restrictions cannot be flushed out. 6. Be sure to purge the system after final brazing. This will flush out any air or moisture that may have entered the system before being absorbed into the ester oil. Low Side Leaks Low side leaks consist of a break in the system at the evaporator, low side (suction) return line, or accumulator. If a leak is found in any of these areas, moisture has probably entered the system. The compressor, drier, and hot gas valve will have to be replaced and the system will need to be flushed thoroughly with nitrogen gas and ©2003 Maytag Appliances Company evacuated to 50 microns before recharging. High Side Leaks High side leaks consist of a break in the system at the condenser, high side tubing, drier, or capillary tube. If a leak is found in any of these areas, the system can be flushed with nitrogen gas, evacuated to 50 microns, and recharged. Restricted Capillary Tube Moisture or other contaminants that enter the system can cause deposits in the system. These deposits will usually collect in the capillary tube and form a restriction that cannot be completely removed by flushing. If the capillary tube is found to be restricted, the evaporator, compressor, condenser and drier should all be replaced. Access Valves A temporary access valve can be used to service or evaluate the system. The access valve can be installed on the compressors process tube (this will also be a lowpressure side). Be sure to cap off access valve while servicing. This will prevent contamination of the system and/or refrigerant from leaking. After servicing, the access valve should be removed. A pinch-off tool can be used to close the system to remove the access valve and then braze the hole for the access valve to seal the system. Be sure to leak check after brazing. Pressures and Temperatures There are three ways to measure the temperature of the evaporator plate. 1. Use a thermocouple to measure the temperature of the evaporator. The thermocouple must be secured to the evaporator. The best and accurate location for the thermocouple end is where the thermistor is secured to the evaporator. Allow anywhere from 5°8°F of variation in measured temperatures if you measure on the plate because of the thermal conductivity of stainless steel thermistor in comparison to the thermocouple. 2. If it has been determined that there is proper contact between the thermistor and the evaporator plate, the thermistor resistance value can be corresponded to the temperature . 16022217 Rev. 0 9 Component Testing To avoid risk electrical shock, personal injury, or death, always disconnect electrical power source to the freezer before attempting to service, unless test procedures require power to be connected. When removing any wiring from terminals they must be replaced on the same terminals. Ensure all ground wires are connected before certifying unit as repaired and/or operational. ! WARNING 3. If it has been determined that there is proper contact between the thermistor and the evaporator plate, the voltage at the thermistor terminals can be read. The voltage can be read while the unit is running by attaching test leads to thermistor terminals at the electronic control. The temperature to switch into the harvest cycle is 11.0 °F and the corresponding voltage is 3.0-3.1 V. The temperature to switch into the production cycle is 45 °F and the corresponding voltage is 1.9-2.0 V. Slight variations in actual measurements can occur due to input voltage variations. Note:The temperature and pressure readings must be taken with unit on and water flowing over the evaporator plate (in the production cycle). Use gage pressure readings from the compressors process tube (low side) access valve. During production cycle, low side pressures will vary from 125 psi to 3 psi, depending at what point measurements are taken. High side pressures can range from 425 psi to 25 psi also depending at what point measurements are taken. In evaluating this system, the best point to determine if pressures are correct is at the end of the production cycle. This is the point where there is a thick slab formed on the evaporator and the evaporator thermostat is near cut-out temperature. If low side pressure is below pressure, check for the following: 1. A system leak 2. Capillary tube is restricted 3. Insufficient compressor If low side pressure is above pressure, check for the following: 1. Restricted air flow 2. Dirty condenser coil 3. Leaking or energized hot gas valve 4. Overcharged system 5. Low side leak Recharging Recharging of the unit should be done only after diagnosing and repairing the system (see Sealed System introduction). Be sure to flush the system with dry nitrogen gas and evacuate to 50 microns before recharging. The method for recharging the unit is by weight 10 using vapor refrigerant. Using manifold gauge setup, hook up charge hoses to the access valve on the compressors process tube. If any access valve was attached to the high side process tube, remove it and seal the tube by brazing before charging. Charge the unit to 5.0 oz (0.313 lbs.) of R-134A. After recharge, check pressures. Refer to Table A for corresponding temperatures and pressures. If pressures or temperatures are incorrect, check the sealed system, recover the charge, repair, evacuate, and then recharge. NOTE: It is not uncommon to have some condensation or a slight frost on the suction line. This may occur towards the end of the production cycle. Liquid refrigerant is not getting into the compressor if the unit was charged properly. It is important that the insulation remains on the suction line and the capillary tube together after any repair and that it is sealed at both ends. Hot Gas Valve The hot gas valve is used to bypass the capillary tube and send warm gas to the evaporator when opened during the harvest cycle. The valve is actuated by a solenoid that opens the valve when energized and closes when de-energized. The valve seats using gravity so the valve must remain vertical to fully close. A faulty hot gas valve will result in long ice production cycles and higher than normal low side pressures. The valve usually fails by being stuck in the open or closed position, or by not fully seating in the closed position causing the valve to leak-by. A contaminated system or damage to the valve body will cause any of these failures. Care in keeping the system clean, handling the valve, keeping the valve cool during brazing, and evacuation of the system before charging must be done to prevent damage and eventual failure of the valve. A quick way to check the valve to see that it opens and closes freely (with the system still sealed) is to repeatedly energize and de-energize the solenoid and listen for the valve opening and closing. You should be able to hear a distinct click of the valve opening and closing. If you can not hear this, then the valve is stuck and will need to be replaced. The solenoid coil itself can be check by measuring resistance across the electrical terminals. A resistance reading of 380-390 ohms should be found in a good solenoid coil. 16022217 Rev. 0 ©2003 Maytag Appliances Company Component Testing To avoid risk electrical shock, personal injury, or death, always disconnect electrical power source to the freezer before attempting to service, unless test procedures require power to be connected. When removing any wiring from terminals they must be replaced on the same terminals. Ensure all ground wires are connected before certifying unit as repaired and/or operational. ! WARNING Evaporator The evaporator uses evaporating refrigerant to remove heat from the water that flows over the evaporator plate to form an ice slab. The ice slab will simply slide down the evaporator plate onto the grid-cutter during harvest. The evaporator plate will over time have a build up of mineral deposits. The evaporator will not need to be replaced due to the mineral deposits. These deposits must be removed periodically for proper icemaker performance. The evaporator must also be free of nicks and scratches. A nice polished and smooth evaporator will allow the ice machine to perform correctly, giving the best performance by allowing the ice slab to slide freely and allowing the water to have proper evaporator to water contact. If nicks and scratches are found, replacement is not needed. Simply remove the nicks and scratches with fine sanding material and then use a polish for stainless steel. If the evaporator has a leak, it should be replaced. A leak detection device will confirm a leaking evaporator assembly. Note: If a leak in the evaporator, accumulator, or low side tubing is found, the compressor, drier, and hot gas valve will need to be replaced. The temperature control thermistor sets on the bottom of the evaporator plate on a copper bracket. This bracket should be checked at the solder joint. Any cracks will break the proper thermal conductivity between the evaporator plate and the thermistor and result in long production cycle with a thick slab on the plate. The thermistor should also be secured tight and have full contact to the copper bracket or thermal conductivity again will be sacrificed. Compressor The compressor is the heart of the refrigeration system. It also, however, relies on other parts of the system to function. Make certain that the other parts of the system are correctly functioning before determining that the compressor is faulty. ©2003 Maytag Appliances Company Note: The compressor is protected from power interruptions with a start delay built into the control to prevent high pressure startup DO NOT mistake this for a faulty compressor. The following must also be observed before concluding the compressor is faulty: 1. Low high side pressures, warm evaporator plate, cool condenser coil, or little or very low current draw from the unit will indicate a faulty compressor. 2. Check for continuity between the compressor terminals and the shell of the compressor. If continuity is found, the compressor is faulty and will need replaced. 3. Check for resistance between all three compressor terminals. The resistance will vary from terminal to terminal and from compressor to compressor due to age and use. If no resistance is found, the compressor is faulty and will need replaced. Condenser The condenser is a steel tube serpentine with copper alloy fins, which removes heat from hot, high-pressure vapor from the compressor. The most common trouble is lack of airflow from either a restricted intake or exhaust opening in the front of the unit. Lint, dust, hair, and dirt build-up needs to be removed from the condenser periodically to allow the unit to perform properly. It is possible that the condenser might need replaced because of an un-repairable leak or a restriction that cannot be flushed out. System high side pressures and temperatures will verify if this is the case. Drain Valve The drain valve drains water that is left in the reservoir after ice production. The valve will only be open for a fixed time of 45 seconds during the beginning of the harvest cycle. The drain valve fails by allowing water to flow into the drain during the ice production cycle (leak-by). This is can be caused by a foreign particle(s) or build-up of mineral deposits that will not allow the valve to fully seat or has caused damage to the seat of the valve. Periodic cleaning of the icemaker will keep build-up off valve allowing it to work properly and should be done before further evaluation of the valve. 16022217 Rev. 0 11 Component Testing To avoid risk electrical shock, personal injury, or death, always disconnect electrical power source to the freezer before attempting to service, unless test procedures require power to be connected. When removing any wiring from terminals they must be replaced on the same terminals. Ensure all ground wires are connected before certifying unit as repaired and/or operational. ! WARNING Symptoms of this include thin or no ice slab (depending on severity of leak) and, more noticeably, water draining through to the drain during the ice production cycle (do not mistake this for reservoir run off water or melted ice drain water from the ice bin). The drain valve should be replaced if it is found to be leaking. The drain valve solenoid actuator can also possibly fail. Test the solenoid by checking the resistance. A resistance of 50-65 ohms should be found. If no resistance is found, the drain valve will need to be replaced. Water Valve The water valve supplies water to the reservoir for producing ice. The valve opens for 1.0 minutes during initial start-up of the unit and opens for 2.0 minutes in the harvest cycle after the drain valve has closed. The valve has a built-in screen in the water supply fitting. This screen will filter out any large particles and, over time, these particles will accumulate and restrict water supply. If this is found, simply clean the screen with a toothbrush to remove the particles. DO NOT REMOVE THE SCREEN FROM THE VALVE. To check the water valve: 1. Check the solenoid actuator for resistance. If no resistance is found, the valve will need to be replaced. 2. Check to see if the valve will seat properly. Foreign particles that may have passed the filter could damage the seat of the valve. To make sure the valve is seating, make sure power is disconnected to the unit, hook up the water supply, turn on the water supply, and see if there is any water flowing in the water lines. If water is present and flowing, the valve will need to be replaced. 3. Check the flow rate of the reservoir water line. Using a stopwatch or a watch with a second hand, see what amount of time it takes to fill up a one-quart container. The time should be 60 seconds to get the .25-gpm specifications of the valve. If it takes substantially less than 60 seconds, check the water supply pressure to make certain it is not above 120-psi static pressure. If it is not, the metering orifice of the valve has been changed and the valve will need to be replaced. 12 If it takes substantially more than 60 seconds, check the water supply pressure to maker certain it is not below 20-psi static pressure. If it is not, make certain the valve screen filter is clean. If the filter is clean, replace the valve. Condenser Fan The condenser fan is used to force air over the condenser coil. The fan will run only during ice production cycle and turn off in ice harvest cycle. To check the condenser fan: Make sure motor shaft turns freely. This can be done by rotating the fan blade by hand and observing any excessive resistance. Check for resistance between terminals. If no resistance is found, replace the condenser fan. Check for continuity between terminals and fan casing. If continuity is found, replace the condenser fan. Check current draw. Typical current draw will be .15 amp without fan resistance. If current draw is .19 amp or more, check for resistance in air movement or objects touching the fan blade. If this is not found, then replace the condenser fan. Thermistors This unit utilizes two thermistors for reading temperatures for input to the electronic control. Each thermistor has a different function for input to the electronic control. Evaporator Thermistor The evaporator thermistor is made up of a stainless steel body and is secured to the under side of the evaporator. The location of the thermistor allows the thermistor to give voltage input to the electronic control. This input is processed through the electronic control to switch the ice maker into the production or the harvest cycles. The thermistor must be tightly secured to the evaporator bracket for proper heat transfer. The following will happen in the event of a thermistor failure: 1. If an evaporator thermistor fails, all loads will be shut off and the unit will not run. 16022217 Rev. 0 ©2003 Maytag Appliances Company Component Testing To avoid risk electrical shock, personal injury, or death, always disconnect electrical power source to the freezer before attempting to service, unless test procedures require power to be connected. When removing any wiring from terminals they must be replaced on the same terminals. Ensure all ground wires are connected before certifying unit as repaired and/or operational. ! WARNING 2. If the evaporator thermistor senses temperature outside of 0-140 deg. F, all loads will be shut off and the unit will not run. The thermistor can be check by use of a multi-meter with the ability to read resistance. To check the thermistor: 1. Disconnect and remove the thermistor from the unit. 2. Use a reference temperature point that is known (such as an ice bath) and measure the resistance across the wire leads. 3. Check the recorded resistance with that in the table below. If measured resistance falls outside the resistance given in the table within 4% of the value, the thermistor is bad and will need to be replaced. RESISTANCE VS. TEMPERATURE CHART TEMPERATURE (C) TEMPERATURE (F) RESISTANCE (KOHMS) -15 5 11.350 -10 14 8.918 -5 23 6.700 0 32 5.630 5 41 4.520 10 50 3.652 15 59 2.970 20 68 2.430 25 77 2.000 If the thermistor has been tested and is found to be good then check the temperature of the evaporator plate and the resistance of the thermistor. If the temperature of the evaporator plate does not correspond to a proper resistance from the thermistor then check for proper and secure connection of the thermistor to the evaporator plate bracket. The use of a heat sink compound can be used between the thermistor and the evaporator bracket if needed. Grid-Cutter Transformer Grid-Cutter The grid-cutter is used to cut cubes from the ice slab formed on the evaporator. It uses low voltage, 12VAC, to heat the wires. Wires are warm to the touch of a hand when not under the load of a slab of ice. The grid-cutter is on only from the start of a harvest cycle to 35 minutes from the start of the production cycle. There is no repair for the grid-cutter. It will have to be replaced as an assembly. To test the grid-cutter: Check the resistance at the outside grid-cutters plug-in terminals Note: The middle terminal is not used. If the resistance between the terminal of the plug is 5.0-5.9 ohms, the grid-cutter is good. At any other resistance readings, it will need to be replaced. Check for continuity between terminals and the grid-cutters stainless steel frame. If continuity is found, check for wires that are not on the insulators. Reservoir The reservoir retains the water needed to produce an ice slab. It will hold a maximum of 3 quarts of water. Anything over 3 quarts will be drained in the reservoirs overflow. Anytime the reservoir is removed, it should be cleaned with ice machine cleaner. Be sure to rinse the reservoir before re-installing. Circulation Pump The circulation pump is used to circulate the water in the reservoir over the evaporator. The circulation pump will run only during ice production cycle and turn off in ice harvest cycle. The pump is a centrifugal impeller type pump. The pump and motor are an assembly that cannot be repaired separately. To check the circulation pump (with the pump removed): Make sure motor shaft turns freely. This can be done by rotating the pumps drive shaft and observing any excessive resistance. Check for resistance between terminals. If no resistance is found, replace the circulation pump. Check for continuity between the hot and neutral terminals and the pumps motor casing. If continuity is found, replace the circulation pump. Check current draw. Typical current draw will be .36 amp without pump resistance. If excessive current draw is found, check the pumps impeller for foreign particles or severe build-up of mineral deposits. The grid-cutter transformer is used to step down the voltage to the grid-cutter to 12 VAC. The transformer is on only from the start of a harvest cycle to 35 minutes from the start of the production cycle. The transformer itself can be checked by applying 120VAC to the marked 120V (for the hot lead) and COM (neutral lead) side of the transformer and reading the 12V side using a multimeter. If no readout is found or readout is below 10VAC, replace the transformer. ©2003 Maytag Appliances Company 16022217 Rev. 0 13 Troubleshooting To avoid risk electrical shock, personal injury, or death, always disconnect electrical power source to the freezer before attempting to service, unless test procedures require power to be connected.

See the Care and Cleaning section (page 11). IMPORTANT: If the water supply to the ice maker is turned off, be sure to set the ice maker control to OFF. How Your Icemaker Works Your ice maker is unique in forming ice. It uses fractional freezing to form a slab of ice that is clear and has less mineral content than the water it is produced from. This is accomplished by running water over the cold evaporator plate which gradually freezes the water to produce the ice slab. Mineral deposits are left in the reservoir. When the ice slab reaches the correct thickness determined by the temperature of the evaporator plate, the electronic control switches to the harvest cycle to harvest the ice slab. During the harvest cycle, the ice slab falls from the evaporator to the ice grid cutter. Here, the ice slab is cut into 3⁄4" squares by the grid cutter’s low voltage heated wires. During the harvest cycle, the drain valve will remain open for 45 seconds to drain the reservoir of remaining deposits. After that, the water valve will open for 2 minutes providing 2 quarts of water to the reservoir for the next ice production cycle. 10 The ice maker will keep producing ice until the ice maker’s bin is full and will restart automatically when ice needs to be replenished in the bin. Due to variables in installation and use, individual results may vary. Room and water supply temperatures affect the output of ice. Ice will also melt away, especially at the start of an empty bin, but this will slow down as ice accumulates. NOTE: When using the ice maker for the first time, discard at least the first two harvests of ice cubes. 41007621 JA Ice Maker ENG 4/28/03 2:18 PM Page 11 Care and Cleaning CAUTION WARNING • Avoid leaning on the cabinet door, you may bend the door hinge or tip the ice maker. Both the ice making system and the condenser need to be cleaned regularly. 6. Replace front cover panel and close door. 7. Switch selector switch on the grill of the machine to the CLEAN position. Three quarts of water will automatically be added to ice maker cleaner. Cleaning the Ice Maker System Some impurities and minerals will remain and build-up in the ice maker and stick to the ice maker’s parts over time. This build-up must be removed for proper ice production, ice quality, and ice maker life. Your ice maker is equipped with a cleaning mode that will help in cleaning out these impurities. Clean the ice and water system at least annually to remove buildup. Frequency of cleaning depends on water hardness. With very hard water ( >14 gpg), cleaning may be required as frequently as every 6 months. 8. The total cleaning time will end in approximately 49 minutes. The cleaning cycle will automatically rinse the evaporator plate and also drain the cleaning solution and rinse water. 9. After the cleaning cycle has ended, remove the front cover panel again and check that build up has been removed. The evaporator plate should be clean, shiny, and smooth to the touch. If not and build up is still visible, repeat the cleaning cycle above. If build up is removed, continue below. 10. Disconnect power to the ice maker. CAUTION To clean the ice maker: 1. Switch the selector switch to the OFF position (see page 13). • Read and follow manufacturer’s warnings on ice machine cleaner products. Personal injury can result when used improperly. O N O F F C L E A N 2. Wait approximately 10 minutes for the ice to fall into the storage bin. Remove all ice from the storage bin. 3. Remove the drain plug at the bottom of the reservoir to drain any remaining water and then reinstall. 4. Unscrew and remove interior stainless steel front cover panel to gain access to the reservoir. 5.
