Watch this video to learn about the features of Hoshizaki Flakers/DCMs as well as some of the maintenance procedures to keep your machine up and running.

Before we begin the basic operation, let's look at some of the features and benefits that make Hoshizaki machines so dependable and serviceable. Regular maintenance checks and servicing are made easier with the KM Cuber's removable panels. The component sections are divided into separate compartments, free from the damaging effects of moisture. Separating the evaporator, or wet section, from the dry electrical components of our machines helps eliminate many problem areas. Dividing these compartments also helps insulate the heat generated by the compressor from the cold section, making the KM Cuber more energy efficient. Unlike other ice makers on the market, the KM Cuber's pump motor is housed in a separate insulated compartment away from the moisture of the evaporator, reducing corrosion, bearing, and winding failures. At the heart of our pump assembly is a more efficient, permanent split capacitor motor. This assembly can be easily removed and rebuilt in the field. The sealed evaporator section has a smaller ice drop zone than other ice makers. During operation, positive air pressure helps to reduce the air flow around the evaporator, keeping airborne bacteria out and reducing algae growth. Many manufacturers build evaporator plates in welded sections of copper, which are plated with nickel or tin. Plating the copper is necessary for sanitation and to allow the ice to harvest properly, but it may flake and peel from the copper with age, contaminating the ice. The unique plate design of Hoshizaki's evaporator with its stainless steel freezing surface and oval-shaped serpentine tubing produces a crystal clear, crescent-shaped hard cube of ice which displaces more liquid than square or diced cubes. Since pure water freezes first on the evaporator plate, minerals are left to run off into the reservoir, reducing scale buildup and saving frequent and expensive cleaning. Some of the benefits of the KM Cuber that help make your job easier include removable panels, separate compartments, an insulated evaporator section, a rebuildable pump assembly, a small ice drop zone, and a unique stainless steel evaporator. Now, let's look at the basic sequence of operation of the Hoshizaki KM Cuber. When the power switch is turned to the "Ice" position, the inlet water valve opens, allowing water to enter and fill the reservoir. The one-minute fill cycle assures that the ice machine will not start until there is sufficient water, eliminating overheated pumps and compressor problems. After one minute, the controller board checks to see if the float switch is closed, and if not, repeats the fill cycle until the water level is sufficient. The float switch check also occurs at the end of each harvest cycle to ensure continuous, automatic low water safety. When the switch is closed, the controller starts the initial harvest cycle which runs approximately 2-3 minutes depending on ambient air and water temperature. First, hot gas from the compressor enters the serpentine coils of the evaporator, while the inlet water valve remains open to assist in the harvest. This causes any ice remaining from the previous cycle to be released from the plate, while water continues to fill the reservoir. Starting the compressor in the harvest cycle with the hot gas valve open provides a no-load start, better efficiency, and longer life of the compressor and components. When the thermostat senses that the evaporator temperature has reached 48 degrees Fahrenheit, the solid state defrost completion timer on the circuit board takes control of the remainder of the harvest cycle. During the harvest cycle, the inlet water valve brings water through the supply tube and down the center of the evaporator plates. This water flow also helps transfer heat from the serpentine coils to the stainless steel plates and pre-chills the water flowing into the reservoir. During the freeze cycle, water is pumped to the outside of the plates through the distributor tubes. In the freeze cycle, the hot gas and water valves are closed. As the self-contained condenser fan and pump motor starts, water is circulated up and across the outside of the evaporator plate and back down into the reservoir. The circuit board controls the freeze cycle for the first five minutes, providing short cycle protection. The float switch then assumes control to initiate the next harvest. If power to the machine is interrupted, the unit will always restart in the one-minute fill cycle. Before the second harvest, a 10-second pump-out cycle occurs. As the hot gas valve opens, allowing gas to warm up the evaporator, the pump motor stops for two seconds then begins again in reverse. This pumps out the water containing concentrated minerals from the bottom of the reservoir through the check valve and out the drain. At the same time, water is used to power flush the float switch. For improved cleaning, the pump-out timer on the circuit board may be adjusted to lengthen the cycle to 20 seconds. It can also be adjusted to occur every 1, 2, 5, or 10 cycles. These adjustments provide the service technician with the flexibility to overcome some problems associated with the high mineral content present in some local water supplies. When the pump-out cycle is completed, the pump motor stops and the inlet water valve opens. Just as in the initial harvest, the evaporator is warmed by the hot gas defrost and water assist, clearing any ice left frozen on the plate as the reservoir then refills in preparation for the next freeze cycle. The water level in the reservoir always overflows the stand pipe at the end of the harvest cycle. On top of the stand pipe is a displacement cap, which pulls additional minerals from the bottom of the reservoir and flushes them. This cleaning action can be extended by lengthening the defrost completion timer setting. When the bin is filled with ice, the machine automatically shuts off until more ice is needed. Let's review the basic sequence of operation: the ice maker always starts with the one-minute fill cycle. The initial harvest cycle clears ice from the plate, assures a full reservoir, and allows quick and easy compressor starting. After five minutes in the freeze cycle, the float switch assumes control to initiate the next harvest. The 10-20 second pump-out cleans the reservoir every 1, 2, 5, or 10 cycles. The normal harvest is the same as the initial harvest and allows the flush to clean the reservoir at the end of this cycle. For Tech Support, call 1-800-233-1940.

Award-winning products combined with an extensive sales and service network make Hoshizaki the right choice. Hoshizaki stands out from the completion in three key areas: 1. Stainless steel exterior throughout our entire product line, 2. Stainless steel ice-making surface, and 3. Individual cubes. Ice is one of the most important items served in any food and beverage operation. And if you don't think so, see what happens when you run out. Ice is no longer one size fits all. The latest trends show that operators are demanding a variety of ice to meet each site application. Perhaps it's the cube ice for beverages, or flaked ice for seafood displays; it's important to know which type of ice is just right. At Hoshizaki, we offer three styles of cube ice: our signature crescent cube, the IM square cube, and our AM gourmet cube (or "top hat" shape). Let's look at each type in more detail so you can determine how to specify "just right" for the operation. Our crescent cube has been called the world's most perfect ice for good reason. Our exclusive design produces a hard, pure, crescent-shaped ice cube. Cuber ice machines have features which differentiate it: the stainless steel flat ice-making surface is durable with long-lasting construction. This makes it easy to clean and produces clear, pure cubes. Individual square cubes are designed for the discriminating customer. These hard, large cubes are a favorite of mixologists for adult beverages and specialty drinks. Top hat-style cubes provide a hard individual gourmet ice. They are perfect for offices, residential, rooms or suites, outdoor kitchens, and healthcare. In the flake category, we offer the traditional fine-flaked ice and cubelets, a larger chewable ice. Ice is formed in a barrel-type cylinder, moved upward through an extruding head, producing a dry, flaked, or cubelet ice. Available in a wide variety of configurations, our cubelet ice offers fast cooldown with good displacement. It's a customer favorite because it absorbs beverage flavors, allowing them to linger on your taste buds. Popular in produce and seafood displays, as well as healthcare, our flaked ice is a moldable ice that quickly cools down and maintains freshness of foods. All Hoshizaki models have a stainless steel exterior, providing the perfect combination of sophistication and durability. Hoshizaki is Energy Star Partner of the Year. At Hoshizaki, our performance says it all. We rank the highest in efficiencies in our reported product categories for Energy Star. Hoshizaki: The right choice.

This video will demonstrate the proper way to perform a system diagnosis on flaker ice maker units. Before we cover how to diagnose electrical and component failures, let's review the flaker's sequence of operation. The sequence of operation is controlled by a series of timers within the solid state timer board. First, the flaker begins a startup when the flush switch is set to the ice position and the power switch is set to the on position. Power is then supplied to the inlet valve, allowing water to fill the reservoir. The unit will not begin the ice making process until the reservoir is filled. Next, when the dual float switches indicate a full reservoir, the bin control takes over and allows the unit to sequence up. At this point, the gear motor and condenser fans start. Should the gear motor experience undue stress from the rotating auger or the pressure of ice extrusion, the machine will automatically shut down through the gear motor protect relay, saving wear on the gear motor and bearings. After one minute, the compressor starts. This delay allows any ice left in the evaporator cylinder to be removed before basic refrigeration begins. As the refrigeration cools the water in the evaporator, ice begins to form on the cylinder wall within two to three minutes. The gear motor turns an auger inside the stainless steel cylinder. As ice forms on the inside wall, the auger breaks away the ice and moves it upward. The upward pressure extrudes the ice out the top of the cylinder and into the bin. Ice production will continue until the bin is full. Once the bin is full, the ice pushes against the bin control paddle. The paddle operates a magnetic proximity switch and a shutdown process begins. Within six seconds after the bin control indicates a full bin of ice, the gear motor, compressor, and fan stop. Self-contained units and DCMs sequence down. One minute after the bin control opens and indicates a full bin of ice, the compressor stops. One minute later, the gear motor and fan stop. Before beginning the diagnostics on a flaker ice maker, it's important that you first make sure there is proper water and power supplied to the unit. When troubleshooting for system failures, first remove the covers of the unit. Place the flush switch to the ice making position and turn the machine on. Remember, the unit will not start up unless the reservoir is full and both float switches are closed. If the water valve does not energize, check the water valve terminals for voltage. A meter reading of 24 volts indicates that the water control relay circuit is supplying power to the water valve. This means that the problem is either the water valve coil is open, the valve is stuck closed, or the water valve screen is plugged with debris. At this point, turn off the power supply and shut off the water supply. Remove the thumb nut and check for debris plugging the inlet stream. Next, check the coil for continuity with an alm meter. Replace the water valve if it is defective. Some flaker models have a built in periodic flush. The flush valve is operated either by the manual flush switch or by the 12 hour flush timer. If no power is supplied to the water control circuit at start up, it could be off on the 12 hour timer. You can advance the timer or check the timer contacts with the volt meter to determine if this is the case. After checking the flush timer, if there is no power to the inlet water valve, check the controls transformer secondary to make sure control voltage is present. You can easily check the secondary and circuit fuse by removing the control box cover and checking across terminals one and two on the timer for 24 volts. If control voltage is present, check the flush ice switch for contacts. If the water valve is energized and the reservoir is over flowing, check both float switches and the water control relay. To check the float switch, twist and lift the assembly out of the reservoir. The float switch has three wires: black, red, and blue. First, check the blue and black or common wire with your meter at the control box connector. When you raise the bottom float, the switch should be closed. When it is down, the switch should be open. Now, check the red and black wires. The float switch should again be closed when the top float is up and open when it is down. If the float switch needs to be cleaned, soak it in ice machine cleaner. If you take it apart, mark the top of the floats and be sure to replace them in their original position. This will allow you to have the correct timing on the water control relay circuit. To check the water control relay, review the wire color code on the wiring diagram and check the relay with your meter. When the reservoir fills and the water valve stops, the gear motor and condenser fan should start. If this does not occur, locate the bin control terminals on the timer board. Check the bin control's proximity switch by disconnecting the wires from these terminals. Check the wires with an alm meter to assure that the bin control is closed. Another way to check the proximity switch is to use a jumper. If you jumper across the bin control circuit pins five and six and the machine starts up, the bin control proximity switch is your likely problem. The terminal numbers may vary on older models. Always verify the terminal numbers on the unit wiring diagram. The solid state timer board controls the entire sequence of operation. To diagnose a bad timer board, first check across terminals one and two. You should have 24 volts or the machine will not cycle up. Then, jumper across terminals three and four. If the machine starts up, you should check your water control relay circuit as previously discussed. If the machine still doesn't start, other circuits must be checked before condemning the timer board. Now, jumper across terminals five and six to check the bin control. If the unit cycles up with the jumper in place, the board is good and the problem is with the bin control circuit. Check your wiring diagram to determine which voltage should be present at terminal eight. Depending on the model you are working on, this terminal could either be a line voltage or a controlled voltage circuit. If your meter reads the proper voltage, then the timer board is good and is supplying power to the gear motor relay or circuit. If the gear motor relay is not energizing at this point, it may have a bad coil or a mechanical problem. If the condenser fan is running and the gear motor is not, the relay is operating properly and there may be a problem with the gear motor circuit. If the gear motor and fan start but the compressor does not, check the gear motor protect relay. To check this circuit, jumper across terminals ten and eleven. If the compressor starts up within one minute, the problem is in the gear motor protect relay. If the compressor doesn't start after jumping ten and eleven, check the compressor circuit. To perform a quick check of the compressor circuit, turn the power switch off. Place a jumper across the black compressor relay on the timer board. This will bypass the timer and allow the compressor to start. Turn the power back on. If the compressor runs, the compressor circuit is okay. If not, use basic diagnostic procedures to check the compressor and start components. If the compressor circuit is okay, the timer board is probably bad and will need to be replaced. Remember, when servicing any Hoshizaki ice maker, always refer to your tech spec's guide for detailed information or call the Hoshizaki service hotline on your screen. Now that you have learned the various check out procedures, you should be able to diagnose most problems that occur with the flaker.

The following preventative maintenance check will help keep Hoshizaki Flakers and DCMs dependable and serviceable for many years. Clean the removable air filter. Service the water filter and check the water valve screen. Check for bearing wear once a year. Look for loose wires, oil spots, water drips, and other signs of wear or damage. Clean the exterior of the ice maker with a soft cloth and neutral cleaner. And clean and sanitize the water system and bin. Annual cleaning and sanitizing of the water system is recommended. More frequent cleaning may be needed if there is a high mineral content in the local water supply. Instructions for cleaning are located inside the front panel. To clean the flaker, drain the water system, turn off the control switch, and incoming water supply. Mix the cleaning solution as directed on the front panel. Remove the reservoir cover and fill with cleaning solution until it overflows into the stand pipe. Allow the cleaner to set for 15 to 20 minutes to loosen the scale buildup. Turn the control switch to “on” and the flush switch to “ice”. Allow the flaker to make ice with the cleaner solution until the low water safety operates. Place a container under the ice drop zone to catch the frozen cleaning solution and then discard in a safe place. Inspect the reservoir. If the reservoir is clean, the evaporator is clean. If not, repeat the entire cleaning process. When you are sure the system is clean, turn on the water supply and flush the system thoroughly with fresh water. The same procedure should be used to sanitize the unit using a commercial ice machine sanitizing product. After a thorough flush, turn the unit on and allow it to make ice. Catch the first 10 minutes of product and discard it to ensure your customers’ ice is fresh and clean.

Before we begin to describe the basic operation of the flaker and DCM models, let's look at some of the features and benefits that make Hoshizaki machines so dependable and serviceable. Removable panels make regular maintenance checks much easier. A solid state sequence timer provides automatic control over the continuous ice making process. Hoshizaki flakers and DCMs utilize and internal auger system with a direct drive spline coupled gear motor for dependable operation. A fully insulated stainless steel evaporator provides a durable freezing surface. Anti-magnetic stainless steel is used to eliminate pitting and corrosion on the evaporator and auger surface, helping increase efficiency and extending component life. The bearing are sleeve type alignment bearings. The carbon resin bearing material has a graphite base to provide lubrication eliminating possible grease contamination. The auger is driven by a sealed gear motor assembly which is protected by two overload sensing systems that protect against undue stress. A unique low water safety device developed by Hoshizaki shuts the unit down automatically if the unit switches fail to detect water in the reservoir. The unit will restart the ice making process only when the water level is restored. Removable panels, a solid state sequence timer, anti-magnetic, stainless steel evaporator and auger, carbon alignment bearings, a sealed gear motor with overload protection, and a low water safety device. Just some of the features and benefits of the Hoshizaki flaker and DCM models that help make your job easier. Now, let's look at the basic sequence of operation of the Hoshizaki flakers and DCMs. The complete start up and shut down process for the flaker is operated by a series of timing circuits built into the solid state timer board. With the power switch on and the flush switch in the ice position, the inlet water valve opens allowing water to fill the reservoir. The ice making process will not begin until the reservoir is filled. When the dual float switches indicate the reservoir is filled, operation is turned over to the bend controlled magnetic proximity switch. And if it is closed, the unit begins ice production. At this point, the gear motor and ice condenser start up. Should the gear motor not start, a gear motor protect relay will automatically shut the unit down to protect against any component damage. If at any time during operation, the sealed gear motor should experience stress which causes an excessive amperage increase, a manual gear motor reset protector will shut the unit down. After one minute, the compressor starts, this delay will allow any ice left in the evaporator cylinder to be cleared. As the refrigeration system clears the water left in the evaporator cylinder, ice begins to form and is extruded within two to five minutes. Ice production will continue until the bin is full. Once the bin is full, ice pushes against the control which opens the magnetic proximity switch and begins the shut down process. On the M model flaker the gear motor, fan, and compressor, stop within six seconds after the bin control indicates a full bin of ice. A time delay is used in the smaller flakers and DCM units to allow the gear motor to clear the evaporator of ice. On these models, one minute after the bin control switch opens, the compressor stops. One minute later the gear motor and condenser stop. The unit will now sit idle until the ice is scooped away from the bin control which will cause the proximity switch to close and restart the unit. Unique among Hoshizaki flakers, is the automatic flush period. Designed to provide cleaner operation and longer bearing life. The automatic flush is operated by a 12 hour timer. The flush feature can also be operated by a manual flush switch when periodic cleaning and maintenance is required. When the flush timer or manual switch is activated, the flaker unit switches off within two minutes. One minute after either switch opens, the compressor shuts down. Followed a minute later by the gear motor and condenser fan. Next the flush valve opens allowing the complete water system to drain while on the flush timer the unit remains off for 15 minutes. Any ice remaining in the evaporator melts and the evaporator walls and chamber are completely flushed out. During this time, the inlet water valve will not be activated. During normal operation, the auger rotates inside the evaporator cylinder to break ice away from the cylinder walls and move it up to the extruding head and cutter. Because the auger is one of the major moving parts in the ice maker, it must be checked periodically for excessive bearing wear. Although flaker bearings are constructed of carbon impregnated resin, they may wear due to high mineral or silica content in the water. If not replaced, excessive bearing wear may cause damage to the auger and evaporator cylinder. To remove the auger for inspection, drain the water system, remove the clear ice shoot head and ice shoot bracket. Next, remove the stainless steel bolt that hold the cutter to the auger. Replace the bolt and use it to rock the auger back and forth to check for excessive play. To check for bearing wear, attempt to slip the 20,000th inch feeler gauge available through Hoshizaki between the auger bearing surface and bearing. If the bearing gap is more than .02 inches, replace both the top and bottom bearings. To remove the auger for bearing replacement, remove the allen head cap screws and water seals which hold the extruding head to the evaporator cylinder. Using the bolt and a large washer, or the cutter head installed upside down to hold the auger, lift the auger and extruding head up and out of the evaporator cylinder. When the auger has been lifted out, remove the extruding head and visually inspect the auger bearing surface for wear. The sleeve bearings are pressed into the extruding head and lower housing. To remove the lower housing, remove the allen head cap screws which hold the cylinder to the housing. Loosen the belly band screw, and lift the evaporator up about four inches. Then, tighten the screw to hold the evaporator in place. The housing and cylinder are sealed with an O ring. Care should be taken to protect the O ring for reuse. Or replace it when necessary when reassembling the unit. Remove the bolts at the base of the housing and remove the housing to replace the lower bearing. Have the bearings repressed and replace the parts in reverse order.
