Follett ice machines are renowned for their reliability and the high-quality ice they produce, particularly in healthcare and foodservice environments. Whether you are using a Symphony Plus dispenser or a Horizon Elite series maker, these machines are designed for heavy-duty use. However, even the most durable equipment requires regular maintenance and occasional repairs to function at peak efficiency.
Understanding how to care for your ice machine can prevent costly downtime and ensure that you always have a steady supply of clean, safe ice. This guide provides a comprehensive overview of routine maintenance, troubleshooting common issues, and how to identify the correct replacement parts for your specific model.
Why Follett Ice Machines Stand Out
Follett is perhaps best known for its proprietary “Chewblet” ice. This compressed nugget ice is highly sought after because it is easy to chew and holds the flavor of beverages well. Beyond the ice quality, these machines are engineered with advanced features like antimicrobial protection and self-flushing systems.
Because these machines are often used in medical settings, they are built to meet rigorous sanitation standards. Maintaining these standards requires a proactive approach to cleaning and part replacement. By following a consistent schedule, you can extend the lifespan of your investment significantly.
Routine Maintenance for Peak Performance
Regular maintenance is the most effective way to avoid unexpected breakdowns. Most Follett machines require a deep cleaning and sanitizing every six months, though high-traffic environments may need more frequent attention. Always refer to your specific user manual for model-specific instructions.
Cleaning and Sanitizing Your Machine
Cleaning removes mineral scale, while sanitizing kills bacteria and viruses. To clean your machine, you should first turn off the ice production and drain the water system. Use an approved nickel-safe ice machine cleaner to circulate through the evaporator and water lines.
Once the cleaning cycle is complete, the sanitizing process begins. This involves using a food-grade sanitizer to ensure all surfaces that touch water or ice are sterile. Remember to discard the first few batches of ice produced after a cleaning to ensure no chemical residue remains.
Descaling the Evaporator
Mineral buildup, or scale, is the primary enemy of ice machine efficiency. If you live in an area with hard water, minerals like calcium can coat the evaporator, making it harder for the machine to freeze water. This leads to longer cycle times and increased wear on the gear motor.
Regular descaling involves using a specialized solution to dissolve these minerals. If you notice your ice cubes are smaller than usual or the machine is running louder, it is likely time to descale the internal components.
Managing Water Filtration
The water filter is your first line of defense against contaminants. A clogged filter restricts water flow, which can cause the machine to shut down or produce cloudy ice. You should replace the water filter cartridges at least every six months, or sooner if the water pressure drops.
Troubleshooting Common Follett Ice Issues
Even with perfect maintenance, mechanical issues can arise. Knowing how to diagnose basic problems can save you the cost of a professional service call. Here are some of the most common issues reported by users.
The Machine Is Not Starting
If the machine appears completely dead, first check the power source and the circuit breaker. Many Follett dispensers also have a bin signal or a safety switch that prevents the machine from running if the bin is full or if a panel is not properly secured.
Check the control board for any error lights. Most modern Follett units feature a diagnostic display that will flash a specific code. These codes are usually listed on the back of the front panel and can tell you exactly which sensor or motor is failing.
Low Ice Production or Slow Cycles
Slow production is usually caused by restricted airflow or water flow. Check the air filter and the condenser coils for dust and debris. If the machine cannot shed heat, it will take much longer to freeze the water.
Additionally, check the water inlet valve. If the valve is partially clogged with sediment, the reservoir will fill slowly, delaying the start of the next ice-making cycle. Cleaning the valve or replacing the internal screen often solves this problem.
Unusual Noises During Operation
A squealing or grinding noise often indicates a problem with the gear motor or the auger. In Follett machines, the auger rotates inside the evaporator to scrape off the ice. If the bearings are worn or if there is excessive scale buildup, the motor will struggle and make noise.
If you hear a loud humming but no movement, the motor may be seized. This is a critical issue that requires immediate attention to prevent the motor from burning out entirely.
How to Identify and Order Replacement Parts
When a part fails, getting the exact replacement is vital. Using generic parts can void your warranty and may lead to further damage to the machine. Follett components are engineered to precise tolerances.
Locating Your Model and Serial Number
Before searching for parts, you must find the data plate on your machine. This is typically located on the side or back of the unit, or behind the front cover. You will need both the model number and the serial number to ensure compatibility.
Parts for older units may differ significantly from newer versions, even if they share the same model name. Having the serial number allows parts suppliers to look up the specific “build version” of your equipment.
Essential Parts to Keep on Hand
If you manage a facility where ice is critical, such as a hospital or a busy restaurant, it is wise to keep certain “wear parts” in stock. This allows for immediate repair without waiting for shipping.
- Water Filters: As mentioned, these should be changed regularly.
- Bin Sensors: These infrared sensors tell the machine when to stop. If they fail, the machine may overflow or stop making ice entirely.
- Water Inlet Valves: These are prone to wear and mineral blockage.
- O-rings and Gaskets: These small rubber components prevent leaks and should be replaced whenever you disassemble a component for cleaning.
Safety Tips for DIY Repairs
While many maintenance tasks are easy to perform, safety should always be your priority. Always disconnect the power supply before opening the machine or touching electrical components. Water and electricity are a dangerous combination.
If your machine uses a specific refrigerant, do not attempt to repair the cooling lines yourself. Federal law requires a certified technician to handle refrigerant gasses. If you suspect a leak or a compressor failure, it is time to call a professional.
Conclusion
Maintaining a Follett ice machine is a straightforward process that pays off in the form of longevity and consistent ice quality. By keeping the unit clean, changing filters on time, and addressing minor issues before they become major failures, you can ensure your equipment serves you well for years to come.
