Basics things to check yourself along with a couple of cautions.
Why my ice machine is not working or is under producing! Commercial ice machines are convenient and time-saving for providing cold drinks and food in bars, restaurants, hospitals, schools, office buildings, and homes. However, they can also be troublesome if they malfunction or break down. Fortunately, there are some simple steps to troubleshoot and repair a commercial ice machine that won’t cost you anything.
Note that most service calls for ice machines that are not operating well are due to maintenance and cleaning issues. Always CLEAN and sanitize the ice machine!
Please also note that a tiny percentage of unscheduled service calls are due to the refrigeration system. If you see someone with refrigerant charging manifolds heading for the ice machine, please stop them. Those gauges will do far more harm than good at this point. Ice machines are critically charged, and any alterations to the refrigerant charge will have a negative effect. Critical charging is a precision science requiring a Professional Ice Machine Technician with good factory guidance beforehand.
Here are some simple steps to take before calling for service.
First, make sure the ice machine has power. Check the outlet and make sure it is plugged in and turned on. Check if it is plugged in to see if a breaker or fuse was tripped. If it’s not plugged in or powered on, you’ll need to reset the breaker or replace the blown fuse before continuing.
The first necessary ingredient of ice is water. As you will discover throughout this section, water is both a necessary ingredient and the most significant liability of ice machine ownership. Water controls handle the processes of manipulating water processing inside the ice machine. If any water controls break, there is a high likelihood of property damage due to flooding or severe damage to the ice machine due to freezing. It is essential to appropriately inspect and maintain each water control and component to guard against the potential for damage.
Next, make sure the machine is getting enough water. Check the supply line to ensure it is connected and not leaking anywhere. If a pressure regulator is on the line, ensure it is adjusted correctly to have adequate water pressure for the ice maker to function properly. Also, check to see if there are any blockages or contaminants (pressure drop) in the water filtration that could prevent water flow.
- A competent service technician is needed if the ice machine is running and obviously freezing but has no running water. This issue can be complex (expensive) to diagnose and make needed repairs.
- The ice machine water system is designed to be robotic and often requires bi-directional water pumps controlled by sensors (thermistors) and a digital control system. These systems are dependable yet complex. Wrong diagnostic thinking is expensive, unreliable, and requires a competent technician.
Third, inspect the condenser and evaporator coils for any signs of damage or contamination. These two components are partially responsible for providing essential refrigeration to freeze the water in the ice machine. If they are dirty or blocked, they will not be able to function correctly and can cause significant problems.
- The condenser coil(s) is subject to airborne dust and dirt contamination.
- The evaporator is subject to dissolved and undissolved contaminants from the inlet water supply.
Finally, ensure the ice bin is empty and free of frozen chunks or clogs that could cause the machine to malfunction. If there is an issue with the ice dispenser, check to see if it’s stuck or jammed due to a blockage or obstruction. If so, remove the item and ensure all moving parts are free and clear of debris.
By following these simple steps, you can avoid costly service calls and ensure that your commercial ice machine runs smoothly and efficiently. However, if all else fails, it’s best to call a professional technician knowledgeable in commercial ice machines for further assistance. Ideally, find a certificated Professional Ice Machine Technician.
Summary:
- Commercial ice machines are an efficient and convenient way to provide cold drinks and food in bars, restaurants, hospitals, schools, office buildings, and homes. They are complex and require seemingly endless patience while maintaining or repairing them and waiting for the assorted cycles of the sequence of operation complete.
- Before calling for service, check to ensure the machine is plugged in and receiving power; inspect the supply line for any blockages or contaminants; clean and sanitize the machine; inspect the condenser and evaporator coils for any damage or contamination. Be sure that a significant call for ice has not been made beyond the capacity of the ice machine.
- If all else fails, call a professional technician who is certified in commercial ice machines. With their help, you can ensure that your machine runs smoothly and efficiently.
- Taking these steps can help you avoid costly service calls down the line and save you time and money.
