#1 Lack of quality water filtration for your ice machine

Commercial ice machine repair can seem like a daunting task, when you partner with the right commercial ice machine company, they can absolutely be repaired. The most common problems with commercial ice machines typically stem from hard water problems and the lack of a quality ice machine water filter. Hard water entering ice machines can cause an ice maker a lot of problems. Hard water will cause scale to build up inside an ice machine. Scale can cause parts like water inlet valves and water dump valves stick open or closed. This can lead to ice machines overflowing with water if the inlet valve fails open or cause all your water to be pumped down the drain if the dump valve fails open. If your water inlet valve seizes closed due to scale build up, your ice machine will trip off on an error due to low water. Ice machine dump valves that fail closed will not cause an ice machine to stop because of an error, but the ice machine will become extremely dirty very quickly, because it can’t get rid of dirty water. Calcium and magnesium, the minerals that make up hard water, also known as scale, can cause more problems than just to inlet and dump valves. Scale can cause pumps to seize up and the plastic inside the ice machine to become coated with a thin layer of scale build up. Manitowoc and Scotsman ice machines use an ice thickness probe to tell the ice machine when there is ice ready to be dropped off the ice making grid, or evaporator, into the ice bin. When these thickness probes get covered in scale, it causes them to be less sensitive to ice production and cause the commercial ice machine to make very thick ice. A good ice machine water filter can help keep scale from causing your ice machine to break.

#2 Lack of basic commercial ice machine maintenance

Other things that can cause a commercial ice machine to stop making ice is the condenser. The condenser is designed to move ambient air over a thin aluminum coil to move the heat from the ice machine. This is what helps get the ice makers evaporator below freezing so that it can make ice. When the fan motor goes out or the condenser gets dirty, it can cause the ice machine to shut down because of high pressure. Just like the radiator on a car, the ice machine will get too hot and shut down on a safety error. Condensers can be located inside an ice machine or remotely. Remote ice machine condensers are typically outside on a roof. The condensers on the roof tend to get stopped up with dirt faster due to being outside and may need to be washed out with a water hose more often depending on your location. In West Texas where the dirt blows a lot, condensers need to be cleaned much more often.

#3 Refrigeration issues causing your ice machine to shutdown

Another reason ice machines can fail is due to refrigeration issues. Refrigeration issues can be caused by the failure of a mechanical switch like a fan cycle control that keeps the condenser fan motor running or a compressor going out. Hot gas valves can get stuck and keep the ice maker from harvesting ice off the evaporator, or the thermostatic expansion valve, or TXV, can fail and keep the commercial ice machine from making ice at all. Ice machines also have high pressure controls that can cause the ice machine to shut down to keep from damaging the compressor if the condenser fan motor fails. The failure of the fan cycle switch can also cause the high-pressure control to trip. Ice machine failures can be exacerbated when ice machines are not properly installed.

#4 Improper commercial ice maker installation

Improperly installed ice machines can cause a variety of problems with ice machines from minor nuisances to major failures. Proper air flow around an ice machine can cause the ice machine to starve of fresh air and run hotter than normal. This can cause the ice machine to take longer to make ice and eventually develop a refrigeration issue due to consistently running hotter than designed. When the ice machine drain lines are installed incorrectly, it can cause the ice maker to keep from draining properly and the machine will become dirty prematurely. If an ice machine doesn’t have a proper ground, it can cause the control board to incorrectly interpret sensors and probes and cause the machine to shut down on various safety errors. Properly installed electrical grounding on an ice machine can solve a myriad of issues.
