Hoshizaki 3 Beeps Easy Ice

Believe it or not, a Hoshizaki ice machine has its own language. Beep codes help provide hints when ice machines are not running as they should. When this happens, the unit shuts off to prevent damage and alerts the user with a beep code. Many issues can cause Hoshizaki 3 beeps to occur.

In this article, we’ll tell you the core reason for Hoshizaki ice machine 3 beeps and what you should do if you ever encounter one.  

What Causes Hoshizaki 3 Beeps?

Simply put, when a Hoshizaki ice machine 3-beeps a code, it means your ice maker has had two elongated freeze cycles in a row. Before we talk about “elongated” freeze cycles, let us first explain what a freeze cycle is.  

The freeze cycle is the stage in an ice machine’s production cycle where water begins to flow over a cold evaporator plate. As this happens, the water freezes and becomes ice. The length of the freeze cycle depends on air and water temperatures, but the amount of water in your ice machine’s reservoir also plays a large part. As water cascades over the ice machine’s evaporator plate, ice forms and the water level in the reservoir drops.  

Your ice maker’s float switch monitors when the water level reaches a designated low point. When the water reaches that limit, the float switch signals the end of the freeze cycle and starts the harvest cycle, where ice is collected. 

An “elongated” freeze cycle is what happens when an issue prevents the above conditions from occurring, keeping the ice machine in its freeze cycle for too long. To prevent freeze cycles from running indefinitely, Hoshizaki ice machines have a factory-set timer (the time differs between models) that counts down the length of the freeze cycle. If the freeze cycle exceeds the limit of the timer, the circuit board inside the unit forces the ice maker to harvest the ice.  

When two consecutive forced harvests occur, it means an issue, either mechanical, environmental, or a combination of both, is causing the freeze cycle to run too long. At this point, the Hoshizaki ice machine 3 beeps, then shuts down to prevent damage.  

Troubleshooting Hoshizaki 3 Beeps

Hoshizaki 3-beeps are some of the hardest to diagnose. It may be a single problem or combination of issues that cause an extended freeze cycle. Some examples include, but are not limited to: 

  • Mechanical problems: 
    • Clogged check valves 
    • Leaky water inlet valves 
  • Refrigeration problems: 
    • A hot gas valve stuck open 
    • A low amount of refrigerant in the system 
  • Problems caused by improper care: 
    • Dirty air filters 
    • Dirty Condensers 
    • Overly hot temperatures 
    • Lack of ventilation 

The list goes on, but the good news is you can prevent some of these situations from occurring.  

Making sure your ice machine is running under proper temperature conditions is your first line of defense. That means keeping the surrounding air as close to 70 degrees Fahrenheit as you possibly can.  As far as water is concerned, ideally you want the temperature close to 50 degrees. Water temperature is much harder to control than air temperature, but there are some things you can do if the water is too hot or too cold. 

Preventive maintenance is your next course of action which includes regular cleaning of air filters and condensers.  

Regularly maintaining and cleaning your ice maker can be daunting, so you may want to hire a professional.  

What to Do if You Encounter Hoshizaki Ice Maker 3 Beeps 

If your Hoshizaki ice maker 3-beeps a code, you can be sure something is wrong. Hoshizaki 3 beeps don’t go off in error.  

Diagnosing them without professional help is difficult, but there are some common causes to look for.  

If you have an air-cooled system, check to see if dirt is clogging your air filter. If so, rinse the filter with soap and water and reset your ice maker. However, if your air filter is dirty then there’s a good chance your condenser is dirty as well, which will lead to underlying problems that can harm your ice machine if it’s not cleaned soon. In this case, it’s a good idea to get a professional cleaning.  

Try checking your room temperature, as well. If your ice machine is in a room over 90 degrees Fahrenheit, this could be the cause. Try lowering the thermostat on your air-conditioning unit. Ideally, you want the temperature around your ice machine to always stay around 70 degrees. 

Finally, make sure your ice machine is getting proper ventilation. If it’s in an enclosed room, try opening the door and use a fan to blow the hot air out of the room, while keeping the cold air from your AC inside.  

If none of these tips prevent your machine from shutting down, you should call a professional. It could be an issue with your plumbing or inside the ice maker itself.
