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.

We’re no strangers to Hoshizaki 3-beep alarms. We’ve serviced over 20,000 commercial ice machines and counting. The vast majority of the time, Hoshizaki 3 beep alarms are completely avoidable.

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 automatic ice machine’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, a Hoshizaki ice maker has 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. Our Hoshizaki ice machine cleaning guide can help you create an ice machine cleaning schedule to follow.

Preventive maintenance is so important to commercial ice machines, we include it in all of our ice machine subscriptions. We’ve found that providing at least two preventive maintenance and cleanings per year greatly increases the lifespan of commercial ice equipment and can prevent issues that lead to Hoshizaki 3 beep codes.

Cleaning is the best way to prevent ice maker error codes. Read this guide for all you need to know about cleaning your Hoshizaki ice maker.

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 industrial ice maker 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.

    1. Hello Shiva. Thank you for reaching out!

      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. Definitely call a technician to help you address this.


  2. I also have the 3 beeps again, last year it was doing the same thing and I took it to a professional and after about 400.00 it’s working great until about Christmas, they said it was the thermister, what now? I love this machine, I’ve gone through the cleaning cycle and new water filter, cleaned all the other screens and it will run and make 2 harvest and go back into the 3 beeps mode,, I can reset it and it will harvest maybe 1 more time and then no more until morning,, it’s a 120 about 10 years old, not a minute of trouble until last year,, I keep it cleaned and use ice,, can you help me?

    1. Hey Floyd. Thank you for reaching out.

      I’m sorry to hear you’re having issues with your ice machine.

      Without knowing the model of the equipment, it’s hard to say exactly what it could be. The 3-beep code is generally the most difficult to diagnose, however on the Hoshizaki Ice Machines, the thermistor is not normally the culprit. We are also unfamiliar with a Hoshizaki Ice machine that has the model number “120.” We would be happy to assist further with additional information.

  3. Yeah my work has one that’s beeping 3 times. It doesn’t make ice so I’m not sure what the issue is.

  4. My Hoshizaki will start cycling for 3-5 hours creates a batch of ice then shuts down starts beating 3 times. Any help on this??

    1. There could be many reasons for the three-beep error code, and the reason is likely also why the ice machine is not producing ice the way it should be. You can read the bulleted list above for troubleshooting. But often the cause of 3 beeps hard to diagnose. The ideal solution would be to call an ice machine technician. We offer ice machine service in some parts of the country or you can go online and use reviews to find a reputable servicer near you. Good luck!

  5. Ice maker km1301 what cause compressor got too cold and making noise internal it csuse. By bad TXV.

    1. Hello Jorge,

      This is certainly a symptom of a TXV (thermostatic expansion valve) failure but not necessarily the reason for the cold, noisy compressor. There are additional components within the refrigeration system that could present similar symptoms. Freezing plate separation, improper refrigerant charge, hot gas valve leaking by. Depending on the compressor noise, it may need replacing as well.

      In any case, an experienced commercial ice machine technician should be able to pinpoint the problem.

      Good luck!

      1. I installed a brand new out of the box Hoshizaki approximately 2-3 months ago. Machine worked fine until recently. The deadly 3 beeps. Hoshizaki said it was a water problem. I had installed a new filter the day the machine went into service. Checked filter as per Hoshizaki recommendations. Still beeps. Weird thing is it would make a full bin even while beeping. Checked second filter as per Hoshizaki’s recommendation. Still beeps. Drained the water trough and cleaned it. Some very fine grit but cleaned it out. Then flushed new clean water through it. Worked for two days now beeps again and only made 3/4 bin of ice. WHY. This is driving me and the owner wacky. What have I overlooked. Dave

        1. Dave, There are many reasons the 3-beep alarm can be activated. The model number of the machine would be helpful in directing you to the most common reasons for the 3-beep, extended freeze alarm to be activated. Can you please provide additional information so we can provide more useful advice?
