Why is My Hoshizaki Ice Machine Beeping?

Hoshizaki ice machines use a series of beeps to help communicate if there is a problem in the system. Hoshizaki KM-series ice machines use a series of seven beep codes to alert users and technicians to all sorts of issues like high temperatures, low water flow, and low power. The first three beep codes are the most common ones we see when troubleshooting your Hoshizaki ice machine.

Head over to our blog for an in-depth guide on Hoshizaki beep codes.

Troubleshooting a Hoshizaki Ice Machine 1 Beep Alarm

A 1 beep alarm will sound anytime the thermistor in your ice machine reaches 127-degree Fahrenheit. The most likely causes for a Hoshizaki 1 beep alarm are:

  • Hot water entering the ice machine
  • Water not reaching the ice machine
  • Issues with the hot gas valve

Troubleshooting a Hoshizaki Ice Machine 2-Beep Alarm

A Hoshizaki 2-beep alarm signifies a log harvest cycle. The harvest cycle is the time when your ice machine begins to drop ice off the evaporator and into your ice machine’s storage compartment or ice bin. There are a few reasons why a Hoshizaki ice machine would sound a 2-beep alarm.

Troubleshooting a Hoshizaki Ice Machine 3-Beep Alarm

A Hoshizaki 3-beep alarm occurs during a long freeze cycle. During the freeze cycle, a Hoshizaki ice machine will run water over the evaporator where it drops to freezing temperatures to produce ice. A lot of issues can cause a 3-beep code like mechanical issues, refrigeration problems, or improper care for the ice machine.

How Much Ice Should My Hoshizaki Ice Machine Produce?

Hoshizaki ice machines often show two different production rates, Maximum and AHRI. Maximum capacity denotes the maximum amount of ice the machine can produce provided ideal air and water temperatures stay at 70 degrees and 50 degrees respectively. AHRI capacity is the amount the machine will produce if air and water temperatures are raised to 90 and 70 degrees.

How Do I Shut Off a Hoshizaki Ice Maker?

Sometimes while troubleshooting your Hoshizaki ice machine, problems can arise that will require you to shut the unit down. This can be due to a running leak or electrical issues. Below is a step-by-step guide to shutting off your Hoshizaki ice machine.

Why Is My Hoshizaki Ice Maker Leaking?

Leaks are one of the most common ice machine issues. Leaks can stem from a variety of places – and not always from the ice machine. If you notice water pooling around your ice machine, it’s a good idea to find exactly where the leak is coming from. You can save yourself money on a service call by calling the right expert for the job.

Why Is There Mold in My Ice Machine?

Every ice machine, Hoshizaki or otherwise, has the potential to attract mold and slime. Mold and slime are attracted to damp, dark environments. Furthermore, they feed off of organic material floating in the air. If you run a bakery or brewery, which both use a lot of yeast, your ice machine will attract mold faster. Regular cleaning will also help prevent accidental contamination of your ice supply from germs that can make people sick.
