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

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

Troubleshooting a Hoshizaki One-Beep Alarm

A Hoshizaki two-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 produce a two-beep alarm, and we cover all of them in the guide linked below.

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. There are a range of mechanical issues that can cause a 3-beep code, such as a sticking float switch, refrigeration problems, or improper care for the ice machine.

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.

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.

How to Shut Off Your Hoshizaki Ice Machine

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 My Ice Maker Leaking?

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 business that uses a lot of yeast, you're much more likely to find mold growing in your ice maker. Regular air filter cleaning will also help prevent accidental contamination of your ice supply from germs that can make people sick.

A variety of problems can cause your ice machine to produce less ice than it should, without completely halting production. Water inlet valve defects are a common source of these issues. Besides causing internal mold growth, a leaking water valve can reduce ice output by reducing the incoming water flow rate. Hot water migration or an excessively high incoming water temperature can also contribute to a high internal temperature and low ice production.

Another cause of low output is an excessively high ambient temperature. It might seem ironic, considering that hot days are when you need ice the most. However, the ideal ambient condensing temperature for an ice machine is around 70 degrees Fahrenheit. Make sure that the space around your ice maker is well-ventilated, and keep it in a temperature-controlled space if possible.
