Are your ice cubes shrinking? Have you noticed smaller cubes coming out of your Hoshizaki ice maker? If your Hoshizaki commercial ice maker is producing smaller ice cubes, there is likely an underlying issue. The Ice Machine Experts at Easy Ice are here to help! We specialize in Hoshizaki ice machine service and want to share some of our knowledge with you.
Let’s walk through why you’re experiencing Hoshizaki ice cube production issues.
What Issues Cause a Hoshizaki to Produce Smaller Ice Cubes?
There are a few common reasons your Hoshizaki ice machine is producing smaller than normal ice cubes. They include:
- Not enough water flowing to your automatic ice machine.
- There is enough water at the start, but the water is leaking out of the ice cube maker in some way other than as an ice cube.
- The measurement device (the float switch) is adjusted to the wrong setting.
Some of these issues are due to plumbing and will require a plumber to solve. Others will require an experienced ice machine technician to fix.
Hoshizaki Producing Smaller Ice Cubes Due to Low Water Flow
The float switch is an ice machine component that helps tell a Hoshizaki ice machine to stop freezing water. As the machine’s reservoir fills, the float switch helps to monitor the amount of water in the reservoir.
Whether you have a large ice cube maker or a small ice machine, during ice harvest, the reservoir begins to fill with water. If it does, it should fill to the point where there is enough water in the reservoir for a full batch of normal sized Hoshizaki KM cubes. If it doesn’t fill, check the incoming water supply. A plugged external filter or inlet water valve screen could be the problem. If this is the case, you’ll need to call an ice machine technician.
Low water pressure or an improper inlet water line size is also a possibility. If this is the case, you’ll need to call an experienced plumber to solve the issue.
Hoshizaki Producing Smaller Ice Cubes Due to Leaks
If the reservoir filled properly during harvest, the water had to go somewhere, right? In this case, check for leak by at the pump-out check valve. Leaks can be caused by dirt, scale, or a weak spring.
A missing displacement cap or o-ring for the drain standpipe can also cause this issue. A water trail caused by shipping tape, an out of position ice chute guide, or algae can cause water to splash or run into the commercial ice bin.
There is also the remote possibility of a leaking reservoir. Search until you find the missing water culprit and correct it, and your ice cube size should return to normal.
If you’re experiencing issues like this and need someone to help diagnose your problem, give our helpful Ice Machine Experts a call. We can help you solve your industrial ice machine problem. If there is damage to the ice machine, like corrosion from an internal leak, it may be time for a new ice machine. Our ice machine subscription program can get your business a steady flow of ice from a new machine for little to no capital upfront.
Hoshizaki Producing Smaller Ice Cubes Due to Float Switch Issues
Finally, when looking at the float switch, you will see that it can be adjusted. The higher you adjust the switch, the smaller the cubes will become because the switch will tell the machine to stop freezing sooner. If you move the switch lower, the cubes will be larger because the switch will tell it to stop freezing later.
Be careful playing with this adjustment because if you make the cubes too large, they may bridge (i.e. start freezing to one another) which will give you all kinds of trouble with harvesting, freeze-ups, etc.
If your need help adjusting your float switch, our team can help guide you through the process.
Preventive Maintenance Can Help Prevent Small Ice Cubes
The best way to stop a Hoshizaki ice machine from producing small ice cubes is to keep up with preventive maintenance. During a preventive maintenance call, an ice machine technician will optimize the ice machine and replace any faulty parts. They will also perform any ice machine repairs that will get the machine up and running again.

6 Comments on “Reasons Why A Hoshizaki Ice Machine May Produce Smaller Ice Cubes”
Our small Hoshizaki ice machine in our office is making sheets of ice instead of individual pieces. We have had the machine for 3 years now and I’m sure it needs to be serviced.
Hi Becky,
Typically you should have your ice machine serviced at least 2 times per year, so if it’s been longer than six months since your last service, I would consider setting an appointment soon.
Hoshizaki ice machines are not known to produce sheets of ice and the severity of your problem will be dependent on the model type. Feel free to call us at 866-easyice and provide your machine details to one of our representatives. They will gladly help you get to the bottom of your problem.
Hi, We have a new machine installed. Problem is it won’t stop producing ice causing it to clog. The ice is also smaller than it should be and we see water dripping inside.
Hi Andrew,
There are a lot of reasons this could be the case, but without knowing the brand and model of the machine, it would be hard to accurately diagnose your problem. If you like, you can give our service number a call at (866) 327-9423 and we’ll help to find a solution.
Most all ice machine manufacturers provide a customer service number to call to help diagnose issues with their equipment.
I had my water filter replaced for my km650 hoshizaki.Then the water turned black and then the ice machine shut down.. So thinking it’s my water filter I got a new one and replaced it. And still machine won’t run
Hey Chance,
Depending on the type of filter you had installed, it may have a form of carbon in it for taste and odor removal. If the carbon in this type of filter breaks down, it’s able to enter the ice machine’s water system and and plug up components in the water circuit. It’s possible that while you’ve replaced your filter, there are still issues within the water circuit from the previous one, and that’s why it’s still not running properly. It would be best to have a trained ice machine technician inspect your ice machine’s water circuit and ensure all components are free of any obstructions.
Best of luck!
