Resetting a Hoshizaki ice machine may sound like a simple task, but there’s much more to it if you want to do it right. Businesses like restaurants, hotels, or convenience stores rely on ice machines every day. When something goes wrong, it’s not just inconvenient—it can also mean lost sales or unsatisfied customers.
Knowing how to reset a Hoshizaki ice machine quickly and correctly can save you time, money, and frustration.
Many owners and staff think pressing the reset button is all it takes. However, a true reset involves checking for error codes, understanding why the machine needs a reset, and following proper safety steps. This guide covers every aspect you need to know, from basic resets to troubleshooting deeper issues.
You’ll also find tables comparing different Hoshizaki models and error codes, plus practical tips from the field. Whether you’re new to ice machines or a seasoned pro, you’ll gain insights that most beginners overlook.
Why Hoshizaki Ice Machines Need Resetting
All ice machines, including Hoshizaki, occasionally need a reset. This is not just about fixing a minor glitch. A reset can help clear error codes, restart the computer board, or reinitialize sensors. Sometimes, after a power outage, a cleaning cycle, or a filter change, the machine may not start properly until you reset it.
For example, if the machine detects a water supply problem, it may lock itself to prevent damage. After fixing the issue, you must reset the ice machine to clear the alert. Understanding the reason behind the reset helps you avoid repeating the same problem.
Some common reasons for resetting a Hoshizaki ice machine include:
- Power interruptions
- Error codes or flashing lights
- After maintenance or cleaning
- Water filter replacement
- Software updates or control board issues
Knowing the root cause is essential. If you only reset the machine without fixing the underlying problem, the issue will return, sometimes worse than before.
Another point to remember is that frequent resets can point to a bigger, hidden problem. For instance, if your ice machine needs resetting every few days, it could mean there’s a persistent issue like inconsistent water pressure, a worn-out sensor, or unstable electrical supply.
Many beginners miss this pattern and simply keep resetting, which delays proper repairs and can end up damaging the machine further. It’s always better to investigate why the reset is needed instead of seeing it as a routine step.
Understanding Hoshizaki Error Codes
Before resetting, always check for error codes. Hoshizaki ice machines use a series of blinking lights or digital displays to indicate specific problems. Each code points to a different issue, from water shortage to temperature errors.
Here’s a comparison of some common error codes and their meanings:
| Error Code | Meaning | Possible Cause | Reset Needed? |
|---|---|---|---|
| 1 Flash | High Temperature | Dirty condenser or blocked airflow | Yes |
| 2 Flashes | Long Freeze Cycle | Low refrigerant, dirty evaporator | Yes |
| 3 Flashes | Long Harvest Cycle | Faulty float switch or water supply | Yes |
| 4 Flashes | High Pressure | Blocked condenser or fan issue | Yes |
| Continuous | Board Error | Control board malfunction | Yes |
Many beginners miss the importance of these error codes. They often rush to reset the machine without checking what the code means. Always write down or photograph the error code before resetting. This helps if you need to call for service later.
One extra detail: some Hoshizaki models will display a combination of flashes or even show numbers on a digital display. For example, if you see a display like “E2” or “F3,” these are also error indicators, and the manual will tell you exactly what they mean. Don’t ignore these codes—sometimes a simple fix like cleaning a sensor or unclogging a filter is all you need, but you have to know what the code is telling you.
It’s also a good habit to keep a printed or digital copy of your machine’s error code chart nearby. This way, staff can quickly identify problems and avoid confusion, especially if there’s a language barrier or different shifts working on the machine.
Safety Steps Before Resetting
Working with commercial ice machines involves water, electricity, and sometimes sharp parts. Safety must always come first. Never reset a Hoshizaki ice machine without taking these basic steps:
- Unplug the machine or turn off the circuit breaker before opening any panels.
- Wear gloves and, if possible, safety glasses.
- Read the manual for your exact Hoshizaki model. Not all models have the reset button in the same place.
- Clear the area of any water spills to avoid slips or electrical shocks.
Neglecting safety steps is a common mistake, especially during busy shifts. Taking one extra minute for safety can prevent injuries and damage.
Another detail many users miss: after unplugging the machine, wait at least 30 seconds before touching internal parts. Some components can hold electrical charge even after the power is off. Also, if you’re working in a kitchen or bar, let coworkers know you’re working on the ice machine, so no one accidentally turns the power back on.
If you notice any strange smells (like burning or melting plastic) or see sparks while opening the machine, stop immediately and call a technician. These are warning signs of electrical faults that should never be ignored.
Identifying Your Hoshizaki Model
Hoshizaki makes many types of ice machines—modular, undercounter, and dispenser models. The reset process can vary depending on the model. Check the data plate, usually found on the side or back of the unit, for the model number.
Here’s a quick comparison of popular Hoshizaki models and their reset procedures:
| Model Type | Reset Button Location | Notes |
|---|---|---|
| Cuber (KM Series) | Behind front panel, near control board | Often requires panel removal |
| Flaker (F Series) | Inside service compartment | Smaller button, sometimes labeled “Reset” |
| Undercounter (AM Series) | Side panel or near power cord | May require tool to access |
| Dispenser (DFM Series) | Control interface | Some use digital reset through menu |
If you’re unsure of your model, search the serial number on the Hoshizaki website or consult your manual. This avoids confusion, especially if you’re working with several machines.
A handy tip: take a clear photo of your machine’s data plate and keep it on your phone. This makes it quick to find the right manual or order the right parts, especially during a service call. For locations with multiple machines, labeling each unit with its model and basic reset steps can save a lot of time for staff.

Step-by-step: How To Reset A Hoshizaki Ice Machine
Resetting your ice machine is not just one step. Here’s a detailed, step-by-step guide that applies to most Hoshizaki models. Adjust as needed for your specific unit.
1. Diagnose The Problem
Before hitting the reset button, understand why you’re resetting. Check for:
- Blinking lights or error codes (see the error code table above)
- Unusual noises or leaks
- Visible blockages or dirt
Fix any obvious issues first. For example, if the filter is clogged, replace it before resetting.
If you notice ice build-up inside or water not draining, deal with these problems first. Removing obstructions or cleaning a blocked line can sometimes fix the error without needing a reset.
2. Turn Off The Power
Find the power switch, usually on the front or side panel. Turn the ice machine OFF. For extra safety, unplug the unit or switch off the breaker.
It’s a good habit to wait 30 seconds after turning the power off. This allows the machine’s control board to fully reset and helps avoid false restarts.
3. Access The Reset Button
Remove the front or side panel carefully. Use a screwdriver if needed. Locate the reset button—it’s often a small red or black button near the control board. Some models have it labeled clearly, while others may require checking the manual.
If you can’t find the button, look for a small hole or slot labeled “Reset. ” Some undercounter units hide the button inside a compartment to prevent accidental presses.
4. Hold The Reset Button
Press and hold the reset button for about 5-10 seconds. On digital models, you may need to navigate the menu and select “Reset. ” Release the button when the indicator lights change or you hear a beep.
If you don’t see or hear any change, repeat the step, but don’t press too hard. Forcing the button can damage the control board. On some models, you may need to hold the button until a specific light flashes or until a countdown finishes on the display—always check your manual for details.
5. Restore Power
Plug the machine back in or turn on the breaker. Switch the machine to ON. Wait for the unit to cycle and listen for normal operation sounds.
Give the machine a minute to start up. Some Hoshizaki machines do a short self-test before resuming normal ice production.
6. Monitor For Errors
Watch the machine for the next 10-15 minutes. Check if error codes return. If the same error appears, the underlying issue isn’t fixed. If the machine runs smoothly, you’ve completed the reset.
Pay attention to any new noises, drips, or smells. These may be early signs of a problem that the reset didn’t fix.
7. Make Ice Test
Once reset, let the machine complete one full ice production cycle. Check the first batch of ice for proper size, clarity, and shape. Discard the first batch, as it may contain cleaning solution or residue.
If the ice looks odd—too small, soft, or cloudy—investigate before serving to customers. Sometimes, a reset triggers a cleaning mode or uses leftover water, which can affect ice quality.
8. Document The Reset
Write down the date, time, and reason for the reset in your maintenance log. This helps track recurring issues and informs future repairs.
You can also include photos or short notes about what you found (like “error code 3 flashes, replaced filter, reset successful”). This record makes troubleshooting much easier over time, especially if multiple staff members use the machine.
Common Mistakes To Avoid
Many users make errors that can damage the machine or fail to fix the problem. Here are mistakes to avoid:
- Skipping the error code check – Always note the code before resetting.
- Ignoring safety steps – Never open panels with power on.
- Resetting too often – Repeated resets can mask deeper issues.
- Forgetting to clean components – Dirt is a common cause of errors.
- Not updating maintenance logs – Good records help spot patterns over time.
Resetting should be a last step after addressing any real problems.
Another mistake: using the wrong tools or too much force when opening panels. Hoshizaki machines use precise parts—damaging a panel can make future servicing harder and more expensive.
Also, don’t guess at the cause. If you’re unsure, take photos of the situation and ask for help. Guessing can lead to more downtime or even void your warranty.

How Resetting Differs For Hoshizaki Vs. Other Brands
Some ice machines, like Scotsman or Manitowoc, use a different reset process. Hoshizaki models often require holding the reset button longer or cycling the power differently. Here’s a quick comparison:
| Brand | Reset Method | Unique Steps |
|---|---|---|
| Hoshizaki | Reset button + power cycle | Error code check, panel removal often required |
| Scotsman | Press and hold service button | Shorter hold time; usually front panel access |
| Manitowoc | Push “On/Off” + “Clean” | May need to wait for cleaning cycle to finish |
If you’re used to other brands, don’t assume the process is the same. Read the Hoshizaki manual for your exact model.
As an extra tip, if you manage a location with several brands, create a quick “cheat sheet” for staff with the basic reset steps for each brand. This prevents mistakes and helps new staff get up to speed quickly.
When To Call A Professional
Not every problem can be solved with a reset. If you notice any of these situations, call a certified technician:
- Error codes repeat after several resets
- Water leaks or electrical smells
- Unusual loud noises or vibrations
- Ice quality is poor after reset (soft, cloudy, or misshapen ice)
- No power to the machine after reset
Attempting to repair electrical or refrigerant issues without training can be dangerous and may void your warranty.
One more sign: if your machine is still under warranty or part of a service contract, always call for help rather than risk a DIY repair. Keep your paperwork handy so you can get service quickly.
Preventing Future Problems
Resetting is often a symptom of a bigger issue. Here’s how to reduce future resets:
- Clean the machine regularly – Dirt and scale are the top causes of errors.
- Replace filters on schedule – Blocked filters lead to water errors.
- Inspect water lines and connections monthly.
- Keep condenser coils free of dust and obstructions.
- Log every reset and service to spot patterns.
- Train staff on correct use and cleaning procedures.
- Install surge protectors to prevent electrical issues.
Proactive care means fewer breakdowns and less downtime.
Another best practice: schedule a deep clean and inspection at least once every six months, even if you haven’t had errors. This catches problems early and can extend the life of your machine. Also, always use the correct replacement parts. Generic filters or components may not fit perfectly and can cause leaks or errors.
Extra Tips Most Beginners Miss
- The first batch of ice after a reset should always be discarded. This removes any debris loosened during maintenance.
- If your Hoshizaki ice machine uses a water filter, resetting may also require you to reset the filter timer, usually by holding a button for several seconds.
- Don’t forget the ambient temperature. Ice machines perform best in rooms between 45°F and 90°F (7°C – 32°C). High temperatures can trigger errors that a reset won’t fix.
- Keep a photo log of error codes with your smartphone. This makes it easier to explain problems to a technician.
- Use only manufacturer-approved cleaners and descalers. Off-brand chemicals can harm sensors and void your warranty.
Another expert tip: if your business has frequent power outages or voltage fluctuations, install a voltage stabilizer. Power surges are a hidden cause of control board errors, and a stabilizer can prevent many resets.
If your machine is used heavily (like in a busy restaurant), consider posting a quick checklist near the unit. This can include “Check for error codes,” “Clean water filter,” and “Log resets. ” Staff can quickly run through the list before calling for help, saving time and money.
