Scotsman Ice Machine Troubleshooting Guide
Scotsman is known for reliable ice machines, clean ice production, and innovation in ice-making technology. It designs, engineers, and assembles all its ice-making equipment in the United States and offers a large catalog of over 100 ice machine models and a large support network, providing some of the most user-friendly ice machines on the market.
Like any appliance, Scotsman machines can experience breakdowns and mechanical issues over time or from improper use. This article will help ensure your Scotsman machine works properly, guiding you through essential troubleshooting steps and cleaning instructions.
How To Identify Issues
Common ice machine problems include inconsistent ice output, water leakage under the machine, and rattling noises. Scotsman ice makers often display error codes when an internal system fails, directing users to the affected part.
Understanding Scotsman Error Codes

Most models include a controller with four indicator lights, a code display, and several push buttons. Some models have component lights that turn on when each component is in use. The controller indicator lights cover the following:
- Power: On when there is power to the controller
- Status: On during ice-making mode
- Water: On and blinking when there is no water
- Descale & Sanitize: Indicates the machine is due for cleaning
Most Scotsman error codes appear on a seven-section display located behind the front panel. The following are common error or status codes you'll find on Scotsman ice dispensers, cubers, and nugget or flake makers:

Advanced Diagnostic Technology
Scotsman Prodigy machines can accommodate Smart-Board or Vari-Smart devices for enhanced diagnostics and control over ice level. These items can be field installed with an LCD display that shows details like time and date, water temperature, status messages, and timestamps for errors events.
Prodigy Elite® Ice Machines can connect to mobile devices via Bluetooth using the Icelinq® app, which provides unit information, cleaning steps, and troubleshooting support with real-time error notifications.
Troubleshoot Common Issues
Scotsman Ice Machine Not Making Ice
If your machine stops or drastically slows ice production, monitor the error code display or indicator lights to help identify the problem. Refer to your owner's manual for specific guidance. Scotsman ice machines may shut down automatically due to several reasons:
- Lack of water
- Overloaded compressor or auger motor
- High discharge pressure
- Low refrigeration system pressure
- High ambient or water temperature
Follow these steps to find or rule out potential issues:
- Confirm power and water supply
- Check water filters, ice thickness settings, and temperature settings
- Clean condenser coils
- Inspect internal components for damage
Dealing with Leaks
If your Scotsman machine is leaking, unplug it and inspect around and underneath the unit to locate the source. Common culprits include clogged drains, worn gaskets, and improperly sealed doors that can lead to condensation buildup.
To avoid recurring leaks, perform regular preventive maintenance such as descaling the bin and cleaning your drain tubes. You also need to provide the correct water connection with a filter.
“People think hooking up an ice machine is like a garden hose and extension cord, but it’s not," said a Scotsman representative. "Water pressure, drain requirements, and power all need to be right.”
Rattling Compressor
If your compressor is running and producing ice but makes excessive noise, check the compressor mounting bolts and connecting tubes to ensure they are secured properly. If they appear intact, you'll likely need to request service and may have to change your compressor.
How to Reset a Scotsman Ice Machine
If you're dealing with minor glitches or errors, sometimes simply resetting the Scotsman machine will solve the issue.
Scotsman Ice Maker Reset Button Location
Most Scotsman Prodigy ice machines have on and off buttons on their front panel, while HID ice dispensers require removing the front panel to access the reset button. It's best to access the control panel on any ice machine you want to reset to verify there are no error codes. If your ice machine is in the middle of producing ice, it may need to finish the cycle before the reset takes effect.
Reset Steps
To manually reset the machine:
- Open the switch door
- Push and release the red "Off" button
- Push and release the green "On" button
On an initial startup, it's common for the machine to give a flashing "F" code, which means the freeze cycle is pending. This occurs because it's running through a self-check to make sure all systems are operational.
To shut the machine off completely during a cycle, push and hold the "Off" button for 3 seconds or until the machine stops.
How to Clean a Scotsman Ice Machine
Even the most reliable ice machines need regular cleaning. Scotsman machines should be descaled and sanitized at least once every six months. The following steps outline general cleaning procedures for most standard Scotsman Ice Machines.
- Power off the unit and let any remaining ice dispense into the bin
- Disconnect the water tube and drain any water
- Use Scotsman-approved cleaner to fill the reservoir
- Run cleaning cycle once with descaling solution and again with sanitizer according to user manual
- Remove and soak ice-contact components in descaling fluid followed by sanitizing solution
- Rinse all parts thoroughly and reassemble
To clean a Scotsman SCN60 and other specialty models, follow the directions included in your user manual, as they vary depending on each model. Cleaning Scotsman nugget ice makers also involves checking the auger drive, but newer models have a maintenance-free bearing that doesn't require greasing.

Scotsman Ice Machine Cleaner Substitutes
When it comes to maintaining ice machines, the Scotsman representative states, "The biggest mistake is people just not cleaning the machine. The second biggest? Using the wrong cleaner or too much of it."
Scotsman recommends using the specified amount of their branded descaling and sanitizing solutions. Food-grade cleaners designed for ice machines also work.
Avoid using vinegar or overly acidic cleaners that won't correctly clean the interior and may harm internal materials. "Ice is food," the representative said. "You need to use food-grade sanitizer and the right cleaner."
Maintaining Your Scotsman Ice Machine
Keeping up with regular cleaning is key to long-term performance. Alongside cleaning and sanitizing the bin, operators should clean ice-making components, rinse the reusable filter, and wipe down condenser coils. Other components that need regular cleaning or periodic replacement include the water filter, water probe, ice bin sensor, and bearings for older models. Make sure you consistently maintain a clean environment around the ice maker to inhibit mold and slime buildup.
When to Contact a Professional
If you're uncomfortable performing any repairs or maintenance procedures, call for professional help. Technicians are also trained to fix recurring leaks, failed resets, or unresponsive machines. More complex projects, like cleaning augers or condenser fins, should also be handled by an experienced technician.
Keep Your Scotsman Running Smoothly
Though Scotsman ice machines are complex appliances, each comes with a user manual outlining straightforward cleaning, maintenance, and troubleshooting steps to help operators ensure a long running time. If your machine has an issue, the direct error codes will help clarify the issue, and you can call for professional assistance. Scotsman also provides instructional videos and helpful resources on diagnosing and cleaning each model.
