Scotsman Ice Machine is Not Starting or Producing
A Scotsman commercial ice machine may not start up for various reasons. The most common issues that can cause Scotsman ice machines to fail to turn on include a faulty power supply, a defective bin control, or an inadequate amount of water in the reservoir. Under normal circumstances, the refrigerant charge is the least likely problem; don’t go there yet.
Let’s review some of the basics.
A transient issue may have arisen that caused a lockout. One potential issue is that the power supply may be completely cut off at a circuit breaker or fuse. Check to ensure that the power cord is properly plugged in and that there are no loose connections in the unit. A voltmeter and much caution are needed to verify this.
There is a saying in the service community that if an appliance is not working, reset it by turning off the power supply and then attempting to restart it.
If the machine is running, but the refrigeration system does not start, then there is no need to continue. A specially equipped and qualified service technician is required to investigate the refrigeration system issue.
Another possible issue is that the bin control component may be defective. If this is the case, replace it with a new one to restore the proper operation of the Scotsman ice machine. Consult the Scotsman factory service manual for the best procedure to verify this failure.
If the Scotsman ice machine still doesn’t start (or starts and is not making ice), it may be due to insufficient water in the reservoir.

A Scotsman commercial ice machine reservoir can run low on water for various reasons. These include
- Inadequate water level
- Slow water leaks,
- A broken float switch
- A restricted or defective water inlet valve
A Scotsman commercial ice machine can experience low water levels in the reservoir for various reasons. The inadequate filling is the most common cause, but slow water leaks and broken float switches can also contribute to low levels.
Ice machine maintenance deficiencies are a major issue with ice machine owners. Water filters can be a significant cause of Scotsman commercial ice machines experiencing low water levels in their reservoirs. Over time and without periodic replacement, the filter restricts, blocking the flow of water and restricting the amount of freshwater entering the reservoir. This issue can lead to low water levels and impurities being introduced into the system, resulting in Scotsman ice machines not starting up correctly.
In general, commercial ice machines can experience low production volume for a variety of reasons. The first symptom is that the Scotsman ice machine won’t start up properly, which may be due to a faulty power supply, a defective thermostat, or an inadequate amount of water in the reservoir. Possible causes include inadequate filling, slow water leaks, broken float switches, and clogged water filters, all leading to insufficient water levels in the machine’s reservoir. To help prevent this issue, it is essential to regularly check and replace any filters as needed and ensure adequate fresh, clean water is filling the ice machine’s storage tank. Contact a commercial ice machine specialist for assistance if you are still experiencing low production volume.
For any ice machine to make ice, it needs water. Water is the first ingredient in ice. Several issues can cause no water in a water trough, and we’ll cover the most common issues in this guide. Although some of these solutions may seem simple, starting with the fundamentals is essential.
Start with ensuring you have a water supply to the machine. Just because you have a water line connected does not mean water is available. Another piece of equipment may have been added to the main line that robs the ice machine of water. Another reason could be that the lines are clogged with debris due to maintenance work someplace in the building.
Next, check the water line filter to make sure it is clean. If the filter is clogged or restricted, it will not allow enough water into the machine, resulting in a low production rate. Smaller commercial ice machines typically have their integrated water filter that should be inspected regularly and replaced if needed.
To Summarize
For any ice machine to work including the Scotsman ice machine to make ice, it needs water. Several issues can cause no water in a water trough. Although some of these solutions may seem simple, starting with the basics is essential to ensure your commercial ice machine works optimally.
Start with ensuring you have a water supply to the machine. A water line (and hopefully a water filter) connection does not mean that water is always available. Another piece of equipment may have been added to the line, which has reduced the water flow to the ice machine. Also, check (at least) the following conditions that could reduce or completely cut off water flow.
- Restricted or plugged water filter
- NO water supply
- Restricted or defective water inlet valve or float
- Defective control board (least likely) that is not supplying water level information and prevents the startup from occurring.
Repairing a commercial ice machine can be expensive when parts are changed without the correct diagnosis. When the parts are not the reason for the ice machine not starting or producing ice, the situation becomes frustrating and economically harmful. Consider hiring a qualified and trained ice machine specialist to diagnose and install the needed parts when needed.
