Scotsman Ice Machine Error: 1 Flash, Freeze Time Retry (ELITE)
One flash on a Scotsman Prodigy ELITE or Prodigy Eclipse EH330/EH430 means a freeze cycle ran past the maximum freeze time and the controller is trying again. The machine is still working. Check that the water supply is open, clear the area around the condenser and call us if the flashing keeps repeating.
Medium: the machine keeps running, but repeated retries usually lead to a full shutdown.

What does Scotsman error code 1 flashes mean?
When a freeze cycle takes longer than the maximum time the controller allows, it does not shut down at once. It records the event, starts another cycle and shows a single flash on the code display. At this stage the machine is still trying to make ice, so staff may notice slow production, a longer wait between harvests, or a code flashing while the machine keeps working. The flash is an early warning that something is limiting the freeze. The manual lists a restricted water supply, filter or fill valve, a dirty condenser or hot kitchen that slows the freeze, scale on the evaporator and in the water trough, and an expansion valve or refrigerant charge that feeds the evaporator poorly. If these retries keep happening, the machine usually ends in a full shutdown with a steady 1, so catching the flashing early saves a stopped machine. A busy, hot kitchen is where this tends to show up first.
Affected models and control systems
This applies to Scotsman Prodigy ELITE (MC) cubers and Prodigy Eclipse EH330 and EH430 (C and D) remote cubers with the controller code display, per the Prodigy ELITE service manual of January 2022.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Code flashing once on the display
- Slower ice production
- Longer gaps between harvests
- Machine still running
Possible causes
Listed in Scotsman's documentation
- Restricted water supply, filter or fill valve
- Dirty condenser or hot kitchen slows the freeze
- Scale on the evaporator and in the water trough
- Expansion valve or refrigerant charge feeds the evaporator poorly
Other likely causes — what usually sits behind error code 1 flashes on this control. A technician confirms which one it is before any part is replaced.
- A condenser filter clogged with kitchen grease in a warm prep area
- A water line kinked behind the machine after it was slid back for cleaning
Safe checks before calling for service
- Check that the water supply valve is open and the line is not kinked.
- Clear boxes and clutter from around the condenser air intake.
- Note how often the flashing returns and write down the model number from the data plate.
- Call us if it repeats, since a retry that keeps repeating usually ends in a full shutdown.
How a technician diagnoses error code 1 flashes
- Read the code history and see how often one-flash retries occurred.
- Verify water supply, filter and fill valve flow.
- Inspect the condenser, fan and ambient temperature.
- Look for scale on the evaporator and in the trough.
- Check refrigerant pressures and expansion valve behavior, and replace parts only after the tests.
- Checking refrigerant pressures requires licensed gauges and handling of regulated refrigerant.
- The compressor and fan circuits run on 208-240 V behind the panels.
How error code 1 flashes differs from similar codes
One flash means the controller is retrying and the machine still runs, while a steady 1 means it has shut down. On Prodigy Plus flake and nugget machines, one flash refers to ice not being sensed.

Do I need to stop using the machine?
It is still working, so it may continue, but a repeating flash is a warning to get it checked.
What happens if I ignore it?
Repeated retries usually end with the machine shutting down and showing a steady 1.
Does a flash mean the same as a steady 1?
No, the flash is the retry stage, while the steady 1 is the shutdown.
