9 researched codes and status messages; 0 require model-specific verification. A code alone is not proof of a failed component.
POWER greenNormal status
Ice maker is on.
What to do: Check the selected mode and actual operating condition against the model owner guide. Record any symptom that persists after the normal condition ends.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Owner-described state or setting. Descriptive LED / behavior labels are not asserted to be literal text on the display.
Manufacturer / technical referenceICE blue steadyNormal status
Ice-making indication.
What to do: Check the selected mode and actual operating condition against the model owner guide. Record any symptom that persists after the normal condition ends.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Owner-described state or setting. Descriptive LED / behavior labels are not asserted to be literal text on the display.
Manufacturer / technical referenceDELAY 2 flashingNormal status
2-hour manual production delay is selected.
What to do: Check the selected mode and actual operating condition against the model owner guide. Record any symptom that persists after the normal condition ends.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Delay is a selected operating state. Auto Delay, if selected separately, can repeat daily; not a component error.
Manufacturer / technical referenceDELAY 4 flashingNormal status
4-hour manual production delay is selected.
What to do: Check the selected mode and actual operating condition against the model owner guide. Record any symptom that persists after the normal condition ends.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Delay is a selected operating state. Auto Delay, if selected separately, can repeat daily; not a component error.
Manufacturer / technical referenceDELAY 8 flashingNormal status
8-hour manual production delay is selected.
What to do: Check the selected mode and actual operating condition against the model owner guide. Record any symptom that persists after the normal condition ends.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Delay is a selected operating state. Auto Delay, if selected separately, can repeat daily; not a component error.
Manufacturer / technical referenceCLEAN green steadyNormal status
Cleaning cycle is running.
What to do: Check the selected mode and actual operating condition against the model owner guide. Record any symptom that persists after the normal condition ends.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Owner-described state or setting. Descriptive LED / behavior labels are not asserted to be literal text on the display.
Manufacturer / technical referenceCLEAN flashingMaintenance
Cleaning sequence requests cleaner / sanitizer.
What to do: Follow the exact model cleaning / filter instructions and use approved supplies. A reminder alone does not establish a component fault.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Documented cleaning-sequence prompt; use the exact owner procedure and approved product.
Manufacturer / technical referenceREPLACE FILTER redMaintenance
Water-filter replacement reminder.
What to do: Follow the exact model cleaning / filter instructions and use approved supplies. A reminder alone does not establish a component fault.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Matching guide uses 8,000-cycle reminder; not an automatic failed-filter diagnosis.
Manufacturer / technical referenceBlue ICE light flashing + not runningProtection
Automatic protected stop: two consecutive maximum freeze/harvest cycles OR 120 continuous cycles without bin-switch satisfaction.
What to do: Record full model/suffix, control revision, complete code / LED cadence, mode and sequence. Use the matching owner guide. Persistent faults require qualified service; the indication does not prove one part has failed.
Applies to: Sub-Zero UC-15I / UC-15IP standalone undercounter ice maker; matching SZ1 guide generation
Scope: Specific not-running context. Source gives 55-minute maximum cycles and approximately two days for 120 cycles; no unique failed component is established.
Manufacturer / technical referenceNo matching records. Check the model, display characters or beep/LED pattern and the matching owner guide.
