💡 Scotsman Light Pattern Guide
Slow Blue Flashing
Harvest verification or default harvest modes
Quick Blue Flashing
Manual harvest operations during freeze or harvest
Clean Indicator Blinking
Active cleaning cycle in progress
Note: If clean indicator stops blinking during cleaning, the cycle has completed and the system will perform drain cycles and reset the internal cleaning timer.
Code 3: No Water Error
Water sensors not detecting water - restart on water resupply type error
Good News: Code 3 is a "restart on water resupply" error, meaning the machine will automatically attempt to restart once adequate water supply is restored.
Most Common Causes
Dirty Water Sensors
Sensors contaminated with dirt, scale, or debris (Most Common)
Faulty Sensors
Sensors fail to detect proper water levels in reservoir
Wiring Issues
Damaged or loose connections, especially green wires to white plug
Step-by-Step Solutions
Clean Water Sensors (DIY Safe)
- • Remove sensors from housing
- • Clean thoroughly with descaling solution
- • Check all electrical connections are tight
- • Reinstall and test
Wiring Inspection (Professional)
- • Trace sensor wires completely
- • Check green wires to white plug connection
- • Test electrical continuity
- • Repair damaged wiring
Sensor Replacement (Professional)
- • Test sensor functionality with diagnostics
- • Replace faulty sensors if cleaning doesn't work
- • Calibrate new sensors
- • Verify proper operation
Code 2: Max Harvest Shutdown
Machine cannot complete harvest cycle within programmed time limit
Complex Mechanical Issue
Code 2 often involves seized or stuck mechanical components that require professional service for proper diagnosis and repair.
Common Causes
Seized Harvest Assist
Mechanism stuck in evaporator
Scale Buildup
Heavy scaling prevents ice release
Mechanical Obstruction
Physical blockage in harvest cycle
What Happens
• Ice starts forming normally
• Harvest cycle begins but can't complete
• Ice begins melting in evaporator
• Machine triggers Code 2 alarm
• System shuts down for protection
Professional Solutions
Harvest Assist Inspection
Free seized mechanism
Complete Descaling
