What Does Error 3 Mean?

The Scotsman Ice ice maker error 3 indicates a malfunction in the water level sensor, leading to issues with water filling or ice production. This error may cause the machine to halt ice production, display the error code, or pause the ice-making cycle due to insufficient water detection or slow water fill rates. Common causes include clogs in the water line, issues with the water inlet valve, or sensor contamination.

Common Symptoms:

  • Machine stops ice production
  • Error 3 displayed or indicated by lights
  • Ice maker shuts off or pauses cycle
  • Apparent lack of water reaching the ice making system

Possible Causes

  • Insufficient water detected in reservoir (no water present) (medium)
  • Slow water fill due to inlet issues (valve, filter, line) (medium)
  • Water sensor contamination or malfunction (low)

How to Fix Error 3

DIY Fix Check water supply and flow

  1. Ensure the water supply valve to the ice maker is fully open
  2. Inspect the water line for kinks, clogs, or frozen sections
  3. If present, check and replace water filters if clogged
  4. Verify incoming water pressure meets unit requirements

Technician Only Inspect and service inlet components and sensors

  1. Disconnect power and water to the machine
  2. Inspect the water inlet valve for obstructions or failure; replace if necessary
  3. Test and replace water level sensors if cleaning does not restore proper detection
  4. Check wiring connections to water sensor and inlet valve for damage or loose connections

Parts needed: water inlet valve, water level sensor(s), wiring connectors

🛑 When to Call a Pro:
  • If water pressure and supply are confirmed but error persists
  • If replacement of valve or sensors does not clear error
  • If internal electronic faults are suspected
