What Does Error 5 Mean?

The Scotsman Ice ice maker error code 5 indicates a water fill failure due to a malfunctioning sump temperature sensor. This error typically results in a blinking display and halts ice production. The temperature sensor fault in the sump circuit affects accurate temperature sensing, leading to operational issues.

Common Symptoms:

  • Ice maker displays error code 5 and may shut down or stop producing ice
  • Temperature sensor-related faults affecting proper sensing of temperature in the water/sump area

Possible Causes

  • Sump temperature sensor failure or malfunctions (thermistor/temperature probe fault) (medium)

How to Fix Error 5

DIY Fix Basic checks and reset

  1. Turn off and unplug the ice maker for 5–10 minutes to reset control electronics.
  2. Ensure the error reoccurs after power-up to confirm persistence.
  3. Check for obvious loose wiring harnesses in accessible areas if safe to do so.

Technician Only Test and replace sump temperature sensor

  1. Disconnect power and gain safe access to the controller area and sump sensor location.
  2. Use an ohmmeter or appropriate temperature measurement tool to test sensor resistance versus expected values from the service manual.
  3. Inspect wiring and connections for damage or corrosion between the sensor and controller.
  4. Replace the sump temperature sensor if out of specification or visibly faulty.
  5. Verify operation and clear the error code after replacement.

Parts needed: Sump temperature sensor (thermistor/probe), Wiring harness/connectors as needed
