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
- Turn off and unplug the ice maker for 5–10 minutes to reset control electronics.
- Ensure the error reoccurs after power-up to confirm persistence.
- Check for obvious loose wiring harnesses in accessible areas if safe to do so.
Technician Only Test and replace sump temperature sensor
- Disconnect power and gain safe access to the controller area and sump sensor location.
- Use an ohmmeter or appropriate temperature measurement tool to test sensor resistance versus expected values from the service manual.
- Inspect wiring and connections for damage or corrosion between the sensor and controller.
- Replace the sump temperature sensor if out of specification or visibly faulty.
- Verify operation and clear the error code after replacement.
Parts needed: Sump temperature sensor (thermistor/probe), Wiring harness/connectors as needed
- If the error persists after sensor testing and replacement
- If there are signs of wiring harness damage, moisture ingress, or other components failing
- If you are not experienced with electrical appliance repair
