Err12 displayed, unit reports low salt even when tank is full

Safety: Unplug the softener. Use caution when breaking salt bridges to avoid damaging the tank.

• 1. Check for salt bridge: Push a broom handle or similar tool straight down into the salt. If you feel a hollow space before reaching the bottom, a salt bridge is present. Carefully break it up so salt falls to the bottom.
• 2. Verify sensor position: Ensure the salt level sensor is installed at the correct height per the North Star manual. Adjust if it is mounted too high above the normal salt level.
• 3. Clean sensor: Remove and clean the sensor of any heavy buildup. Rinse with warm water and reinstall.
• 4. Reset alarm: Restore power and clear the low salt alarm through the control menu. Monitor for recurrence.
• 5. Replace sensor: If the alarm returns despite proper salt level and a clean, correctly positioned sensor, replace the salt level sensor.
