Display shows “Lo Salt” or “Low Salt” warning

Safety: No electrical or pressurized work is required for basic checks.

• Check actual salt level: Open the brine tank and visually confirm the salt level. If low, add the appropriate Culligan-approved water softener salt.
• Break salt bridges: If the top appears full but there is a hollow space underneath, gently push a broom handle down through the salt to break the bridge.
• Adjust sensor height: If your Culligan model has an adjustable salt level float or sensor, confirm it is set to the correct height per the manual.
• Clear the warning: Some models require acknowledging the Lo Salt message via the keypad. If the warning persists with adequate salt and a free-moving float, the sensor may be faulty.
