Display shows “Err 06” and unit does not detect salt level correctly (salt alarm even when tank is full)

Safety: Unplug the unit before working inside the brine tank.

• Check for salt bridging: Open the brine tank lid. Use a broom handle or plastic rod to gently push down on the salt. If it feels hollow underneath, break up the salt bridge so it collapses into the water.
• Inspect sensor: Locate the Ecowater salt level sensor (float or optical probe) in the brine well. Ensure it moves freely and is not buried in hardened salt.
• Clean sensor: Remove the sensor carefully and rinse with warm water to remove salt crust and sludge. Do not use abrasive tools.
• Check wiring: Follow the sensor cable to the control head. Reseat the connector and inspect for cuts or crushed insulation.
• Test operation: Reinstall the sensor, restore power, and run the salt level test (if available in the menu). If Err 06 remains, replace the salt level sensor assembly.
