E19 error: the unit indicates a low salt condition even when salt is present.

Safety: Disconnect power. Use care when reaching into the brine tank.

• Verify salt level: Confirm that there is adequate salt in the brine tank and that it is not bridged above the water level.
• Inspect salt float/sensor: Locate the salt level float or electronic sensor in the brine tank. Ensure it moves freely and is not buried in hardened salt.
• Clean sensor: Remove the sensor and clean off salt crusts with warm water. Avoid using sharp tools that could damage the sensor body.
• Check wiring: Follow the sensor cable to the control board and ensure it is intact and properly connected.
• Reset alarm: After cleaning and reconnection, reset the E19 alarm. If it returns despite correct salt level, replace the salt level sensor assembly.
