Display shows “Err 06” and the unit does not recognize salt level or brine tank status (on models with salt sensor).

Safety first: Unplug the controller before working near electrical connections. Wear gloves when handling salt.

Check the brine tank:

• Open the brine tank lid and inspect for a salt bridge (a hard crust of salt above an empty space). Tap the side of the tank with a rubber mallet; if it sounds hollow, a bridge is likely.
• Use a broom handle or similar tool to gently break up the salt bridge, being careful not to damage the brine well or float assembly.
• Ensure the float/brine well area is free of salt chunks and debris.

Inspect the sensor:

• Locate the salt level sensor (often mounted in the brine well or on the side of the tank).
• Disconnect the sensor wiring harness and inspect for corrosion or moisture. Dry and clean contacts if needed.
• Check that the sensor is mounted at the correct height and not bent or obstructed by salt.

Test and reset:

• Reconnect the sensor harness and restore power.
• Follow the controller instructions to clear the error or recalibrate the salt sensor if applicable.
• If Err 06 persists, the sensor is likely defective and should be replaced.
