E14 error and the unit cannot detect salt level (on models with electronic salt sensor)

Safety first: Disconnect power before handling any sensor wiring. Wear gloves when working inside the brine tank.

• Locate salt sensor: On Nobel models with this feature, the salt level sensor is usually mounted in the brine well or side of the brine tank with a cable leading to the control head.
• Check connection: Ensure the sensor plug is firmly connected to the control board. Inspect the cable for cuts or crushed sections.
• Inspect and clean probe: Remove the sensor from the tank. If it is coated with heavy salt or rust, rinse it in warm water and gently scrub with a soft brush. Do not bend or scratch the probe surfaces.
• Break salt bridge: If a hard crust (salt bridge) has formed above the sensor, carefully break it with a broom handle or similar tool, taking care not to damage the tank. Remove loose chunks of salt.
• Reset alarm: Reinstall the sensor, restore power, and clear the E14 alarm via the control panel. Verify that the displayed salt level is reasonable.

If E14 persists with a clean, properly connected sensor, the sensor or control board input may be defective and require replacement.
