E03 error and the softener stops mid-cycle, often during brine draw

Safety: Unplug the Foridra softener before opening the brine tank or valve head. Wear gloves when handling salty brine.

• Check brine level: Ensure there is adequate water in the brine tank (typically 4–8 inches above the grid plate). If completely dry, the unit cannot draw brine; add water per the manual and allow salt to dissolve.
• Inspect brine line: Follow the small-diameter brine tube from the Foridra valve head to the brine well. Look for cracks, loose push-fit connectors, or kinks. Reseat or replace tubing as needed.
• Clean brine injector: Remove the injector assembly from the Foridra control valve (usually under a small cover). Soak in warm vinegar to remove iron and scale, then rinse and reinstall.
• Check brine float: Open the brine well (the inner tube in the salt tank). Move the float assembly up and down; it should move freely. Clean any salt crust or sludge and ensure the air check ball at the bottom is not stuck.
• Run a manual brine draw test: With the unit powered, start a manual regeneration and advance to brine draw. Observe if the brine level drops. If not, and all lines are clear, the internal valve rotor or seals may be worn.
