E02 displayed and unit does not draw brine during regeneration

Safety: Disconnect power and close the inlet valve. Wear gloves and eye protection when handling salty water.

• Check brine level: Ensure there is sufficient water in the brine tank. If the tank is completely dry, add water per Aqmos instructions and restart a regeneration.
• Inspect brine line: Follow the small tube from the brine tank to the control head. Look for kinks, cracks, or loose push-fit connectors. Reseat or replace tubing as needed.
• Clean venturi/injector: Remove the injector/venturi assembly from the Aqmos valve head (usually under a cap). Disassemble and soak parts in warm water with a little vinegar to dissolve scale. Rinse thoroughly and reassemble.
• Check brine valve: Manually move the brine valve (if accessible) to ensure it is not stuck. If the valve does not move freely or leaks, replace the brine valve cartridge.
• Test regeneration: Restore water and power, then start a manual regeneration and observe whether brine is drawn from the tank. If E02 persists, the control valve assembly may need professional service.
