Display shows E02 and the unit does not draw brine during regeneration

Safety first: Disconnect power and place the softener in bypass. Depressurise by opening a nearby tap before opening the valve head.

• Check brine level: Remove the brine tank lid. Ensure there is water in the bottom of the brine tank; a completely dry tank can indicate no refill or suction issues.
• Inspect brine line: Follow the small brine tube from the valve head to the brine well. Check for kinks, blockages, or damage. Straighten or replace if necessary.
• Clean venturi/injector: On Aqua Dial valves, the injector/venturi is usually under a small cover on the valve head. Remove the cover screws, carefully lift out the injector and nozzle, and soak them in warm water with a little vinegar to dissolve scale. Use a soft brush or toothpick (never metal) to clear the orifices. Rinse and reinstall.
• Check brine safety float: Lift the brine well cover and move the float up and down. It should move freely. If it is stuck or heavily scaled, clean it or replace the float assembly.
• Reassemble and test: Refit all parts, restore water and power, then start a manual regeneration. Observe whether brine is drawn from the tank during the brine draw stage.
