Display shows E02 and unit does not draw brine during regeneration

Safety first: Unplug the softener and place the system in bypass before disassembling any water-carrying parts. Relieve pressure by opening a nearby soft water faucet.

• Check brine level: Ensure there is adequate water in the brine tank (typically 6–12 inches above the grid plate). If the tank is dry, refill to the recommended level and restart a regeneration.
• Inspect brine line: Follow the brine tube from the brine tank to the Watersoft control valve. Look for kinks, cracks, or blockages. Remove the brine line at the valve and blow through it; it should be free-flowing.
• Clean venturi/injector: Remove the venturi/injector housing from the Watersoft valve head (usually held by screws or a cap). Disassemble carefully and soak the injector, nozzle, and screens in white vinegar to dissolve iron or scale. Rinse thoroughly and reassemble in the correct order.
• Check brine valve: Inspect the brine valve assembly in the control head for salt buildup or debris preventing movement. Clean or replace the brine valve and seals if worn or swollen.
• Test drive motor: With the cover off and power restored, initiate a manual regeneration and observe whether the cam/rotor moves into brine draw position. If the motor does not run or stalls, the Watersoft drive motor may need replacement.

If E02 persists after cleaning and verifying flow, a technician should test the control board outputs to the motor and brine valve.
