Water softener display shows flow even when no water is being used in the house.

Safety first: Unplug the unit before disconnecting sensor wiring.

• Step 1 – Confirm no actual usage: Shut off all fixtures and check for any running toilets or leaks.
• Step 2 – Inspect turbine sensor wiring: Check the harness from the turbine sensor to the control board for damage or moisture.
• Step 3 – Disconnect sensor: With power off, unplug the turbine sensor from the control board. Restore power and see if the flow indication stops. If it does, the sensor is likely faulty.
• Step 4 – Replace sensor: Install a new GE turbine sensor if it is causing false pulses.
• Step 5 – Replace control board: If false flow persists with the sensor disconnected, the GE electronic control board input is likely defective and should be replaced.
