Display shows NO FLOW even when water is being used in the house

Safety: Close inlet/outlet valves and depressurize before removing the flow meter.

• Confirm plumbing: Verify that the house water is routed through the AFWFilters softener correctly and not bypassing the flow meter.
• Inspect flow meter: Remove the flow meter from the control valve. Check that the turbine spins freely when blown on or moved with a small tool. Clean out any debris or iron buildup.
• Check wiring: Inspect the sensor cable for cuts, abrasions, or loose connectors. Reseat the connector at the control board.
• Test after cleaning: Reinstall the flow meter, restore water, and run a faucet. The display should now show flow. If not, replace the flow meter assembly.
