Possible Causes
Flow meter not registering usage, Regeneration mode set to manual, Control board logic fault
How to Fix / Troubleshooting
Safety: Unplug the unit before opening the control housing.
Steps:
- Check programming mode: Ensure the unit is set to demand-initiated or timed regeneration, not manual-only mode.
- Verify flow registration: Run water and confirm the display shows flow or usage increments. If not, inspect the flow meter.
- Test day-override: If using a day-override, confirm the override interval is not set to 0 or disabled.
Resolution: Replace the turbine flow meter assembly if it does not register flow. If the meter is good and programming is correct, replace the electronic control board.
