Possible Causes

Flow meter not registering flow, Regeneration mode set to time with long interval, Controller misprogrammed, Faulty flow sensor wiring

How to Fix / Troubleshooting

Safety first: Programming checks only; no plumbing work required initially.

  • Check regeneration mode: Confirm the unit is set to metered/demand mode if you expect usage-based regeneration.
  • Verify capacity and reserve: Ensure capacity is not set excessively high and that reserve is reasonable for your usage.
  • Flow test: Run a tap and watch the display for flow indication or decreasing remaining capacity. If there is no change, inspect and clean the flow meter, then replace if necessary.
  • Manual regeneration: Until the issue is resolved, trigger manual regenerations at appropriate intervals to maintain soft water.
