Softener never regenerates, even after long periods of water use

Safety first: No internal disassembly required for basic checks.

• Check regeneration mode: Ensure the Nobel control is set to metered or time‑clock mode, not manual‑only. Adjust in the installer menu.
• Verify flow registration: Run water at a tap and confirm that the display shows flow or that the usage counter increases. If not, troubleshoot the flow meter.
• Set day override: Configure a maximum number of days between regenerations (e.g., 7 days) so the unit will regenerate even with low usage.
• Manual regeneration: Perform a manual regeneration to restore softening capacity while you diagnose the automatic trigger issue.
