Possible Causes

Incorrect time or regeneration time set, Regeneration mode set to metered instead of time, Power loss resetting clock, Controller in vacation/hold mode

How to Fix / Troubleshooting

Safety first: No plumbing work is required for this check.

  • Verify current time: Enter the time-setting menu and correct the current time and day.
  • Check regeneration mode: Confirm whether the unit is set to time-based or metered regeneration and adjust according to your needs.
  • Review regeneration time: Ensure the regeneration start time is set to a future time (usually 2:00 AM) and not disabled.
  • Check for vacation mode: Some Water2Buy controllers have a vacation or hold mode. Disable it if active.
  • Monitor next cycle: After adjustments, observe whether the next scheduled regeneration occurs. If not, the control board may need replacement.
