Softener does not regenerate at all; water remains hard even after expected regeneration time, and no error code is shown.

Safety: Keep covers closed while adjusting settings; no internal electrical work is required.

• Check bypass: Verify that the Hansgrohe bypass valve is in the 'service' position, not bypass.
• Verify power: Ensure the power adapter is plugged in and the outlet is live. Replace the adapter if the control display is dim or intermittent.
• Set time and schedule: Confirm the current time and regeneration time are correctly programmed. Ensure the unit is set to meter-initiated or time-initiated regeneration as desired.
• Test meter: Run water in the house and check that the display shows flow or usage. If not, inspect and clean the flow sensor.
• Manual regeneration: Start a manual regeneration from the control panel. If it runs correctly, monitor whether automatic cycles resume. If not, the control board may need replacement.
