Display indicates “No Regen” or similar message and the unit has not regenerated for an extended period.

Safety first: Ensure the system is not in BYPASS if you expect soft water.

Check bypass and flow:

• Verify the Kinetico bypass valve is in the SERVICE position.
• Open a faucet and confirm water is flowing through the softener (watch the meter display for flow).

Controller settings:

• Enter the programming mode and check for any regeneration inhibit or vacation mode settings. Disable them if not needed.
• Verify hardness and capacity settings are correct so the unit can schedule regenerations properly.

Manual regeneration:

• Initiate a manual regeneration cycle according to the manual.
• If the unit will not start regeneration or stops immediately, investigate for motor, valve, or sensor faults as indicated by any accompanying error codes.
