Display shows “Service” or wrench icon and softener may continue to operate but indicates a fault condition.

Safety first: No immediate hazard, but avoid opening pressurized components without depressurizing.

Review controller status:

• Access the service menu on the controller to view any stored error codes or service reminders.
• Record any codes and address them individually (flow sensor, motor, brine, etc.).

Basic maintenance:

• Check salt level and condition of the brine tank.
• Inspect for leaks around the control valve and plumbing connections.
• Verify that the unit is regenerating on schedule and that water hardness after the softener is within expected range.

Reset indicator:

• If no active faults are present and the message is a time-based service reminder, follow the manual to reset the service interval.
• If the indicator returns quickly or is accompanied by other errors, schedule a professional Kinetico service visit.
