Possible Causes
Failed real‑time clock circuit on PCB, Depleted backup battery or supercapacitor, Unstable mains supply, Corrupted control firmware
How to Fix / Troubleshooting
Safety first: Isolate power before opening the control head.
- Check supply stability: Ensure the softener is connected to a stable mains outlet or fused spur. Avoid extension leads or circuits with frequent interruptions.
- Reset time and settings: Follow the Kinetico programming instructions to reset the current time, hardness, and regeneration parameters. Observe whether the unit keeps time after a short power interruption.
- Inspect PCB backup component: Some models use a coin cell or supercapacitor for memory backup. If accessible and user‑replaceable, replace with the exact specified type.
- Firmware reset: Perform a factory reset if the manual provides a procedure. Re‑enter all settings.
- If E06 persists: The main control PCB likely requires replacement by an authorised technician.
Warning: Incorrect programming can lead to hard water or excessive salt use. Record existing settings before performing a factory reset.
