Kinetico electronic softener shows E09 and salt consumption is abnormally high.

Safety first: No internal electrical work is required for basic checks, but isolate power if removing covers.

• Verify hardness setting: Compare the programmed hardness with the actual mains hardness (from Kinetico test kit or water report). Adjust to the correct value following the user manual.
• Check for internal bypass leak: With no water being used, observe the meter reading or flow indication. Any movement suggests a leak or running appliance. Isolate appliances one by one to identify hidden usage.
• Inspect flow meter: If the meter shows flow when there is none, the turbine may be sticking or the sensor may be noisy. Clean or replace the turbine flow meter assembly.
• Recalculate capacity: Ensure the programmed capacity matches the resin volume of your specific Kinetico model. Incorrect capacity will cause too‑frequent regenerations.

Warning: Do not arbitrarily reduce regeneration frequency below recommended levels; this can lead to hard water and resin damage.
