Grains of hardness in your water supply have increased

Water hardness can change over time, especially in well water. To check, have the water tested by a water analysis laboratory or call your local water department. Adjust the hardness number setting as needed.

System capacity inputs, Salt per Regeneration and Capacity set too low

See Salt per Regen and Capacity section so system will regenerate about every 5 days. See instructions on pages 12 and 13.

If resin bed is fully exhausted, for example, after a malfunction, one regeneration cycle may not fully restore capacity

Complete “back to back” regenerations. Initiate Regeneration cycle, wait 1 minute, then press REGEN again.
