Culligan Incorrect Metered Capacity or Reserve Setting

Softener appears to regenerate too early or too late based on water usage

Possible Causes

Capacity set too low or high, Reserve percentage mis-set, Flow meter miscalibrated, Hardness misprogrammed

Safety: Only programming changes are needed.

Review capacity: Confirm the programmed capacity matches the resin volume and salt dosage recommended by Culligan.
Adjust reserve: Modify the reserve setting (gallons or percentage) so that regeneration occurs before hardness breakthrough but not excessively early.
Verify hardness: Ensure the hardness value used for programming matches your actual water hardness.
