🔍 Why This Happens
Root cause analysis for your water softener's not softening water
The water softener resin in your water softener has failed due to a combination of age, normal wear, and operating conditions. Most appliance components have a predictable service life — when they exceed it, failure rates climb sharply. This is a more involved failure that may have developed over an extended period. With a 70% diagnostic match, replacing this part is the recommended first step.

🛡️ Prevention Tips
How to prevent your water softener's not softening water from happening again after this repair.
Keep the salt tank at least half full. Running out of salt exhausts the resin bed and allows hard water through.
Use clean pellet salt, not rock salt. Impurities in rock salt create sediment that clogs the valves and brine system.
Check for salt bridges every few months — a hard crust that forms above the water level prevents salt from dissolving. Break it up with a broom handle.
Set the regeneration frequency based on your actual water hardness and household usage, not the default setting.
After completing this repair, make a note of the date and the part replaced. Tracking repairs helps you spot recurring issues before they become major failures.
