Softener not using salt; salt level in brine tank never goes down

Safety: Unplug the unit and place it in bypass before opening the brine system. Wear gloves when handling salt and brine.

Steps:

• 1. Check for salt bridge: Push a broom handle straight down into the salt. If you hit a hard crust with empty space underneath, break the bridge so salt falls into the water.
• 2. Verify water in brine tank: There should be several inches of water at the bottom. If completely dry, see refill issues (injector or refill valve).
• 3. Clean injector/venturi: Remove and clean the injector assembly on the Sterling valve to restore suction.
• 4. Inspect brine line and float: Ensure the brine line is not kinked and the float moves freely. Clean or replace the brine float assembly if it is stuck.
• 5. Test brine draw: Start a manual regeneration and observe whether the brine level drops during the brine draw step. If not, further valve diagnostics or professional service may be required.
