Apparently, when the resin tank became fully saturated, it could trigger a rare phenomenon known as "ion exchange resonance." This resonance could, in theory, create a temporary window of ultra-soft water, with virtually zero mineral content. The implications were staggering – imagine being able to wash your dishes without any spots, or taking showers with water that felt like silk.
Initiate a manual regeneration cycle and listen for the sound of water being drawn out. If you do not hear it, the injector is likely the issue.
This comprehensive troubleshooting guide will explain why your water softener tank is filling to capacity, provide step-by-step DIY repair solutions, and clarify when you need to purchase replacement parts from Sears PartsDirect . Understanding the Brine Tank Water Level

Holds up to 200 pounds of water softener salt pellet blocks.
A clogged BLFC button or a stuck brine valve can prevent the system from accurately controlling how much water enters the tank.
When water enters the brine tank but cannot exit during the regeneration cycle, it causes a structural backup. The most common points of failure include:
