Possible Causes

Control not initiating regeneration, Brine refill stage not functioning, Clogged brine refill port, Stuck brine float preventing refill

How to Fix / Troubleshooting

Safety first: Put the unit in BYPASS and unplug power before opening the brine tank.

Steps to restore salt usage:

  • 1. Confirm regeneration: Mark the salt level and monitor over several cycles. If the level never drops, the system is not using brine.
  • 2. Check brine refill: During the brine refill stage, observe whether water enters the brine tank. If not, inspect the brine refill port and valve in the Aquasana control head for blockage.
  • 3. Inspect float: Ensure the brine float moves freely and is not stuck in the up position.
  • 4. Verify programming: Confirm that regeneration is scheduled and that the unit is not in a bypass or service lockout mode.
  • 5. Service valve: If refill still does not occur, the internal brine valve assembly may need replacement.
