How to Fix / Troubleshooting

Safety: Unplug the unit and avoid electrical contact with standing water.

  • Stop overflow: Place the Autotrol valve in bypass and manually bail out excess water from the brine tank.
  • Inspect float assembly: Remove and inspect the brine float assembly for cracks or misadjustment. Replace if it does not shut off flow.
  • Clean refill flow control: Remove and clean the brine refill flow control orifice to ensure proper restriction.
  • Check refill time: Verify that the brine refill time is set correctly in the control programming. Reduce if excessively long.
  • Test refill: Run a manual regeneration and observe the refill step to confirm the float shuts off water at the correct level.
