What to do if my BWS Control Unit shows a Regen Failure?

  Michael YoungAug 5, 2025
  To resolve a Regen Failure in your BWS Control Unit, start by performing a manual regeneration to clear the error. If your system is metered, ensure it's measuring flow by observing the flow indicator during water usage. If there's no flow measurement, check the meter cable connection and meter functionality. Access Master Programming Mode to confirm correct unit configuration, including system capacity, day override settings, and meter identification. For Day-of-Week systems, verify that at least one day is set to ON. Adjust any incorrect settings accordingly. This issue arises when the system hasn't regenerated for over 99 days, or 7 days if set to Day-of-Week mode.

  If your BWS Control Unit displays a Cam Sensor Error, the valve drive might have taken longer than 6 minutes to advance to the next regeneration position. Begin by unplugging the unit and inspecting the powerhead. Ensure all cam switches are properly connected to the circuit board and functioning. Verify the motor and drive train components are in good condition and correctly assembled. Check the valve to ensure the piston moves freely. Replace or reassemble components as needed. Plug the unit back in to observe its behavior; it should cycle to the next valve position and stop. If the error persists, unplug the unit and contact technical support.
