How to Fix / Troubleshooting

Safety first: Unplug the unit before opening the control head.

  • Observe during regen: Start a manual regeneration and listen closely to locate the noise source (motor, gears, valve body).
  • Inspect gears and cam: Remove the cover and check the Watersoft drive gears and cam for missing teeth, cracks, or misalignment. Replace damaged parts.
  • Check for debris: If grinding occurs at specific points, internal valve debris may be causing binding. A piston and seal kit plus thorough cleaning may be required.
