Possible Causes

Drive motor failure on Crystal Quest valve, Position sensor not detecting cam movement, Obstructed piston preventing full travel, Control board logic fault

How to Fix / Troubleshooting

Safety first: Bypass the softener to restore water service, then unplug the unit before opening the control head.

  • Manually advance: Use the REGEN or ADVANCE button to step through cycles back to SERVICE. If the valve does not move, suspect motor or mechanical binding.
  • Inspect motor and gears: Remove the cover and observe the motor during a manual regen. Replace the Crystal Quest drive motor and gear kit if it does not run or is noisy.
  • Check piston: If the motor runs but the piston does not move, rebuild the valve with a Crystal Quest piston and seal kit.
  • Sensor check: Verify the position sensor/encoder is aligned and connected. Replace if the board cannot detect valve position.
