Autotrol softener stuck in regeneration and will not return to service position

Safety: Immediately place the valve in bypass to restore water to the home, then disconnect power and relieve pressure.

• Inspect drive assembly: Remove the control cover and check the camshaft, gears, and motor. Look for broken gears or a seized cam.
• Check piston/rotor-disc: Remove the Autotrol valve module and inspect the piston or rotor-disc and seal pack for swelling, scoring, or debris. Replace if damaged.
• Test motor: With the cam disconnected, power the motor during a manual regeneration command. Replace the drive motor if it does not turn.
• Control board: If the motor and mechanics are good but the valve does not advance, replace the electronic control board.
• Reassemble and test: After repair, run a full regeneration and confirm the valve returns to service.
