Autotrol Drive train or cam assembly noise.

Autotrol softener makes loud clicking or grinding noises during regeneration.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn or broken gears, misaligned camshaft, failing drive motor bearings, debris in gear train.

Safety: Disconnect power before removing the control cover.

Inspect gears: Remove the control cover and observe the cam and gear assembly during a manual regeneration. Look for wobbling, skipping, or missing gear teeth.
Clean debris: Remove any foreign objects or plastic shavings from the gear area.
Replace worn parts: If gears are worn or cracked, replace the Autotrol cam and gear kit. If the motor is noisy or has play in the shaft, replace the drive motor.
Lubrication: Use only manufacturer-approved lubricants if specified; many Autotrol gears are designed to run dry.
Test operation: Reassemble and run a full regeneration to confirm noise is resolved.
