Possible Causes

Stalled rotor/valve motor, Jammed rotor and disc, Stripped cam gear, Control board not advancing cycle

How to Fix / Troubleshooting

Safety first: Immediately place the unit in bypass to restore household water. Unplug the softener before servicing.

Steps to check:

  • 1. Attempt to advance cycle: Use the control panel to manually advance through regeneration steps. If it will not move, the motor or valve is likely jammed.
  • 2. Inspect motor and cam: Remove the control cover and motor. Check the cam and gears for damage. Replace any stripped or broken parts.
  • 3. Check rotor and disc: Remove the valve cover and rotor/disc. Clean debris and inspect for scoring or warping. Replace if damaged.
  • 4. Reassemble and test: Reinstall components, restore power and water, and run a manual regeneration to confirm proper indexing.

When to call a technician: If the valve body is cracked or the rotor cannot be removed, professional replacement of the valve assembly is recommended.
