How to Fix / Troubleshooting
Safety first: Unplug the softener before removing the control cover. Place the unit in bypass if you need to open the valve head.
Steps to check:
- 1. Listen and locate: Start a manual regeneration and listen to identify whether the noise comes from the motor/gear area or the valve body.
- 2. Inspect gears: Remove the motor and gear cover. Check for missing teeth, cracks, or foreign objects in the gears. Replace damaged gears.
- 3. Check rotor alignment: Ensure the rotor and disc are seated properly and not rubbing excessively on the valve body.
- 4. Replace noisy motor: If the motor itself is loud or rough when running free, replace the rotor/valve motor.
When to call a technician: If you are not comfortable disassembling the valve head, seek professional assistance.
