Possible Causes

Worn or stripped gears, Failing drive motor, Misaligned cam, Debris in valve causing binding

How to Fix / Troubleshooting

Safety first: Unplug the unit before removing the cover. Avoid placing fingers near moving gears when powered.

Steps to address:

  • 1. Identify noise source: During a regeneration (with cover removed and extreme caution), listen closely to locate whether the noise comes from the motor, gears, or valve body.
  • 2. Inspect gears and cam: With power off, examine the EcoWater drive motor and gear train. Look for cracked, missing, or worn gear teeth and a loose or wobbling cam.
  • 3. Check for binding: Manually advance the valve (per service manual) to feel for tight spots. Binding may indicate internal valve debris or worn seals.
  • 4. Replace noisy components: Replace the EcoWater drive motor and/or gear kit if they are the source of the noise. If binding persists, rebuild the valve with a new seal pack and piston.
