How to Fix / Troubleshooting

Safety first: Unplug the unit before removing the control cover. Do not place fingers near moving gears when powered.

Step-by-step:

  • Observe operation: During regeneration, listen to locate the noise source (motor, gears, or valve body).
  • Inspect gears: With power off, remove the AquaUnique control cover and examine gears for missing teeth or excessive wear.
  • Clean debris: Remove any plastic shavings or foreign objects from the gear area.
  • Lubrication: Only use lubricants specified by AquaUnique, if any. Many gears are self-lubricating and should not be greased.

When to call a technician: If gears or motor are damaged, replacement of the drive assembly or motor is required.
