Pump is unusually quiet and appears to be running, but there is minimal water movement.

Safety first: No internal work required; adjustments can be made via the controller.

• Check current RPM: View the current speed on the Hayward pump display. If very low, increase RPM temporarily to see if flow improves.
• Review programs: Ensure that the active schedule is set to an appropriate speed for filtration or cleaning.
• Automation settings: If controlled by automation, adjust the speed settings in the automation interface.
• Balance efficiency and flow: Set a minimum speed that maintains adequate skimmer action and circulation while still saving energy.
