Pump will not start on schedule but runs when started manually.

Safety first: No internal high-voltage work is needed for this procedure, but do not open the control housing with power on.

• Check current time: Verify that the AquaFlo controller clock is set correctly, including AM/PM or 24-hour format.
• Review schedules: Enter the scheduling menu and confirm that start and stop times are enabled and not set to past dates or disabled days.
• Clear conflicts: Delete overlapping programs and re-enter a simple schedule to test.
• Confirm mode: Ensure the pump is set to AUTO or TIMER mode, not MANUAL ONLY.
