Pump does not respond to schedule or timer settings on the built-in controller.

Safety first: No internal electrical work is required for basic programming; power can remain on.

• Verify time and date: Set the correct time and date on the Hayward pump controller.
• Review schedules: Ensure start/stop times and days are correctly programmed and not overlapping or disabled.
• Backup power: Some models rely on internal batteries or capacitors for clock backup. If time resets after power loss, the clock circuit may be failing.
• Factory reset: Perform a factory reset and reprogram schedules. If the issue persists, the control PCB may need replacement.
