The pump does not start on schedule; the timer or programmed speeds are not being followed.

Safety first: Ensure the pump area is dry and safe while programming; no need to power off for keypad-only changes.

• Verify current time: Use the Harris keypad to check and correct the current time and date.
• Review schedules: Confirm that start/stop times and speeds are correctly programmed and are not overlapping or disabled.
• Check for power loss: If the pump frequently loses power, consider installing an uninterruptible power supply for the control circuit or correcting the electrical issue.

If schedules still fail to run correctly, the internal clock or memory on the control PCB may be failing, and the module should be replaced.
