- Solar Panel Cleaning: Keep the solar panel clean and free of dirt or debris to ensure optimal charging efficiency.
8. Troubleshooting
- Timer Not Turning On / Display Blank:
Possible Cause: Dead or incorrectly installed batteries. Insufficient solar charging.
Solution: Check battery polarity and replace with fresh AAA batteries. Ensure the solar panel is exposed to direct sunlight. - Water Not Flowing / Valve Not Opening:
Possible Cause: Low battery, blocked filter, incorrect programming, or tap is off.
Solution: Replace batteries. Clean the stainless steel filter screen. Verify your watering program settings. Ensure the main water tap is fully open. If the display shows a low battery indicator, turn off the tap, replace batteries, and reset the watering procedure. If batteries are not replaced, keep the valve permanently off. - Water Leaks from Connections:
Possible Cause: Loose connections, worn washers, or damaged threads.
Solution: Tighten all connections. Check and replace rubber washers if they are worn or damaged. Apply plumbing tape if necessary. - Programs Not Running as Expected:
