There are various reasons why a Toro Sprinkler won't turn on.

Sprinkler Valve

The valves are responsible for switching sprinklers off and on. If the valves are faulty, there will be instances when your sprinkler won't work.

Electrical Issues

Locate the drier part of your lawn and check the valve in that area. Open the valve to see if the water sprays out.

If this happens, check the sprinkler's electrical connections using a multimeter to measure the voltage. If it is dead, you may need a technician's help to fix the electrical wiring.

Here are some of troubleshooting procedures that you can do to figure out why your Toro sprinkler timer is not working:

Timer Has No Power

  • Check the circuit breaker to see if it is off or if the fuse has blown. Replace the fuse if needed.
  • Unplug the end of the power cord's transformer. Use an electrical circuit tester to test the outlet to check if there is power. If you are not confident enough to do this, find someone to work it out or get an electrician to assist you.
  • Plug in the transformer. If there is power in the outlet, but the timer display is still off, then replace the transformer.

Watering Issues

This is the same issue with why the sprinkler won't turn on. If the timer does not turn on, there is a possibility that the valve is faulty or it is dirty. Try to clean the valves first if it will work. If the timer still doesn't work, reset the Season Adjust.

Program Won't Activate

Check to see if the dial is "Off" if the timer doesn't turn the sprinklers on or if the start time has not been programmed yet to ESP.

Change the switch to the program desired and ensure the dial is to "Set Watering Start Times" to confirm the start time. If you can't see the start time, push the button up and down to set it.

ESP Problems

ESP activates the sprinkling system to water the lawn and garden at your desired time. The valves are wired to the controller and connected to the sprinklers.

  • Turn the dial to "Off" to turn off the water. If turning the dial off won't work, check your sprinkle valves to find other causes. Seek help from a professional if you are not confident enough to troubleshoot. If the water shuts down, you can continue manually programming the timer.
  • Ensure the dial is on the "Set Watering Start Times" setting.
  • Toggle between start times by pressing the left and right arrows. Turn off the other start times.
  • To change the time settings, press the - or + buttons. You will see the "OFF" function of start time between 11:45 PM and 12:00 AM.
  • Keep the time on OFF.
  • Return the dial to the "Auto Run" setting.
