troubleshoot: sprinkler system stopped working

We noticed that our sprinkler system stopped working.
I tested using Manual Mode (Single Station).
The controller (Hunter Pro-C) shows that it is running (with the
sprinkler icon and time count-down), but no water comes out in the field.
The last time I saw the sprinkler system working fine was in April.

(I located the "irrigation control valve" (it says so on a green cover) and tried to turn the black cylinder with 2 wires (?solenoid), and nothing happened. So it means that it cannot be manually opened?)

Your system may have a master valve, which will prevent a manually-opened zone valve from producing any flow of water.

The system may also have a rain detector which is not allowing watering.

Time to do some resistance testing of the wiring, to see if you have continuity.
