No water
Here's a couple of ideas. Possibly the fuse is blown and the controller appears to be running but is just working off the back up battery. Possibly the ground wire is disconnected somewhere. Possibly all the wires are cut in half. Did you do any digging recently? Possibly the water supply is turned off to the valves. Possibly the rain sensor is causing the problem. You could disconnect it to see. Maybe there isn't any electricity coming out of the outlet and again the controller is running off the back up battery. Maybe the controller itself isn't putting out the right amount of power to activate the solenoids. I'm thinking the answer is in there somewhere.
Good luck!
If I can't fix it, it's broken!
