Question
Sprinkler system has been working fine.  All lights are on, timer's set, etc.  They have not gone off at the designated times today and in checking the box a code comes up...3 05.  I've checked everything and this is the only thing I see that's different.

Answer
Hey Maggie, could you let me know what the brand and model of the controller is? Without this information I would not know what this code means. It is probably one of the solenoids on the valves that is shorting out. Let me know what you have and we can figure it out. Thanks and have a great day.
