Hi. I moved into a home last summer that has a Rain Bird ESP-6Si system. 6 stations. Worked great last summer and fall. It was set to an auto program that ran every 3 days. We switched the auto-function off during the winter. But this spring when we turned the auto function back on, the system hasn't worked. it won't even run via manual start (for each station). No error messages showing on the controller display. The controller has power. Any ideas? I'm not the handiest guy in the world, but I can adjust something (if possible) if you think it needs to be adjusted. Before I call an irrigation contractor ($$$), does anyone have a suggestion re: what I should check/adjust/look_at? Thanks.
