I went out tonight to help a neighbor start-up his irrigation system for the spring. The irrigation controller that was installed is a Rainbird ESP 4 zone controller with a 3 zone expansion module in use (7 total zones). I went to the controller, turned the dial to Auto and pressed the manual start button. Zone 1 popped-up and sputtered for about a second or two and went down. I turned the dial to the off position for a moment and back to Auto and pressed the manual start button again. Same thing, zone 1 popped-up and sputtered for a second or two and went down. I then pressed the test button and all of the zones came on and operated appropriately at this point. But, this is actually the second or third time I have seen this happen with manual start feature over the last few years. Has anyone run into a problem like this with the Rainbird ESP? If so, what did you do about it?
