Hunter SRC Plus 900i
System is 7 yrs old never had a problem. The panel lights up has electricity show to be working and counting down but no water is coming out. Individually tried all 9 stations in which they work. Does not have a master valve and never has had a 9 volt battery in it. I have reset the system and also tried to bypass the sensor Nothing. Out of ideas on troubleshooting. Anyone have any ideas on what else I can try before replacing the controller?
