I am having trouble with my zones shutting off before the cycle ends. When I turn on a zone it will work then stop before the cycles is done, and then if I go to any others zones they won’t respond either. When I go back later it suddenly starts working again when I turn it on, then stops working again. When I went to one the valve box in front of the back flow preventer, and turn it on manually then all the zones work fine (I assume this is a master valve for all the zones), but if I turn it back off manually then problem comes back. I replacEd the solenoid thinking that was the problem, but I’m still having the same issue. FYI, I just replaced the control panel today, and I’m still having the problem. So it’s not the solenoid in the valve that I replaced, and it’s not the timer, so what could it be? Confused and frustrated, please help!!!!!!!!!!
