Is only one zone out of several not working? You can check the output of the controller using a multimeter. If that checks good, then check the wires at your valve. Should be close to 24VAC.
Yes, don’t make sence. If the voltage was present on all of the terminals, it would be unlikely that only one zone would run (I’d expect that they all would). Can you see if you can remove the top housing and take a photo of the logic board itself?
One more thing, I would double check the valves within the valve box itself. One side of valves have to be tied together and the bundle tied to the C terminal, but if the valves are miswired, you may be getting a short which puts the voltages on all of the terminals.
Did you test the Rachio terminals with the wires still connected? Test it with the wires disconnected (or short pieces of wire inserted instead of your control wire). That way you know what the controller is outputting and eliminate any shorting further downstream.
Ho, how did you fix the issue. When i send the order to start watering, the pump/valves make a noise, i feel vibration while on, but no water. Thank you
