I recently swapped from the R2 to R3. the R2 was working fine. I just rewired the R3 with 3 zones and a MV.
For some reason i can start zones, but they do not stop?? (this happens to all 3 zones).
The only way i can get them to stop is if i either unplug the rachio, or disconnect the common, or the specific zone wire. this is very strange? Does anyone know how to fix this?
ive just tried both again, and its happening with both controllers? I think it might be the valves themselves? Is that normal though, for them all to go bad?
It definitely could be the valves themselves! I would say the most common issues I see when zones won’t turn off is that the wiring is off or the valves are stuck open. Both fairly easy to troubleshoot and fix You can try and DIY fix stuck valves, but a lot of people prefer to contact a Pro.
Hmm… I’m not the best at irrigation system troubleshooting so I’m going to ping @DLane and @Gene in case they have any ideas. It’s worth it to double check that the wiring is solid as well - do you have photos of the setup that you’d be willing to share?
@sunnydays are you using the original power supply included with Rachio or have you had to buy a new one, perhaps because you needed 220V support?
What you are describing sounds very similar to a situation where a direct current (DC) supply is used, Rachio only supports alternating current (AC) supplies.
@sunnydays - Pictures help a ton! I’d ask for you to take a picture of a valve and it’s solenoid along with the Rachio like @laura.bauman asked. Any other information you can provide may give @Gene or me a hint/clue.
My initial thought was DC based solenoids, but I threw that out when it was mentioned that they were working on a Rachio Gen 2. By chance were the solenoids replaced?
Do you have access to a volt/ohm meter? If so, voltage reading coming out of the Rachio would be interesting along with resistivity down a zone line and back through the common wire.
