Not sure what is going on. Suddenly, all 15 zones stopped working.

Metered the in-coming voltage - 28.9
Metered the voltage on each zone - each zone ranged from 25.6 - 25.8
Metered the ohms on each valve- all good.
Tried re-setting the controller. No luck.

Checked to make sure the water was turned on at the DC. It is..

What am I missing? ?(

TIA..

Is there a rain sensor or something installed?
Go out to the valves and see if there's water and power there. One of the two isn't working.
DC? What's a DC?
Is there a master valve? See if there's water n power there if so.

Thanks for the reply.



Yes, there is a rain sensor. I did check the sensor and made sure the
controller was in by-pass so it would not interfere with the controller's
normal operation. That did not help.



DC...sorry I meant DCA..double check assembly.



Yes, there is a master valve. After I wrote this post yesterday, I started
wondering if it was possible the "SET PUMP/MASTER VALVE OPERATION"
settings for each valve may have somehow been compromised. I will check that
later today.

Yesterday, I finally had a chance to spend some time on this. Once I determined everything seemed ok on the controller side, I went and located the master valve. I manually ran several of the zones with the master valve open and everything worked fine. I metered the solenoid on the master valve and got the same reading I was getting at the controller.
Based on all of this, my gut was telling me it was something in the valve itself not working properly. I took the valve apart, cleaned it thoroughly and replaced the diaphragm, spring and solenoid. Put it back together and system works perfectly. Thank you for your help!
