I'd check the ground wire at the valves and the controller. See if it came loose.
Possibly there's a shut off valve that shuts off those three zones only.
Turn on one of the valves manually at the valve to verify there's a water supply.
Maybe someone turned the flow controls off on those three valves.
I'm swapping out a controller in the morning, that toasted the controller connections to zones 8 & 9. Fortunately the valve that was on zone 9, was in the same valve box as zones 10, 11, & 12. First I swapped wire(s) at the clock. After that didn't work, I was able to swap wire(s) in the valve box, and the clock. That told me that the zone 8 valve was ok, as was the multi-wire strand.

3 Stations Not working
I have a Toro TMC-212 Control box with 8 stations. I have programed the watering schedule and all stations used to work. Lately station 6, 7, 8 quit working in both programed or manual operation. Anyone have an idea what might be the problem & where I might troubleshoot? There has been no digging in the yard so no cut wires. There must be some sort of commonality that causes 3 sequencial stations to quit at once.
