Sprinkler valve not turning on by automatic timer

sprinkler-systemtimer

I just programmed my sprinkler settings for Spring. I have back and front zones. 1-5 in the back, 6-8 in the front.

I noticed that station 6 is not turning on by the timer. It reads Err.

Here's what I've tried:

  • Station 6 turns on manually at the valve without the timer
  • At the timer, I took the 6 wire and doubled up on the 1 station. Timer read Err.
  • At the valves, I connected the 6 wire to the 7 wire/valve. I ran 7, and timer read Err.

Seems like any time station 6 is involved, the timer will read Err.

What kind of problem does this point to?

You have done good testing. Almost certainly the electric solenoid at the valve is defective, with a small chance the wire has a short.

Many designs of them can be replaced (leaving the rest of the valve in place).
