Hardie Controller Runs Continuously: Valve or Controller Fault?

A Hardie irrigation controller runs non-stop in Manual, Auto, or Off modes. The user seeks a way to shut it down and identify the root cause.

Isolating the Problem

Disconnect power completely from the controller. If the system continues running, the issue lies with stuck-open valves, not the controller. If it stops, the controller is defective and likely needs replacement.

Follow-Up: Manual Works, Auto Doesn't

After testing, the system runs in Manual but not Auto. This suggests a programming issue rather than valve failure. Obtain the manual for model HR-6100 (60Hz, no pump start) from Coast Water Works (search "irrigation controller manuals"). Ensure the first switch is set to Auto, the second to Run, and the main dial to Current Time. If automatic operation still fails, replace the controller—the HR-6100 hasn't been manufactured in over a decade. The current equivalent is the Irritrol Rain Dial.
