Diagnosing a 'Short' Error on a James Hardie Sprinkler System

James Hardie Controller Shows 'SHORT' and Stations Click

A "SHORT" message with clicking relays indicates a short circuit in the valve wiring or a solenoid drawing excessive current. The controller itself is rarely the cause.

Typical Fix

If the valves are 5+ years old, replace all solenoids—they often short internally with age.
Inspect field wiring for damaged insulation, especially at splice points.
Use waterproof wire nuts on all connections.

Solenoid replacement is a DIY‑friendly task; guides at irrigationtutorials.com.
