Info, impact, causes, and troubleshooting a "Device Valve Decoder Short Circuit" message.

Common causes

• Issue related to the solenoid or zone wire. 
• Solenoid may have failed due to a low continuity short. 
• Solenoid leads could be touching. 
• Zone wire may be shorted to the common wire.

What happens now? From the alert message:

• biCoder serial number: E188171.
• Zone 12 has a solenoid short preventing operation. 
• Irrigation for zone 12 will not run.
• Before troubleshooting:
  • This alert ONLY applies to solenoid side of the biCoder, not the two wire path. 

Troubleshooting

• Replace the solenoid or DBR/Y6 splices if needed.
• Cap off any unused biCoder outputs or extra wires going to a solenoid to prevent shorts.
• If the zone wire is shorted, use traditional wire repair tools to isolate the short.
