A B-hyve fault means the controller detected excessive current, usually from a shorted solenoid, crossed or damaged wire, wet splice, or too much load on one terminal. Record the station, disconnect power, then isolate the field wires from the timer before replacing parts.
Match the pattern before opening anything
| Possible cause | Best clue | First check |
|---|---|---|
| Bad solenoid | Fault follows one valve | Disconnect and test the coil |
| Shorted field wire | Fault remains with solenoid removed | Inspect cable and recent digging |
| Wet or crossed connection | Fault began after rain or service | Inspect terminal and valve-box splices |
| Overloaded terminal | Multiple valves share one station | Reduce load to rated output |
What this guide adds beyond the standard checklist
- First dividing test
- Capture the exact station fault: Photograph the app or timer message. A numbered station turns a broad controller problem into a specific circuit diagnosis.
- If the clue matches
- If you observe “Fault follows one valve,” move bad solenoid higher on the list and start with: Disconnect and test the coil.
- If it does not
- If that clue is absent, do not force the first diagnosis. Compare the system against “Fault remains with solenoid removed” and check: Inspect cable and recent digging.
Worked exampleYou cleared the B-hyve fault in the app, but it returned during the next run. The result changes the next move: Remove the field load from that terminal and see whether the timer faults with no station wiring attached.
Original conclusionThe controller reset its warning, then detected the same excessive-current condition again. Remove the field load from that terminal and see whether the timer faults with no station wiring attached.

Check these in order
- 01
Capture the exact station fault
Photograph the app or timer message. A numbered station turns a broad controller problem into a specific circuit diagnosis.
- 02
Disconnect power and label wires
Remove power before moving conductors. Label the station and its common path so you can restore the original configuration exactly.
- 03
Test the timer with the field load removed
Orbit recommends removing the identified station wire and associated common, then running a short test. A fault with wires removed points toward the timer; no fault shifts attention into field wiring or the solenoid.
- 04
Inspect waterproof splices and coil
Open the valve box and check for crossed copper, water-filled connectors, corrosion, or damaged insulation. Test the solenoid separately rather than replacing both valve and controller.
- 05
Restore one known-good circuit
After correcting the fault, reconnect one load, clear the message, and run a one- or two-minute test. Stop if the fault returns immediately.
- The short is underground.
- Several valves or a pump relay share the output.
- The timer faults even with the affected field conductors removed.
What homeowners ask about this symptom
Can a B-hyve fault be caused by the controller?
Yes, but isolate it. If the same terminal faults with its station and common field wires removed, the timer becomes the leading suspect.
Why should I disconnect the common too?
Removing both conductors isolates the external circuit more completely and prevents a shared field path from confusing the test.
