Blue flashing light

Blue flashing light — Boundary loop issue

husqvarna · Automower 115H

What does Blue flashing light mean?

The indicator lamp on the charging station flashes blue, indicating a problem with the boundary loop. This could mean the wire is disconnected or has a break.

Common Causes

  • Boundary wire not properly connected to the charging station
  • Break in the boundary loop wire

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Check that all boundary wire connectors (L and R) are securely and properly fitted to the charging station.

  2. 2

    Ensure ECO mode is turned off if you are using the wire break detection method (refer to page 25).

  3. 3

    To locate the break, switch the connections between the L boundary wire and the GUIDE wire at the charging station. If the indicator lamp turns solid green, the break is in the boundary wire segment between the original L terminal and where the guide wire connects to the boundary wire.

  4. 4

    If the lamp is still flashing blue, switch the connections between the R boundary wire and the GUIDE wire at the charging station. If it turns solid green, the break is in the boundary wire segment between the original R terminal and where the guide wire connects to the boundary wire.

  5. 5

    Follow the detailed method on page 43 to narrow down the exact location of the break.

  6. 6

    Once found, replace the damaged section of the loop with a new wire and splice using original couplers.
