Solid blue

Solid blue light — Weak signal from long boundary wire

husqvarna · Automower 105

What does Solid blue mean?

A solid blue light on the charging station suggests that the boundary wire is too long, resulting in a weak signal. While the mower may still operate, its performance, especially in finding the charging station, might be affected. This is not necessarily a fault but a condition.

Common Causes

  • The total length of the boundary wire exceeds recommended limits for a strong signal.
  • The working area is very large, requiring a long boundary wire.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    If the mower is operating without issues, no immediate action is required.

  2. 2

    Consider shortening the boundary wire by reducing the working area.

  3. 3

    Replace any island sections with physical barriers the mower can collide with, if practical, to shorten the wire.
