Charging station indicator lamp flashes blue — Break in boundary loop

What does Flashing blue LED mean?

The indicator lamp on the charging station flashes blue, signaling that there is a break or interruption somewhere along the boundary loop wire, preventing the robotic lawnmower from operating correctly.

• Physical damage to the wire (e.g., from gardening tools, ground frost, high tension during installation).
• Damaged wire insulation which may cause issues weeks or months later.
• A defective splice in the loop wire (e.g., coupler not pressed firmly enough, low-quality coupler).

Click steps to track your progress.

1. 1

   Visually inspect the entire length of the boundary wire for any visible cuts, nicks, or damage.

2. 2

   Verify that the boundary wire connections at the charging station are clean, secure, and undamaged.

3. 3

   Check all known wire splices to ensure couplers are properly crimped and are of the original or equivalent high quality.

4. 4

   To locate an invisible break, gradually halve the distance of the suspected wire section to pinpoint the faulty segment.

5. 5

   Ensure the cutting height was set to maximum for the first weeks after installation, then gradually lowered, as low cutting height can damage insulation over time.
