Why does my Husqvarna GARDENA SILENO MINIMO Lawn Mower say no loop signal?

C

If your Husqvarna Lawn Mower displays 'No loop signal', several factors could be at play. First, ensure the boundary wire isn't broken. Next, verify that the boundary wire is correctly connected to the charging station. Check the power supply connection to the wall socket and examine the low voltage cable for damage and proper connection to the charging station. If ECO mode is active, place the mower in the charging station and start it from there. If the pairing is broken, place the product in the charging station and generate a new loop signal. Also, confirm that the boundary wire isn't laid incorrectly around an island. Finally, disturbances from metal objects or buried cables can cause this issue, so try moving the boundary wire or creating additional islands.
