Works for MOVA LiDAX Ultra (800 to 2000), LiDAX Ultra AWD (1000 to 3000 AWD) and LiDAX Pro 800.

Short answer

What it means: The front bumper sensor is triggered all the time, so the mower thinks it is always hitting something.

Quick fix: Check whether the robot is trapped and free it.

Fix it in 3 steps
