Husqvarna Automower 450X NERA: Charging system problem

What this fault means

Charging electronics detect an abnormal supply, cable, contact or charging condition.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Confirm the correct Husqvarna power supply is fitted.
2. Keep the low-voltage cable within the manufacturer limit and inspect cable/connectors for damage.
3. Clean visible mower and station contact plates.
4. Restart once after power and contacts are verified.
5. If the same message returns with known-good external power components, stop parts-swapping and arrange mower/station electronics diagnosis.
