Charger fault
The system has detected a fault in the charger. Bosch's official instruction is unusually clear here: replace the charger and contact the dealer. Riding is not affected — the bike simply cannot be charged with the defective unit. Before buying a replacement it is worth trying a different mains socket and checking all plug connections.
