BB-8 not moving but motor whirring

Our BB-8 makes a whirring sound (seems motor is working) but it isn’t moving. It does move a very small amount of times but rarely. Can this be fixed? Has something disconnected inside?
It’s around 18 months old but has worked up to now. Anyone know why?


Hi (n_n) I just got one recently, and it doesn’t move, just turn on leds, I don’t know if the battery is low (maybe was a long time in stock) or if the gyroscope is damaged, some idea :'C
