MY washer keeps tripping electric?

My washing macine keeps tripping electric?
My washer tripped the electric half way through a wash, so i took the brushes out and one had no carbon on at all and a spring just popped out but the other brush was fine. So i bought some new one fitted them in but still tripped the electric?

So then i took them out while the brushes were still connected and the washer started filling up with water not tripping. So put it off again then put them in and tried it and still tripped. so i tested each side by taking one out and leaving one in. And fount if the left side is put in it trips, but if the right on is in its still starting up?
