Hotpoint WM19P motor wont do anything?

I have just brought this machine (second hand) and thought i check it over took the lid off and done a quick washer everything worked but there was a lot of arcing.

Changed the brushes for nice shiny new ones again done a wash the arcing had gone then when it went into spin the arcing reappeared with a vengence a loud pop and whole house tripped out.

Took to bits again and gave the armature a lite clean put back together, she fills and empties but nothing from the motor.
Does it need new motor or is the control board fried????

Also looking for a manual??
