@kar465 that flashing is usually caused by the carbon brushes on the motor. WE would have to see what that looks like. you can wither post a short video or even a couple of pictures of where you see those sparks. If it is the brushes, replacing those will most likely fix this. KitchenAid KSM150PSER Carbon Brushes Replacement Adding images to an existing question
