Every washing machine will vibrate at some point. So it is just normal for the washing machine. But if your washer is constantly vibrating, there might be a problem. First, check to see if the load is balanced or not. Second, take a look at the legs of the washing machine. If they're not level, the machine will shake. Finally, check the hoses to see if they're kinked or frayed. But don't worry—a slight shaking is perfectly normal.
