There is either a balance issue or a damaged spring. Usually all you need to do is open the washer (make sure it is OFF) wait for it to stop spinning... then look for clothes bunching up on one side. Take some out ad move them around. Sometimes putting in to many or too few items will make it harder to resolve. Items like large towels or several towels, sheets and such will hold more water and be heavy until the water starts to pull out.
