If the problem with your Maytag washer is that it shakes and it runs out of balance no matter how much clothes are in the spin drum during the spinning cycle, the problem could be bad damper pads.
The damper pads are used to help to keep the spinning drum in the middle of the washer when the washer is on the spin cycle.
