Just one note on the Performa (Atlantis too), if a load gets off balance, the tub will not spin but a couple of turns a second. There's an automatic braking response if the tub travels too far near the cabinet. Be sure you always use the HIgh water levels, even with smaller loads to avoid having the load bunch up on one side of the spin basket.
Also, check to see that your pump is discharging a full tub of water in under 70 seconds. If not, you have pump issues. To find out, fill the machine to a high water level, then switch the timer over to a spin cycle and time the discharge until the tub is empty.
