if the washer goes through a wash cycle normaly but wont spin the fault will be with the door safety interlock. Try opening the door during the very start of a cycle whilst it starts to take on water. only open it a fraction as not to get water all over the floor, If the door opens then this will confirm the interlock fault. A new interlock is straight forward to fit. Give it a try. Good luck.
