Will not Drain WCVH6260?

Hi, GE Washer, Model WCVH6260is not draining. Have removed the hose to the outside pipe, no overflow coming from that pipe. Removed the lint trap and cleaned out thoroughly. Have drained water via trap and also checked the inner tubes...no more obstructions. Washer is 4 years old. Starts, twists, washes but once gets to 18 minutes it does not DRAIN..it stops. I can hear a high pitched noise when I try to do a rinse/spin but does not spin?
