The humming noise is the drain pump trying to spin. Bail as much water out of tub using a small jug as you can. Turn power off, tip machine back against wall as far as you can. Look under at front right corner of outer plastic bowl & locate drain pump. Try turning the plastic fan by hand back & forward a few times to see if it comes free. Stand machine up & advance to final spin. Press start & see if pump runs. If it won't come free & still hums then the pump will have to be taken out to clear the obstruction.
