When full with water the inner bowl floats up & this disengages the drive cog for the inner bowl. After the water drains out the control module makes the bowl jerk to make sure the bowl drive cog has re-engaged before spinning. With the bowl empty, grip the inner bowl on either side & pull up. Bowl should slide upwards easily & by turning you will feel it is free. Let it go & check that it slides right back down & you should feel it engage. E-mail me if you still have a problem.
