First I googled and searched the problem. Brought me to a youtube instruction video. Popped off the agitator, unscrewed the coupler; yup there's the problem. Ordered new one, got new one in the mail (very fast delivery!), screwed the new one on, placed agitator back over it, and it works again :) Yeah! Thank goodness for the internet and super fast delivery, saved me at least a $170 on a service call.
