Reassembling A Vari-Flex KM Agitator
It will not work well with the fins not in place, with the fins out even on hi-speed agitation you are getting very little action.
Some one will have to remove the agitator bolt to fix this, you may be better off just putting in a regular agitator in if it can not be fixed easily, but in any event the washer is not going to be very useful without the three fins.
