Yes that is normal. You shoud also be able to move impeller blade
backand forth on the armature about 270 deg as well. If its rattling
the usual cause is air impinging onthe blades.........watch inside the
inlet U tube for any signs of even small air bubbles. How high is the
water in the tank? Fill it to at least the botom of the top trim if
its not. Its not allthat common but they have had a few U tubes that
had a crack in them from what I heard. ALso make sure the U tube is
seated firmly down in its seat and not onthe little edge around the
seat it goes into.
