When replacing the impeller does it matter which way it goes back in the housing? I made sure all the "arms" were going the same way but didnt know if they had to be turning a particular way.
The impeller has dots on one side and slash marks on the other, one is up and the other is down. The drive shaft turns clockwise, so the impeller blades need to be turned accordingly. Maybe pull it apart and be sure you've got everything right.
