GD has power, hums. Used hex and reset button. all moves freely but the flange? moves side to side and doesn't stay flush. Impellers, not sure of their name but the little grinders move freely. Is the flange supposed to stay securely flush in the GD? It almost seems as if it isnt tight to the main shaft? Problem was originally GD would hum but wouldnt grind food. I have check all clogs, used wrench, reset button but noticed flange moves side to side at an awkward position. Do not know if that is normal. Any help or is it doomed to GD heaven? Thanks, Sally
