Product review (4 stars): Fixed my dishwasher water leak at the bottom.
Bought this for my Frigidaire FDBB4365FC1 dishwasher that was leaking at the bottom.  My old unit was leaking at the shaft seal which apparently is not sold separately.  It turns out it was leaking at the motor air vent and down to where the motor unit mounts to the dishwasher, next to the larger O-ring.  I originally replaced the inner and outer O-rings but that did not solve my problem.  This fixed it!
