I have replaced the impeller, and all gaskets - including the pump tub gasket and my Kenmore dishwasher is still leaking around the black plastic piece that the check valve screws into. The check valve has a black flapper (preventing backflow), a small wing and an O ring that all look to be in good shape.
What else could be making it leak...?
ANSWER Kerry, The Check valve assembly 675238 is screwed into the pump base 675238, You'll need to check and make sure the pump base is not cracked or damaged, and that you have not overtightenned the check valve, when you installed it.
