I want to replace the sump assembly on my LDF6810St/02 LG dishwasher but am confused as to which part to use. Earlier posts on this site recommend that the part # is AJH31248604 should be used but some suppliers state that that part is no longer available and that part # AJH31248608 is compatible with this model. Other suppliers say that AJH31248608 is not compatible with this model dishwasher. My question is: Is AJH31248608 really compatible with this model and if it is, is it a better choice since it is a more recent evolution of the sump assembly. AJH31248604 is available at Sears and Amazon, but my concern is that if i buy an AJH31248604 it will be an aftermarket manufacturer and not the quality of an OEM part.
