After an initial misdiagnosis on my part (thought it was from the pump seal), I took the time to watch the full cycle and determined the leak was from the diverter motor seal. As this seal is only available as part of the complete sump assembly, I watched the repair video, read other customers stories, and decided to order the sump and make the repair myself.
The part arrived quickly (as they always do) and I made the repair without any issues. Probably about an hour. And best of all, no more leak. If you have the factory installed clamps on the pump to sump, you'll need to buy a new clamp as the factory crimp type clamp isn't reusable.
