Replaced the complete Drain Pump Assembly. The instructional video on Appliance Parts Pros provided excellent insight into what to expect during the swap-out process. The only thing I encountered that was not pointed out in the instructional video was the strong sewer odor that came out when the drain hoses were disconnected. It's only natural that nearly 20 plus years of use would cause sludge buildup in the drain hoses and I was able to clean it up but be prepared for the stink! Beyond that, I feel successful with the whole experience from finding to replacing the pump and repairing an otherwise great appliance.
