Removed the back panel, noticed the bolt that holds the rotor assembly was loose. Inspected the rotor assemble and determined the plastic center sprocket was completely stripped out. Reviewed the video on Appliance Parts Pros and ordered the part. Installed the new rotor assembly, the washer has returned to normal operation. In the second review of the video, I discovered I forgot the Loctite on the retaining bolt. Opened it back up and got some Loctite on the bolt. Done.
