Couldn’t tell for sure where the water was coming from (looked to be leaking around the diverter motor but could not see well enough to confirm until disassembly) so I elected to replace the sump assembly “pump and motor assembly”. Took several pics of wiring before disassembly for reference. Also, watched Appliance Parts Pros’ demo video on YouTube. Repair went just as shown in the demo, with the exception that I did not remove the main pump motor from the sump. It will wiggle out and the new one back in by removing only the drain pump motor.
