Old pump was draining, but still had consistent drain failure codes.
Replaced drain pump and other pump in same assembly as well as both inlet screen filters and the drain hose (to ensure it was not compromised by debris).
Replacement video did not exactly match my unit, but was sufficiently informative to cover the difficult parts of disassembly.
Needed a 10mm nutdriver to remove the pump assembly platform.
Note there are TWO screws associated with the drain cover and front panel attachment as well as another screw at the top of the instrument console that are not discussed in the video.
