Hi. I bought a replacement impeller assembly for my Bosch DW. I looked at these two videos
Impeller Kit Replacement (part #167085) - Bosch Dishwasher Repair - YouTube
How to repair a Bosch dishwasher that squeaks and doesn’t clean - YouTube
To see how it’s done. I got all the way to rotating the motor assembly the expected 45 degrees, but the motor will not pull away from the circulation pump housing as shown in either video. It feels like there’s something holding the motor in place from the inside. I felt around the flange as best as I could and it does feel like it has loosened from the outside. It just won’t pull away. Need help.
