The tub did not rotate.

I'm a retired industrial machine mechanic of 40+ years. I found you instructions very good. I can not kneel. So I tilted the unit Back to rest on the deep sink. This was a good position to clean and replace the parts I ordered from your company. Witch were a perfict fit. My unit has a bottom hinged door. That's what I used the 2" C clamp for. To keep the door from slamming shut. Thank you for all your support. It was outstanding.
