We did a little googling, and discovered that a small part inside the knob had worn away or disintegrated, so the integrity of the knob just wasn’t good anymore. A few bucks on this replacement part, and we quickly fixed our problem! The waterfall turns off no problem, and actually switching out this part was a cinch. Definitely a great value! Review: Perfect fit for my Catalina hot tub - I found this doing a search for a replacement fountain control valve. It was easy to use and it even came with a small tube of silicon grease to lubricate the cartridge.
