The channels on the filter housing that the teeth of the wheel rest in often get clogged up with debris and/or calcium deposits. That eliminates the ability for the wheel to spin. You can try chipping out anything large or using vinegar to dissolve it. That may be overkill depending upon your situation though. Next up would likely be the wheel itself. Pull it out and make sure it is not bent or coming apart. If it is bent you can reconfigure it rather easily. If coming apart just reassemble it.
I tried pushing it down all the way for both & it doesn't work still. Plus tried changing the wheels & it's still not turning
This is a brand new filter out of the box so I don't think there's any build up. I can try taking the wheel apart to see if there's anything wrong with it. Thanks
It started spinning after I did a water change and messed with the flow a little bit!! Yay!! Weird though, I got 2 of them, the second one that I set up started spinning right away. I'm not sure why. But atleast it works!
This with as much emphasis as humanly possible.
