This is an interesting problem where the pvc looks like it is not level and makes the hydrominder stick. I am not sure how this problem just started though. It was leaking into the presoak tank and on the floor. I also have an action packed video.

If you can’t solve the problem by straightening the PVC, you can solve it by bending the wire on both sides just below the metal plate. It will also be less likely to stick if you put the tips of the wire in the holes between the two magnets instead of hooking them on top.
I think the white float is sitting too low in the water. My guess is it has some water in it. Pull it ouit of the tank and look at it. You will be able to see if there is water in it. If there is you can unscrew the cap and empty the water, but if it has water in it it most likely has a leak and will happen again and needs to be replaced.
