The loader control valves usually have a detente mechanism in the valve it the bottom. There should be some detente balls that release the cylinder and allow for movement. If you remove the metal caps, that should expose the mechanism. Water could have gotten it the caps and seized up. If you take it apart, it should look fairly simple. It could be that cleaning and lubricating will free it up. It may require parts.

Just went through this with my LA481 loader. Though it wasn't the roll-back, it was the boom detent loosing float function. Pulled cap off and it was loaded with rust. Cleaned, lubed, reassembled, works smooth as butter now.

I'd suggest searching for a WSM or at the very least, a parts diagram so you know what to expect inside your valve when you disassemble. Some detent's under that cap (like mine) have ball bearings and a spring. Easy to loose those if your not careful.
