The valve leaks at the spot where the hose connects to the faucet. It has leaked with two different hoses. I'm trying to replace the valve, but it is not easy to get off. Is it designed to come off? Or do I need to hire a plumber to come in and cut the wall open and cut the pipe?
Appliance parts like are generally specific to the manufacturer and possibly model. My usual approach, which has served me well, is:
You might also try a local appliance repair parts store -- they may be able to guide you to find the right part if they are familiar with your brand of appliance.
When you go to product site check out the "for owners" tab and open the second installation and care guide. On page 2, it shows the handle itself unscrewing so you can replace the red or blue color rings. Start opening it up there and see if you can work your way down to screw 55431 which is holding down the rest of the faucet to the valve.

The threaded part on the valve where the hose connects seems, from the picture, to be rather short. It is possible that the part on the end of the hose is interfering with the valve body (represented by the green arrows in the diagram below) before the rubber hose washer gets a decent amount of compression on it.
If this is the case you may be able to purchase a thicker hose washer that is more supple than what is currently in the hose end to allow for the proper compression to seal the joint.
Also, as stated previously in the comments, it is often necessary to use a tool to turn the hose coupling tight to get a good seal.
