If the hose screws in, it might just be a loose fit, with wter leaking
out around the threads. You might try unscrewing the hose, and wrapping
the threads with thread tape. It's a white, soft, weird-textured tape
stuff...check in the plumbing section at Walmart or any hardware store.
Wrap a layer or two of this around the threads, press it against the threads
firmly, and screw the hose back in. The thread tape will smush in
around the threads and stop any leakage that might be occuring there.
