Get a small mirror and a flashlight and locate the leak.
Dry everything off and through sight/feel determine where the actual leak is, sometimes a leak can be higher up and it is just dripping from a certain part.

Could be the valve itself (replace it) OR the input line (may just need tightening) OR the output (may need a new clamp).

Also could be coming from the overfill float assembly.
Check the fill level usually machines fill to just below the heating element.
Remove the float cover and clean/check it.
Sometimes crud will build up in this area and siphon out some water.
Leak will be a few drops and only when there is water in the tub.
