Well, I figured it out...wasn't hard at all. In case anyone cares to know what I had to do I'm posting a reply to my own question.
It turns out that there's a safety mechanism (for children so they don't burn themselves) built inside the knob that doesn't allow people to turn the knob all the way to hot. It's a smart idea, but unfortunately I didn't want to have it...but to remedy the situation, I simply had to pop off the top of the water handle knob using a flat-head screwdriver and unscrew the screw that becomes exposed. Then slide the handle knob out so that's it's completely off and then rotate the little white plastic thingy (don't you love my use of technical terms?) slightly clockwise so that it would allow me to turn the water more towards HOT. Then slide the handle knob back on, put the screw back in and pop the top back in place. Took a total of 5 minutes to fix. Just call me MacGyver.
