Although I have a 195, I haven't done that myself yet. I know the valves are under the fridge, I've taken off the panel where the doggy bowl is, and seen them. That's all I know at the moment cause my dealer dewinterized it for me. But just because you have water coming out of the hot side, does NOT mean you have hot water in the tank. If you are not hooked up to city water supply, turn on the water pump till it pressurizes, or if you are hooked up to city water, then go pull the pressure release on the h/w tank and see if water squirts out. If it doesn't squirt, you have no water in the tank. Hopefully you do or you might have burned out the electrical element.
