Report "I recently moved, and when I got situated, I simply added water to the tank, plugged it in, and turned it on. While warming up, the ususal hissing noise before the pressure and temperature starts building, kept hissing for about 4-5 times the usual length of time, the pressure was at zero, but the temperature almost pegged the needle. I shut it off, as the machine had lost it's prime and would not pump any water. Later after it cooled down, I primed the pump, which is fine now, but the machine no longer heats the water or builds pressure. what do you think?"
