Not sure what I did wrong. I set the temperature and the timer and started the machine. It was set to run for 2 hours.
When I returned about 4 hours later the timer was down to 00:00 but the temperature was still at 150º F and the water was still circulating.
I thought that when the time expired the water temperature would also begin to cool. That way nothing would overcook.
What am I not understanding?
