My Cuisinart DCC-1200 Series coffeemaker suddenly won't let me program the auto-on feature anymore. I can set time of day, then program auto-on time -- but then when I turn the knob back to the Auto-on position, it's not the current time that shows, but the time I just set for it to Auto-on. It's worked perfectly for about 5 years, so this is a new problem. Is there any hope?
