I'm wondering about the difference between brew mode and keep warm mode in drip coffee makers. After my Black and Decker 2020B finishes brewing, it keeps the heating element warm for 2 hours. Is that different than if it had simply continued to brew for 2 hours?
If I want to reheat my coffee after the keep warm period has ended, is there anything wrong with simply turning it on to brew? Would that be the same as the keep warm period and thus be fine, or would it cause the heating element to behave differently and possibly burn the coffee or cause a fire hazard?
