The display on my KCM0802 pour over coffee maker flashes and doesn't brew. According to the manual it should do that only when there is no water in the reservoir, but in this case there is enough water for 6 cups, yet is still flashes and doesn't brew. I've already waited a while and after a couple of times waiting for over 10 minutes with no results I unplugged it to see if it would somehow reset itself, but to no vail. Nothing worked. Help please.
