Cevap: Not heating correctly - incomplete perkWe've had a 12-cup Hamilton Beach for quite a few years and it quit perking at the desired length of time a while back. I've been pouring hot water through the basket to make coffee for a while, what a pain. Taking a cue from Zenon I got my Dremel out and using a small wire brush and various other grinding implements I cleaned/shined the heating element in the bottom of the pot including the large thimble shaped opening in the bottom. I filled with water and plugged it in with the basket and tube in place and it perked for 12 minutes and the water temp was measured at 185 deg. Thanks for pointing out a simplified way of "fixing" the thermostat.
