Black & Decker 8 cup programable thermal carafe

I love the size of this coffee maker. As I never need to make more than 6 or 8 cups, it's perfect. Good looking, shiny and sleek. However, once the coffee maker shuts off, the carafe doesn't keep the coffee hot for more than half and hour. The lid and the basket go right in the dishwasher, but the carafe does not, As the carafe is narrow at the top, it's hard to really get inside and scrub it out.
