Abstract
A coffee brewing machine utilizes an insulated carafe to receive the brewed coffee and automatically turns itself off a short time after completion of a brew cycle. The machine also turns off automatically a specified time after a brew cycle is initiated when calcification is so extreme that flow of water through the unit is totally prevented. Additionally, as a safety feature, the system also turns off automatically in the case of a "dry run", that is, a short specified time after accidental energization when no water is in the reservoir. A lamp is lighted when a brew cycle is in progress but is extinguished at other times.
