ABSTRACT:
A coffee making machine of the type adapted to be connected to a mains water supply is provided with a reservoir having a level sensor controlling the water refill valve to the reservoir, and a heating element which is thermostatically controlled, the refill valve and the thermostat both being controlled by a single modular replaceable solid state circuit board. The level sensor functions to cause refill of the reservoir to the appropriate level for subsequent brewing of a full pot of coffee, irrespective of the mains water pressure and the route by which water may previously have been removed from the reservoir. The electronically controlled thermostat allows only small drops in temperature, e.g. 3.degree. F., before operating to reheat the water in the reservoir. The water can accordingly be stored at closer to the boiling point and delivered to contact coffee for brewing purposes at temperatures of not less than 200.degree. F.
