A coffee grinder which has several different automatic grinding capacities is connected to a coffee brewer which has several different automatic brewing capacities by a control that inhibits brewing of all but the corresponding brew capacity following grinding of a quantity of coffee. The grinder is also inhibited from grinding any more coffee until the appropriate brew cycle of the coffee brewer is started. Once the corresponding brewing cycle is selected, the coffee grinder is reset and any grinding capacity may be selected. A calibration mode for the ...


A method for calibrating a coffee brewer for automatic operation, comprising the steps of: determining whether a control circuit for the coffee brewer is in a calibrate mode or a normal run mode; setting said control circuit to said calibrate mode if said determining step determines that said control circuit is in said normal run mode; initiating a brewing operation of the coffee brewer for a predetermined quantity of water; timing a running of said brewing operation; halting said brewing operation when said predetermined quantity of water is output from...
