manual abstract
To reset press and hold CANCEL for 3 seconds, or re-energize the brewer. (Possible causes of the problem are: no incoming water; slow flow of incoming water, sensor not reading, etc.). E. Keyswitch Locked: If a key switch is depressed for 10 seconds this error message will occur. Lights will flash alternately and the brewer will turn off all valves and elements. Press and hold the CANCEL key for 3 seconds to reset the brewer (or re-energize the brewer). If the problem re-occurs this indicates a defective switch on the key pad. F. “Valve Fault”- Faulty Valve Detection: When an electric or switching problem is detected with either the inlet or brew valve the brewer turns off all elements and valves and displays “valve fault…”. All of the lights will be turned on. Before re-setting the brewer the valves must be checked to determine the problem. The brewer must be re-energized to re-set, (pressing CANCEL for 3 seconds will not reset a valve fault). 10 CLEANING INSTRUCTIONS CLEANING INSTRUCTIONS CAUTION: Burn Hazard PROCEDURE: Clean Coffee Brewer PRECAUTIONS: Disconnect brewer from electric power.

Water is heated in the tank by the heating element (15). 4. The tank lid (9) is sealed around the edge with a gasket (6), and is secured by 3 clips (10). 5. Heated water is dispensed to the brew head through the brew tube (14), brew solenoid (18), and spout of the brew fitting (19). The brew solenoid is energized during the brew cycle by the controller.
