Install a taste and odor filter in water supply, and replace cartridges regularly. Use a quality coffee with a consistent roast. Use proper grind and amount of coffee per brew. 12 CAUTION ELECTRIC SHOCK HAZARD Live electrical circuits may be exposed while performing these procedures. These procedures are to be performed by qualified technical personnel only. ERROR DETECTION 13 WHAT TO CHECK DESCRIPTION CORRECTIVE ACTION Has the water tank been properly filled? On initial startup, an attempt to heat a dry tank will be detected as too high a temperature or insufficient temp rise, or will trip the high limit. Tank must be properly filled as detailed on page 6. Check hi-limit (see below) Has hi-limit safety thermostat tripped off? Brewer may have been started without water in the tank, or the temp control thermostat may require adjustment. Access hi-limit by removing front panel. Hi-limit is on the left side of the tank. Use an insulated tool to push the red button in until it “clicks” and stays. Reset per above. Check control board and temp probe. Brewer will go into error mode immediately if either the control board or temp probe is defective. Temp probe electrical resistance is approximately 30K. at room temp, and 2K. at boiling. Replace temp probe if less than 1K.. Reset by holding the CANCEL key for 3 seconds. If lights continue to flash: Disconnect temp probe from control board. a. If lights continue to flash, unplug brewer and replace control board. b. If lights stop flashing, unplug brewer and replace temp probe. Check power board and heating element.. Brewer will go into error mode 4 minutes after energizing the heating element if insufficient heat rise is detected. The heating element is energized by an electronic power board, and protected by the hi-limit safety. Heating element should receive full line voltage (i.e. 120V, 208V or 240V). Be sure the hi-limit safety is reset. Reset by holding the CANCEL key for 3 seconds. If lights resume flashing after 4 minutes: Check the voltage across the heating element terminals: a. If no voltage is present, unplug brewer and replace power board. b. If proper voltage is present, unplug brewer and replace tank heating element. Is the brew temperature properly adjusted? The brewer may occasionally go into error mode if the brew temperature is set too high. See page 15 for temperature adjustment procedure. This brewer is designed to perform a continuous internal diagnosis, and to signal faults by flashing all the lights. In fault mode, warmers, heating element and water fill solenoid are turned “off”, and most keypad functions are disabled. Error detection (all lights flashing) will occur under two conditions: • Anytime a temperature in excess of 214.F is detected. • Temperature does not change by at least 2.F within 4 minutes of tank heater being energized (HEAT light on). To reset the brewer after the fault has been corrected, press and hold the CANCEL key for 3 seconds, or disconnect the brewer from electrical power for three seconds.
