A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encoun-

tered.  If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service 

Department.

•  Inspection, testing, and repair of electrical equipment should be performed only by qualified service personnel.

•  All electric components have 120 volt ac voltage on their terminals. Shorting of terminals or the application of external

voltages may result in equipment failure.

•  Intermittent operation of electronic equipment is unlikely. Component failure will normally be permanent. If an inter-

mittent condition is encountered, the cause will likely be a switch contact or a loose connection at a terminal or crimp.

•  Solenoid removal requires interrupting the water supply to the valve. Damage may result if solenoids are energized

for more than ten minutes without a supply of water.

•  The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will help to

avoid twists and kinks in the tubing.

•  Make certain that all plumbing connections are sealed and electrical connections tight and isolated.

•  This brewer is heated at all times unless disconnected from the power source. Keep away from combustibles.

•  Exercise extreme caution when servicing electrical equipment.

•  Disconnect the brewer from the power source when servicing, except when electrical tests are specified.

•  Follow recommended service procedures

•  Replace all protective shields or safety notices
