TROUBLESHOOTING

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

encountered. 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 intermittent 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.

WARNING

• 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
