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.
• Only qualified service personnel should perform inspection, testing, and repair of electrical equipment.
• Shorting the terminals or the application of external voltages to electronic components may result in component
or circuit board failure.
• Intermittent operation of electronic circuit boards is unlikely. board failure will normally be permanent. If an
intermittent condition is encountered, the cause will likely be a switch contact or a loose wire 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 avoid twists and kinks in the tubing.
• Make certain that all plumbing connections are sealed and all electrical connections are tight and isolated.
• This dispenser is heated at all times. 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.
