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 qualied 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 ttings 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 specied. The
red “Power LED” on the door indicates that the unit is connected to AC Power.
Follow recommended service procedures.
