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 electronic components have 120 - 240 volt ac and low voltage dc potential on their terminals.
Shorting of terminals or the application of external voltages may result in 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 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 electrical connections tight and isolated.
This brewer 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.
