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 person-
nel.
•  All electronic components have 120 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 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.  Keep away from combustibles.
WARNING –  •  Exercise extreme caution when servicing electrical equipment.
 
  •  Unplug the brewer when servicing, except when electrical tests are specified.
 
  •  Follow recommended service procedures
 
  •  Replace all protective shields or safety notices
