Bunn ICB Guía Del Usuario

Page 55

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 qualifi ed service person-
nel.

•  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 fi ttings 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 specifi ed.

 

  •  Follow recommended service procedures.

 

  •  Replace all protective shields or safety notices.
