Bunn single sh brewwise dbc Guía De Operación

Page 39

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 per-

manent.  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 sole-

noids 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 iso-

lated.

 

• 

This brewer is heated at all times. Keep away from combustibles. 

  

 

• 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.
