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
¥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 Ð
¥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
Problem | Probable Cause |
Brew cycle will not start | 1. No water |
| 2. No power or incorrect voltage to |
| the brewer |
| 3. External Strainer/Flow Control |
