When a particular name of coffee is ground into the
Smart Funnel, that name and the batch size selected
are transferred from the grinder to the programming
CHIP located in the funnel handle. The funnel is then
inserted into the brewer’s funnel rails. The SENSING
COIL on the brewer reads the information contained in
the handle. The name of the coffee flavor will then ap-
pear on the display. This allows the operator to set the

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 120-240 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 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.

PROBLEM
PROBABLE CAUSE
REMEDY
Inconsistent beverage level in
server/dispenser
1.
Improper water pressure
Check operating water pressure to
the brewer. It must be between 20
and 90 psi (138 and 620 kPa).
2.
Brew valve
Test the brew valve. Refer to test
outputs on page 48. Turn the valve
on for 30 seconds and collect the
water dispensed from the spray-
head. Repeat the test several times
to confirm a consistent volume of
dispensed water. If not consistent,
check the valve, tubing and spray-
head for lime buildup.
3.
Bypass valve
If bypass is being used on the in-
consistent brewing recipe, test the
bypass valve. Refer to test outputs
on page 48. Turn the valve on for
30 seconds and collect the water
collected from the funnel. Repeat
the test several times to confirm
a consistent volume of dispensed
water. If not consistent, check the
valve, tubing and fittings for lime
buildup.

5.
Lime buildup
Inspect for lime buildup that could
block the tank, tank fittings, tubing,
valves and sprayhead.
Brew volume adjustment
Adjust the brew volume, calibrate
sprayhead and bypass as required
to achieve the desired volume for
each brew cycle.
