TROUBLESHOOTING
IMPORTANT: Only qualified personnel should service internal components or electrical wiring.
WARNING: If repairs are to be made to a product system, remove quick disconnects from the
applicable product tank, then relieve the system pressure before proceeding. If repairs are to be
made to the CO
2
system, stop dispensing, shut off the CO
2
supply, then relieve the system
pressure before proceeding. If repairs are to be made to the electrical system, make sure
electrical power is disconnected from the unit or the key switch has been turned off.
Should your unit fail to operate properly, check that there is power to the unit and that the hopper
contains ice. If the unit does not dispense, check the following chart under the appropriate symptoms to
aid in locating the defect.
Contact your local syrup or beverage equipment distributor for additional information and troubleshooting
of beverage system.
Troubleshooting the LED Lighting on Customer Interface Keypad (see page 19)
Symptom Cause Remedy
1 Bonus Flavor Icon and/
or Drink Icon LEDs (see
FIGURE 3) are ON
continuously with four
quick flashes every 30
seconds.
A. This indicates a poor
connection in the lighting
synchronization harness
that connects the interface
boards together.
A. Turn the keyswitch to disconnect
power to the interface boards. Check the
electrical connections between the
harnesses that interconnect the right
side of all interface boards together. Turn
back the keyswitch to reconnect power.
2 Bonus Flavor Icon and/
or Drink Icon LEDs (see
FIGURE 3) are not in
sync with the lighting
sequence,
B. This may result over time
as the lighting sequence
between push button pads
can become slightly out of
synchronization.
B. Unplugging the unit and performing a
power up will re-synchronize the lighting
sequence.
3 Keypad LED lighting is
not working
A. Poor connection between
interface board and keypad
PCB
A. Turn the keyswitch to disconnect
power at the interface boards. Check
harness connections at each interface
board.
B. Keypad LED's are burnt
out
B. Turn the keyswitch to disconnect
power at the interface boards. Unplug
the ribbon cable from one interface
board and test it by plugging it into the
neighboring interface board. If the
keypad still doesn't light up replace the
keypad PCB.
C. Interface board is
defective.
C. Turn the keyswitch to disconnect
power at the interface boards. Unplug
the ribbon cable from one interface
board and test it by plugging it into the
neighboring interface board. If the LED's
light up the interface board is defective.
Replace the interface board.
D. Corrosion at connector
between keypad and ribbon
cable.
D. Replace keypad circuit board and
ribbon cable.
E. Main control board is
defective.
E. Replace the main control board.
4 During standby mode,
the brand and bonus
LED icons do not
alternate back and forth
- instead they light
together.
Bonus buttons are
incorrectly programmed as
brand buttons, or vice versa.
Check the programming of each keypad
and set each button as CW, PW, or
timed dispense based upon the flavor
lineup.
