interface board and keypad
PCB

Remedy
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.
B. Unplugging the unit and performing a
power up will re-synchronize the lighting
sequence.
A. Turn the keyswitch to disconnect
power at the interface boards. Check
harness connections at each interface
board.
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. 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. Replace keypad circuit board and
ribbon cable.
E. Replace the main control board.
Check the programming of each keypad
and set each button as CW, PW, or
timed dispense based upon the flavor
