SOLUTION
Nothing Dispenses
When Valve Activated
A. Circuit Board
malfunctioning
B. Soda & front
syrup solenoid wires
plugged into wrong
connector.
C. Water solenoid
malfunctioning.
D.Water Solenoid
Core defective
E. Circuit board
malfunctioning.
F. Circuit board
misaligned. Lever not
making contact with
circuit board sensor.
A. Programmer does not light up 24 volt
supply connected. NOTE: For Valves
made on/after Nov 2011, the amber
(orange) LED does not light up AND the
24 VOLT supply is connected.
B. ‘5 sec water’ button on programmer
dispenses small amount of syrup. Green
and red LEDs light up.
C. Programmer lights up, but does not
dispense water with ‘5 sec water’. Shut-
offs are open. Green LED lights up.
D. Rubber poppet in core is swollen or
deformed. Green LED lights up.
E. New ratio cannot be entered w/
programmer.
F. Circuit board not screwed all the way
down. Board misaligned with holes and
mounting posts.
A. Check fuser, or replace circuit
board.
B. Connect soda and front syrup to
correct connectors.
C. Replace water solenoid.
D. Replace core.
E. Replace circuit board.
F. Ensure board is aligned & screw in
board all the way down.
