ISSUE
CAUSE
SOLUTION
3.18 Syrup only dispensed. No water, but
CO2 gas dispensed with syrup.
A. Improper water flow to dispenser.
B. Carbonator pump motor has timed out
(display message on the LCD screen).
C. Liquid level probe not connected
properly to PCB.
D. Defective PCB assembly.
E. Defective liquid level probe.
F. Weak or defective carbonator pump.
A. Check for water flow to dispenser.
B. Reset by turning the unit OFF, then ON
by using the circuit breaker on the
power supply or momentarily unplugging
unit.
C. Check connections of liquid level
probe to PCB assembly.
D. Replace PCB assembly.
E. Replace liquid level probe.
F. Replace pump.
3.19 Excessive foaming.
A. No ice in bin.
B. Incoming water or syrup temperature
too high.
C. CO2 pressure too high.
D. Water flow rate too high.
E. Nozzle and diffuser not clean.
F. Air in BIB lines.
A. Fill bin with ice and allow coldplate
to re-stabilize.
B. Correct prior to dispenser.
C. Adjust CO2 pressure downward, but
not less than 70 PSI.
D. Re-adjust and reset ratio.
E. Remove and clean.
F. Bleed air from BIB lines.
3.20 Circuit breaker tripping.
A. Valve wire harness shorted to itself
or faucet plate.
B. Controller PCB is bad.
C. Secondary wire harness has a short.
D. Power supply is bad.
A. Detect short by disconnecting valve
harnesses from switch panel (4 25-pin
harnesses and 4 9-pin harnesses).
Restore power. If breaker does not trip,
find and replace shorted harness. If
breaker trips, re-install the 8 harnesses,
and proceed to step B.
B. Detect by disconnecting the white
5-pin harness from the controller PCB.
Restore power. If breaker does not trip,
replace controller PCB. If breaker trips,
re-install the white 5-in harness and
proceed to step C.
C. Locate short from a motor or solenoid
harness and replace.
D. Detect short by disconnecting all
harnesses connected to power supply.
Restore power. If breaker still trips,
replace power supply.
