TROUBLE
CAUSE
REMEDY
Water only dispensed, no
syrup. Or syrup only dispensed,
no water.
1. Syrup BIB empty.
2.
Water or syrup shutoff on mounting block
not fully open.
3.
Improper or inadequate water or syrup
supply.
4. CO
2
pressure to syrup pump too low.
5. Stalled or inoperative BIB pump.
6.
Kinked line.
7. CO
2
regulator malfunction.
1.
Replace syrup BIB as required.
2.
Open shutoff completely.
3.
Remove valve from mounting block &
open shutoffs slightly. Check water &
syrup supply. If no supply, check unit for
other problems. Ensure BIB connection is
engaged.
4. Check the CO
2
pressure to the pump to
ensure it is between 70-80 PSI (0.483-
0.552 MPA).
5. Check CO
2
pressure and/or replace pump.
6. Remove kink or replace line.
7.
Repair or replace CO
2
regulator as
required.
Syrup only dispensed. No
water, but CO
2
gas dispensed
with syrup.
1.
Improper water flow to dispenser.
2. Carbonator pump motor has timed out.
3.
Liquid level probe not connected properly
to PCB.
4. Defective PCB assembly.
5.
Defective liquid level probe.
6.
Weak or defective carbonator pump.
1.
Check for water flow to dispenser.
2.
Reset by turning the unit OFF, then ON
by using the circuit breaker on the power
supply or momentarily unplugging unit.
3.
Check connections of liquid level probe to
PCB assembly.
4.
Replace PCB assembly.
5.
Replace liquid level probe.
6. Replace pump.
Excessive foaming.
1. No ice in bin.
2. Incoming water or syrup temperature too
high.
3. CO
2
pressure too high.
4.
Water flow rate too high.
5.
Nozzle and diffuser not clean.
6.
Air in BIB lines.
1. Fill bin with ice and allow coldplate to
re-stabilize.
2. Correct prior to dispenser.
3. Adjust CO
2
pressure downward, but not
less than 70 PSI (0.483 MPA).
4.
Re-adjust and reset ratio.
5.
Remove and clean.
6.
Bleed air from BIB lines.
Circuit breaker tripping.
1.
Valve wire harness shorted to itself or
faucet plate
2. Controller PCB is bad.
3. Secondary wire harness has a short.
4. Power supply is bad.
1. 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 next step.
2. 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-pin harness and proceed to
next step.
3. Locate short from a motor or solenoid
harness and replace.
4. Detect short by disconnecting all
harnesses connected to power supply.
Restore power. If breaker still trips, replace
power supply.
