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
shut offs slightly. Check water & syrup sup
-
ply. If no supply, check unit for other prob-
lems. 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 cold plate 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.
Low or no carbonation.
1.
Low or no CO
2
.
2.
Low water pressure.
3.
Worn or defective carbonator pump.
4.
Backflow preventer not allowing water to
flow.
5.
Probe malfunctioning.
6. PCB malfunctioning.
1. Check CO
2
supply. Adjust CO
2
pressure to
70 psi (0.483 MPa).
2.
Need water booster kit.
3. Replace carbonator pump.
4.
Replace backflow preventer, noting the flow
direction arrow from pump to cold plate.
5.
Replace probe.
6. Replace PCB.
Erratic ratio.
1.
Incoming water and/or syrup supply not at
minimum flowing pressure.
2.
Foreign debris in water and/or syrup flow
control.
3. CO
2
regulator malfunction.
1. Check pressure and adjust.
2.
Remove flow control from suspected valve
and clean out any foreign material to ensure
smooth spool movement.
3. Repair or replace CO
2
regulator.
