TROUBLE
CAUSE
REMEDY
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.
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 coldplate.
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.
Insufficient soda flow
(carbonated drinks).
1.
Insufficient CO
2
supply pressure.
2.
Shutoff on mounting block is not fully open.
3.
Foreign debris in soda flow control.
1. Verify incoming CO
2
pressure is between
70 PSIG (0.483 MPA) and 80 PSIG (0.552
MPA)
2.
Open shutoff fully.
3.
Remove soda flow control from valve and
clean out any foreign material to ensure
smooth spool movement.
Insufficient water flow (plain
water drinks).
1.
Insufficient incoming supply pressure.
2.
Shutoff on mounting block not fully open.
3.
Foreign debris in water flow control.
4.
Water filtration problem.
1.
Verify incoming supply water pressure to
plain water inlet is a minimum of 50 PSI
(0.345 MPA) and a maximum of 100 PSI
(0.689 MPA).
2.
Open shutoff fully.
3.
Remove water flow control from valve and
clean out any foreign material to ensure
smooth spool movement.
4.
Service water system as required.
Insufficient syrup flow.
1.
Insufficient CO
2
pressure to BIB pumps.
2.
Shutoff on mounting block not fully open.
3.
Foreign debris in syrup flow control.
4.
Defective BIB pump.
1. Adjust CO
2
pressure to BIB pumps to 80 PSI
(0.552 MPA) (min. 70 PSI (0.483 MPA). Do
not exceed manufacturer’s recommenda-
tions.
2.
Open shutoff fully.
3.
Remove syrup flow control from valve and
clean out any foreign material to ensure
smooth spool movement.
4.
Replace pump.
