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.
