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
restabilize.
2. Correct temperature prior to reaching
dispenser.
3. Adjust CO
2
pressure downward, but not less
than 70 psi (0.483 MPa).
4. 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.

Push chute, ice door
opens, motor runs, but
ice does not dispense,
or ice is of poor quality.
1. Dispenser is out of ice.
2. Agitator pin is missing or damaged.
3. Poor ice quality.
4. Key not installed on agitation shaft.
1. Fill dispenser with ice.
2. Replace agitator pin.
3. Service ice machine.
4. Install key onto agitation shaft.
Noisy/cavitating
carbonator pump.
1. Insufficient incoming water supply pressure. 1. Verify incoming supply water pressure to
carbonator pump is a minimum of 75 psi (0.516
MPa), or maximum of 125 psi (0.862 MPa).
