TROUBLE
CAUSE
REMEDY
Excessive foaming.
1.
Incoming water or syrup temperature too high.
2. CO
2
pressure too high.
3.
Water flow rate too high.
4. Nozzle and diffuser not installed.
5.
Nozzle and diffuser not clean.
6.
Air in BIB lines.
7.
Poor quality ice.
8.
High beverage temperature.
1. Correct prior to dispenser. Consider larger
dispenser or pre-cooler.
2.
Adjust CO
2
pressure downward, but not less
than 70 psi (0.483 MPa).
3.
Re-adjust and reset ratio. Refer to “Adjust Wa
-
ter Flow Rate & Syrup/Water Ratio” Section.
4. Remove and reinstall properly.
5.
Remove and clean.
6.
Bleed air from BIB lines.
7.
Check quality of ice used in drink.
8. Check refrigeration system.
Compressor starts and
continues to run until
freeze and will not cut
off.
1.
PCB malfunctioning or faulty ice bank probe.
2. Ice bank probe positioned improperly.
3.
Ice bank probe shorted to ground.
1.
Disconnect ice bank probe from PCB. If
compressor continues to run, replace PCB. If
compressor stops replace ice bank probe
2. Check positioning of ice bank probe, and
replace if needed.
3.
Replace ice bank probe.
Warm drinks.
1.
Restricted airflow.
2.
Dispenser connected to hot water supply.
3.
Refrigeration system not running.
4. Refrigerant leak.
5. Condenser fan motor not working.
6. Dirty condenser.
7. Dispenser capacity exceeded.
1.
Check clearances around sides, top, and
inlet of unit. Remove objects blocking airflow
through grill.
2.
Switch to cold water supply.
3.
Refer to pages 16-17, the correct relay will
cause compressor failure.
4. Repair and recharge.
5.
Replace condenser fan motor.
6. Clean condenser.
7. Add pre-cooler or replace with larger dispenser.
Compressor does not
start (no hum), gas
cooler fan does not run,
and no ice bank.
1.
There is a five (5) minute compressor and
condenser fan delay.
2.
Ice bank probe not completely submerged.
3.
Circuit breaker or fuse tripped.
4. Inadequate Voltage
5.
PCB malfunctioning
6. Incorrect Wiring
7.
Faulty ice bank probe.
8.
Transformer failure.
9.
Ice bank probe not connected properly to PCB.
1.
Allow for five (5) minute delay to lapse.
2.
Fill water reservoir until water flows from over
-
flow tube.
3.
Reset breaker or replace fuse. If problem per
-
sists: Determine reason and correct or electri
-
cal circuit overloaded; switch to another circuit.
4. Measure voltage across common and run
terminal on compressor. Voltage must not drop
below 90% of rated voltage.
5.
Replace PCB Assembly.
6.
Refer to wiring diagram and correct.
7.
Replace ice bank probe.
8.
Reset transformer circuit breaker. If
breaker pops again, refer to “Circuit breaker
tripping” in Troubleshooting.
9.
Connect ice bank probe to PCB.
