TROUBLESHOOTING
TROUBLE
CAUSE
REMEDY
Insufficient water flow.
1. Insufficient incoming supply water
pressure.
2. Shutoff not fully open.
3. Foreign debris in water pump strainer
1. Verify incoming supply water pressure is a
minimum of 25 psi (0.172 MPa).
2. Open shutoff fully.
3. Remove water pump strainer and clean.
Insufficient syrup flow.
1. Insufficent CO
2
pressure to BIB pumps.
2. Out of CO
2
.
3. Shutoff not fully open.
4. Bad syrup pump.
1. Adjust CO
2
pressure to 80 Psi (0.550 MPa)
[minimum 70 Psi (0.480 MPa)] for BIB
pumps.
2. Replace CO
2
tank/refill.
3. Open shutoff fully.
4. Replace BIB pump.
Water only dispensed; no syrup;
or syrup only dispensed, no water
1. Water or syrup shutoff on mounting block
not fully open.
2. BIB supply too far from dispenser.
3. CO
2
pressure too low.
4. Stalled or inoperative BIB pump
5. Kinked line.
1. Open shutoff fully.
2. Check that BIB supply is within six (6) feet
of the dispenser.
3. Check the CO
2
pressure to the pump man-
ifold to ensure it is between 70 and 80 Psi
(0.483 and 0.552 MPa).
4. Check CO
2
pressure and/or replace pump.
5. Remove kink or replace line.
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.
1. Correct prior to dispenser. Consider larger
dispenser or pre-cooler.
2. Adjust CO
2
pressure downward, but not
less than 70 Psi.
3. Re-adjust and reset ratio.
4. Remove and reinstall properly.
5. Remove and clean.
6. Bleed air from BIB lines.
7. Check quality of ice used in drink.
Warm drinks.
1. Dispenser was recently installed.
2. Dispenser connected to hot water supply.
1. It may take up to 5 hours, after install, to
reach the desired temperature.
2. Switch to cold water supply.
No carbonation
1. Carbonator motor not running.
2. Absence of CO
2
gas.
3. Gas only from valves.
4. Carbonator tank air bound.
5. CO
2
gas pressure below too low.
6. Carbonator motor running continuously.
1. Check power supply. Be sure toggle switch
is in ON position.
2. Replace with full tank of CO
2
gas.
3. Check for power failure. Check fuses.
Clean strainer on pump.
4. Relieve gas pressure in tank by pulling ring
on safety relief valve until water spurts out.
5. Reset high pressure CO
2
gas regulator to
90-110 psi. Change CO
2
tank if required.
6. Check switch on carbonator. Check water
in check valve for blockage. Check
carbonator control. Check carbonator
pump for efficiency.
