TROUBLE
CAUSE
REMEDY
No syrup dispensed
1.
Water and syrup shutoffs on mounting
block not fully open.
2. Electric current not reaching valve.
3.
Improper or inadequate water or syrup
supply.
4. Transformer Failure
5.
Bad valve solenoid(s)
1.
Open shutoff fully.
2. Check electric current supplied to valve.
If current is adequate, check solenoid coil
and switch, and replace if necessary.
3. Remove valve from mounting block and
open shutoffs slightly and check water and
syrup flow. If no flow, check dispenser for
freeze-up or other problems
4.
Reset transformer circuit breaker. If
breaker trips again check for pinched wire
harness at backblocks
5. Replace Solenoid(s)
Water only dispensed; no
syrup; or syrup only dispensed,
no water
1.
Water or syrup shutoff on mounting block
not fully open.
2.
Improper or inadequate water or syrup
flow.
3.
BIB supply too far from dispenser.
4.
CO
2
pressure too low.
5.
Stalled or inoperative BIB pump
6. Kinked line.
1.
Open shutoff fully.
2. Remove valve from mounting block, open
shutoffs slightly and check water and
syrup flow. If no flow, check dispenser for
freeze-up or other problems. Ensure BIB
connection is engaged.
3.
Check that BIB supply is within six (6) feet
of the dispenser.
4.
Check the CO
2
pressure to the pump
manifold to ensure it is between 70 and 80
psi (0.483 and 0.552 MPa).
5. Check CO
2
pressure and/or replace pump.
6. Remove kink or replace line.
Syrup only dispensed. No
water, but CO
2
gas dispensed
with syrup.
1.
Improper water flow to dispenser.
2. Carbonator pump motor has timed out.
1.
Check for water flow to dispenser (see
Insufficient Water Flow on previous page).
2.
Reset by turning the unit OFF and then
ON.
Excessive foaming.
1. Incoming water or syrup temperature too
high.
2. CO
2
pressure too high.
3.
Water flow rate too high.
4. Nozzle not installed correctly.
5.
Nozzle and nozzle injectors 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
Water Flow Rate & Syrup/Water Ratio”
Section.
4.
Remove and reinstall properly.
5.
Remove nozzle and clean injectors.
6.
Bleed air from BIB lines.
7.
Check quality of ice used in drink.
8. Check refrigeration system.
Warm drinks.
1.
Restricted airflow.
2. Dispenser connected to hot water supply.
3. 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. Add pre-cooler or replace with larger
dispenser.
