TROUBLE
CAUSE
REMEDY
Water only dispensed; no
product; or product only
dispensed, no water
1. Water or product shutoff on mounting block
not fully open.
2.
Improper or inadequate water or product
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 man-
ifold 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.
Circuit breaker tripping.
1. Valve wire harness shorted to itself or to
faucet plate.
2. PCB is bad.
3. Secondary wire harness is bad.
4. Transformer failure.
1. Detect short by disconnecting input
fastener to keylock and single pin
connector. Restore power if breaker
doesn’t trip. Then valve wire harness is
shorted. If OK, reconnect.
2. Detect short by disconnecting J1
connector (24 VAC input) from PCB.
Restore power, if breaker doesn’t trip.
Then replace PCB. If breaker does trip,
then PCB is OK. Reconnect J1 connector.
3. If it does not trip, locate short in secondary
harness between transformer, PCB, and
valve wire harness.
4. Detect short by disconnecting both
transformer fasteners and restore power. If
breaker does trip, replace transformer.
