TROUBLE
CAUSE
REMEDY
No product when valve
is activated.
1. Keyswitch is off or keyswitch harness is
disconnected.
2. No power to dispenser.
3. Malfunctioning switch assembly.
4. Malfunctioning power supply.
5. Malfunctioning PCB board.
6. Malfunctioning LEV valve.
1. Turn keyswitch on and/or reconnect keyswitch
harness.
2. Check internal breaker and incoming power.
3. Replace switch assembly.
4. Check voltage to power supply. Check fuses.
5. Replace PCB board.
6. Replace valve.
Water only dispensed,
no syrup. Or syrup only
dispensed, no water.
1. Syrup BIB empty.
2. Water or syrup shutoff on mounting block not
fully open.
3. Improper or inadequate water or syrup supply.
4. CO
2
pressure to syrup pump too low.
5. Stalled or inoperative BIB pump.
6. Kinked line.
7. CO
2
regulator malfunction.
1. Replace syrup BIB as required.
2. Open shutoff completely.
3. Remove valve from mounting block & open
shutoffs slightly. Check water & syrup supply.
If no supply, check unit for other problems.
Ensure BIB connection is engaged.
4. Check the CO
2
pressure to the pump to ensure
it is between 70-80 PSI (0.483-0.552 MPA).
5. Check CO
2
pressure and/or replace pump.
6. Remove kink or replace line.
7. Repair or replace CO
2
regulator as required.
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.
3. Liquid level probe not connected properly to
PCB.
4. Defective PCB assembly.
5. Defective liquid level probe.
6. Weak or defective carbonator pump.
1. Check for water flow to dispenser.
2. Reset by turning the unit OFF, then ON by
using the circuit breaker on the power supply or
momentarily unplugging unit.
3. Check connections of liquid level probe to PCB
assembly.
4. Replace PCB assembly.
5. Replace liquid level probe.
6. Replace pump.
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 re-stabi-
lize.
2. Correct prior to dispenser.
3. Adjust CO
2
pressure downward, but not less
than 70 PSI (0.483 MPA).
4. Re-adjust and reset ratio.
5. Remove and clean.
6. Bleed air from BIB lines.
Off Taste in Soda.
1. Leaking water check valve, allowing carbonat-
ed water to back into supply line.
1. Dismantle and clean check valve. Replace
O-ring, if torn or distorted.
Valves inoperable.
1. Loss of Power.
1. Check power supply to see if plugged in. Check
transformer circuit breaker. Check main power
circuit breaker, 110V.
