TROUBLE
CAUSE
REMEDY
Insufficient water flow
(plain water drinks).
1. Insufficient incoming supply pressure.
2. Shutoff on mounting block not fully open.
3. Foreign debris in water flow control.
4. Water filtration problem.
1. Verify incoming supply water pressure to plain
water inlet is a minimum of 75 psi (0.516 MPa)
and a maximum of 125 psi (0.862 MPa).
2. Open shutoff fully.
3. Remove water flow control from valve and
clean out any foreign material to ensure
smooth spool movement.
4. Service water system as required.
Erratic ratio.
1. Incoming water and/or syrup supply not at
minimum flowing pressure.
2. Foreign debris in water and/or syrup flow
control.
3. CO
2
regulator malfunction.
1. Check pressure and adjust.
2. Remove flow control from suspected valve
and clean out any foreign material to ensure
smooth spool movement.
3. Repair or replace CO
2
regulator.
Insufficient syrup flow.
1. Insufficient CO
2
pressure to BIB pumps.
2. Shutoff on mounting block not fully open.
3. Foreign debris in syrup flow control.
4. Defective BIB pump.
1. Adjust CO
2
pressure to BIB pumps to 80 psi
(0.552 MPa) (min. 70 psi (0.483 MPa). Do not
exceed manufacturer’s recommendations.
2. Open shutoff fully.
3. Remove syrup flow control from valve and
clean out any foreign material to ensure
smooth spool movement.
4. Replace pump.
Valve will not shut off.
1. Debris in paddle arms.
2. Solenoid plunger sticking.
1. Activate valve a few times to free debris. Clean
out any foreign material.
2. Replace solenoid coil.
Water continually
leaking at connections.
1. Loose water connections.
2. Flare seal washer leaks.
1. Tighten water connections.
2. Replace flare seal washer.
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
shut-offs 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.
