TROUBLESHOOTING
TROUBLE CAUSE REMEDY
Water leakage around nozzle. 1. O-ring is damaged or missing. 1. Replace o-ring.
Miscellaneous leakage. 1. Gap between parts.
2. Damaged or improperly installed o-rings. 1. Tighten appropriate retaining screws
2. Replace or adjust appropriate o-rings
Insufficient water flow. 1. Insufficient incoming supply water
pressure.
2. Shutoff on mounting block not fully open.
3. Foreign debris in water flow control.
4. 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 flow control from upper
body and clean out any foreign material to
ensure smooth free spool movement.
4. Remove water pump strainer and clean.
Insufficient syrup flow. 1. Insufficent CO
2
pressure to BIB pumps.
2. Out of CO
2
.
3. Shutoff on mounting block not fully open.
4. Foreign debris in syrup flow control.
5.
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. Remove syrup flow control form upper
body and clean out any foreign material to
ensure smooth free spool movement.
5. Replace BIB pump.
Erratic ratio. 1. Incoming water and/or syrup supply not at
minimum flowing pressure.
2. Foreign debris in water and/or syrup flow
controls.
3. Tolerance of parts afffecting ratio.
4. Flowmeter issues.
1. Check pressure and adjust
2.
Remove flow controls from upper body and
clean out any foreign material to ensure
smooth free spool movement.
3. Offset ratio value to obtain optimum
dispense ratio.
4. Replace valve body.
No syrup dispensed, only water
dispensed
1. Out of syrup
2.
Water and syrup shutoffs on mounting
block not fully open.
3. Electric current not reaching valve.
4. Improper or inadequate water or syrup
supply.
5. Transformer Failure
6. Bad valve solenoid(s)
7. Core seal defective
8. Coil defective
1. Replace BIB.
2.
Open shutoff fully.
3. Check electric current supplied to valve.
If current is adequate, check solenoid coil
and switch, and replace if necessary.
4. 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
5. Reset transformer circuit breaker. If
breaker trips again check for pinched wire
harness at backblocks
6. Replace Solenoid(s)
7. Replace core seal assembly, if rubber has
expanded.
8. Verify connectors are locked into sockets
on circuit board OR replace coil if
resistance is open or shorted.
