TROUBLE
CAUSE
REMEDY
Water leakage around
nozzle.
1.
O-ring not properly installed above diffuser
2.
O-ring is damaged or missing.
1.
Install or replace o-ring correctly.
2.
Replace o-ring.
Leakage between upper
and lower bodies.
1. Gap between upper and lower valve bodies.
2. Worn or damaged paddle arm assemblies.
3. Cracked valve bodies
1. Tighten all six (6) retaining screws.
2. Replace paddle arm assemblies.
3. Replace Valve Body.
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.
Insufficient 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.
1. Check pressure and adjust
2.
Remove flow controls from upper body and
clean out any foreign material to ensure
smooth free spool movement.
No product dispensed
1.
Water and syrup shut-offs on mounting block
not fully open.
2. The key switch on an electric valve is in the
OFF position.
3. Cup lever arm or ID panel actuator on electric
valve is not actuating the switch.
4. Electric current not reaching valve.
5. Improper or inadequate water or syrup supply.
6. Transformer Failure
7. Bad valve solenoid(s)
1.
Open shutoff fully.
2. Turn key switch to ON position.
3. Repair
4. Check electric current supplied to valve. If
current is adequate, check solenoid coil and
switch, and replace if necessary.
5. Remove valve from mounting block and open
shut-offs slightly and check water and syrup
flow. If no flow, check dispenser for freeze-up
or other problems
6. Reset transformer circuit breaker. If breaker
trips again check for pinched wire harness at
back-blocks
7. Replace Solenoid(s)
