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.

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)

tank/refill.
3. Open shutoff fully.
4. Remove syrup flow control form upper body
and clean out any foreign material to ensure

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. Temperature not stable
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. Dispense 10 drinks and re-check brix.
No syrup dispensed
1. Water and syrup shutoffs on mounting block
not fully open.
2. Electric current not reaching valve.
3. Improper or inadequate water or syrup sup-
ply.
4. Transformer Failure
5. Bad valve solenoid(s)
1. Open shutoff fully.
2. Check electric current supplied to valve. If
current is adequate, check solenoid coil and
switch, and replace if necessary.
3. 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
4. Reset transformer circuit breaker. If breaker
trips again check for pinched wire harness
at backblocks
5. Replace Solenoid(s)
