Install or replace o-ring correctly.2. Replace o-ring.Leakage between upperand lower bodies.1. Gap between upper and lower valve bodies.2. Worn or damaged paddle arm assemblies.3. Cracked valve bodies1. 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 screws2. Replace or adjust appropriate o-ringsInsufficient 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 strainer1. Verify incoming supply water pressure is aminimum of 25 psi (0.172 MPa).2. Open shutoff fully.3. Remove water flow control from upper bodyand clean out any foreign material to ensuresmooth free spool movement.4. Remove water pump strainer and clean.Insufficient syrup flow. 1. Insufficient CO2 pressure to BIB pumps.2. Out of CO2 .3. Shutoff on mounting block not fully open.4. Foreign debris in syrup flow control.5. Bad syrup pump.1. Adjust CO2 pressure to 80 psi (0.550 MPa)[minimum 70 psi (0.480 MPa)] for BIB pumps.2. Replace CO2 tank/refill.3. Open shutoff fully.4.

Remove flow controls from upper body andclean out any foreign material to ensuresmooth free spool movement.No product dispensed 1. Water and syrup shutoffs on mounting blocknot fully open.2. The key switch on an electric valve is in theOFF position.3. Cup lever arm or ID panel actuator on electricvalve is not actuating the switch.4. Electric current not reaching valve.5. Improper or inadequate water or syrup supply.6. Transformer Failure7. Bad valve solenoid(s)1. Open shutoff fully.2. Turn key switch to ON position.3. Repair4. Check electric current supplied to valve. Ifcurrent is adequate, check solenoid coil andswitch, and replace if necessary.5. Remove valve from mounting block and openshutoffs slightly and check water and syrupflow. If no flow, check dispenser for freeze-upor other problems6. Reset transformer circuit breaker. If breakertrips again check for pinched wire harness atback blocks7. Replace Solenoid(s)
