    What to do if the FBD Beverage Dispenser shows 'Syrup Out' error #011, 012, 013, 014?
    • C
      Caitlin PageSep 7, 2025
      If the FBD Beverage Dispenser displays a 'Syrup Out' error, it indicates that the syrup pressure is less than 45 PSIG (310 kPag), especially for the base syrup in multi-flavor dispensers. Here's what you should do: * Replace the empty BIB (Bag-In-Box). * Ensure the gas line is properly connected to the BIB pump. * Check that the BIB pump is operating correctly. * Make sure the gas tank is not empty. * Verify the syrup shutoff valve at the solution module is turned on. * Confirm that any syrup shutoff valves at the back of the dispenser are not turned off. * Ensure the syrup supply pressure at the dispenser reads 70 PSIG (483 kPag), adjusting the regulator if necessary. * Check that the syrup pressure transducer is connected and working properly.

      To resolve a 'CO2 Out' error on your FBD Beverage Dispenser, replace or refill the CO2 tank. Make sure that the CO2 shutoff valve at the back of the unit isn’t turned off, and ensure the CO2 pressure transducer is connected and working properly. Finally, check that the CO2 supply pressure at the dispenser is reading 70 PSI, and adjust the regulator if needed, because CO2 pressure may be less than 45 PSI.

      To fix a 'Water Out' error on your FBD Beverage Dispenser, make sure the water line to the unit is on and the water shutoff at the solution module is turned on. Ensure the CO2 supply line is connected to the water pump and that the pump is not stalled. Verify the CO2 supply pressure at the dispenser is reading 70 PSI, adjusting the regulator if needed. Also, check that the water pressure transducer is connected and working properly, because water pressure may be less than 45 PSI.

    Why does my FBD 772 say 'Compressor Ran Too Long'?
    • R
      Ryan RoweAug 29, 2025
      If your FBD Beverage Dispenser shows 'Compressor Ran Too Long', and the location is an extreme volume venue such as a festival, contact FBD service for instructions on adjusting the timer. Otherwise, run the refrigeration diagnostic sequence to determine the reason for the failure, because the compressor may have run continuously for more than 90 minutes.
