    How to resolve 'High Barrel Pressure' on FBD 773?
    • M
      mackmitchellAug 26, 2025
      To troubleshoot a 'High Barrel Pressure' error on your FBD Beverage Dispenser, dispense a drink to reduce the barrel pressure. If set to the ON mode, the unit will refreeze. Run the fill diagnostic if a failed component is suspected. Check the “Active Charge” regulator located on the product header to ensure it is set at 30 PSI. Make sure all barrels should be fully depressurized before checking the active charge, because pressure on a barrel may have exceeded 55 PSI.

    How to troubleshoot 'Beater Low Error' on FBD 773 Beverage Dispenser?
    • J
      James JohnsonAug 28, 2025
      To address a 'Beater Low Error' on your FBD Beverage Dispenser: 1. Check the brix in the barrel. If low, check the brix at the sample valve and adjust if needed. 2. Drain and refill the barrel. 3. Check the fault code history for multiple sold out errors within a short period. This can mean that the BIB connector or syrup pump has a suction leak. Fix if necessary. 4. Run the beater circuit diagnostic if a component failure is suspected, because the beater motor may have stalled during operation.

      Sarah ShortAug 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.
