    How to resolve 'High Barrel Pressure' on FBD 772 Beverage Dispenser?
    • W
      Wendy GoldenAug 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 fix 'Low regulated CO2 PSI' on FBD 772?
    • A
      Ashley ColemanAug 27, 2025
      If you encounter a 'Low regulated CO2 PSI' error on your FBD Beverage Dispenser, make sure the CO2 supply is not low. Check the “carbonation” regulator on the header tray and ensure it is set to 60 PSI, because the regulated CO2 pressure may have dropped below 50 PSI.

    What does 'Hot Product Detected' mean on my FBD 772 Beverage Dispenser?
    • C
      Crystal CochranAug 27, 2025
      If your FBD Beverage Dispenser is displaying 'Hot Product Detected', check the return temperature sensor for proper operation. If hot product was detected, call FBD for technical assistance, because product in a barrel may exceed 85°F.

    What to do if FBD 772 Beverage Dispenser shows 'Safety Fill Error'?
    • S
      Sharon WintersAug 28, 2025
      To address a 'Safety Fill Error' on your FBD Beverage Dispenser, run the fill diagnostic sequence to determine the reason for the failure, because a barrel may have filled continuously for more than two minutes.

    How to troubleshoot 'Beater Low Error' on FBD Beverage Dispenser?
    • W
      wilcoxzacharyAug 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.

    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.

    What to do if my FBD 772 displays 'Board Failure'?
    • L
      longkaylaAug 30, 2025
      If your FBD Beverage Dispenser is showing a 'Board Failure', cycle the power to the unit to see if it will clear the error. If not, replace the control board, because the control board may not be functioning properly.
