Why is my FBD FBD553D Beverage Dispenser drink too 'wet'?
- T
  Tracey GonzalezDec 1, 2025
  If your drink is too 'wet' from the FBD Beverage Dispenser, defrost and make sure the chamber is 90% full. Clean or replace the CO2 check valve if it's clogged. Activate the "CO2 Sol" in “Manual On/Off” and check for 24VAC at the coil; clean or replace the solenoid if necessary. Ensure the CO2 level in the drink is adequate by raising "Reg.CO2" within the 28-32 psi range for both chambers or lowering the level control settings for one chamber. Check the secondary regulator, repair or replace if necessary. Check the "Reg'd CO2" in readouts and compare it with the regulator gauge; test and replace the transducer if necessary. Check water and syrup flows and adjust if necessary, then check brix. Observe the Tank Transducer and replace if necessary. Test the relay board for 24VAC output and 5V...

What to do if product does not flow freely from FBD FBD553D?
- C
  Christopher AndersonAug 26, 2025
  If product from your FBD Beverage Dispenser does not flow freely, inspect the CO2 check valve and clean or replace if faulty. In "Manual On/Off", energize the CO2 and solution solenoid valves, checking for 24VAC at the coil, and clean or replace if necessary. If there are ice particles in the dispensing valve, run a defrost cycle, open and close the valve several times, or run warm water over it. Finally, check the water/syrup flow rates and brix, adjust the Level Control and Thaw/Freeze settings, and defrost the chamber, ensuring it's filled to 90% before pressing "Run".

What to do if my FBD Beverage Dispenser shows low water pressure?
- C
  cherylsuttonAug 27, 2025
  If you're experiencing low or no water pressure with your FBD Beverage Dispenser, first ensure the water is turned on and check for any restrictions in the line. Next, verify the CO2 is turned on and the "CO2 Press" readout displays 70-72 PSIG (482.6-496.4 KPa); adjust if needed. Check the "H2O Pressure" readout, and if it's not at 70-72 psi, check and replace the water pressure transducer if necessary. Lastly, check the water pump and replace it if it has failed.

How to fix a noisy condenser fan on my FBD Beverage Dispenser?
- D
  davisjosephAug 30, 2025
  To fix a noisy condenser fan on your FBD Beverage Dispenser, first check if the fan is contacting the condenser, fan blade guard, or any other part. Remove the fan guard and adjust the fan as needed, removing any obstructions. Reinstall the fan guard. If the fan blade is unbalanced, remove the fan guard and slide the fan blade weights to balance the fan, replacing the fan if necessary, and reinstall the fan guard. Finally, tighten any loose fan bracket fasteners.

What causes solenoids to not activate on FBD Beverage Dispenser?
- C
  Christopher WoodAug 31, 2025
  If the solenoids are not activating on your FBD Beverage Dispenser, check if the solenoid plunger is lifting by energizing the solenoid on and off in the “Manual On/Off” menu, checking for 24VAC at the coil, and clean or replace the solenoid if necessary. Test the solenoid relay on the Relay Board through the manual ON/OFF menu and replace if necessary. Ensure the connectors are clean and securely plugged in at the board and solenoid.

Why is my FBD FBD553D chamber not filling?
- T
  Troy BrownNov 22, 2025
  If the chamber of your FBD Beverage Dispenser is not filling, check the following: * Ensure the "Fill" button is pressed, and "Filling" or "Fill Hold" appears on the LCD display. * If the pressure in the chamber is above the refill point, gently pull the faceplate relief valve ring to relieve pressure. * If the unit is "Defrosting" or "Sleeping", press "Def" then "Run", and wait for the unit to freeze and the red light to go out. * Check the LCD messages for "Out of..." conditions, indicating a lack of CO2, syrup, or water. * Observe the "Tank Transducer" in "Readouts"; if the pressure isn't moving between 18 and 40 psi, or doesn't lower when chamber pressure is reduced, check and replace the transducer if needed. * If the CO2 solenoid valve won't open, energize the solenoid ...

Why does my FBD FBD553D have high head/suction pressure?
- J
  Jillian CombsSep 18, 2025
  High head/suction pressure in your FBD Beverage Dispenser can be caused by restricted condenser airflow; check for any restrictions and clean the condenser and air filter. Check the compressor amp draw. If the ambient temperature is too high, ensure the temperature surrounding the unit is less than 90°F.

What causes low head/suction pressure in FBD FBD553D Beverage Dispenser?
- J
  Joann TaylorSep 23, 2025
  Low head/suction pressure in your FBD Beverage Dispenser can be caused by a low refrigerant level. Check the compressor amp draw.

Why is the display door light out on my FBD Beverage Dispenser?
- J
  James HillSep 12, 2025
  If the display door light on your FBD Beverage Dispenser is out or flickering, the fluorescent tube may have failed and needs replacement. Check the inline fuse in the electrical box and inspect the wiring from the contactor, through the ballast, to the lamp connection, as a blown fuse could be the cause. If the fluorescent ballast has failed or is failing, it should be replaced.

How to address product leaking from the rear of the FBD Beverage Dispenser cold pack?
- R
  Regina GillSep 7, 2025
  If product is leaking from the rear of the cold pack on your FBD Beverage Dispenser, it could be due to a worn or damaged beater drive seal, which should be replaced with a new one. Alternatively, the beater drive coupling may be worn and require replacement. Lastly, ensure the seal is positioned correctly by reseating it from inside the chamber, making sure it is flush with the back of the chamber.
