How to troubleshoot a 'CO2 or Solution Leak' on my FBD 772?

  To troubleshoot a 'CO2 or Solution Leak' on your FBD Beverage Dispenser: 1. Determine if the barrel is filling with CO2 or liquid. If the barrel liquid level is low enough use a flashlight to look at the back of the barrel and see if liquid is entering the barrel. 2. Replace a leaking solenoid. 3. Ensure the solenoids are not manually turned on by going to the manual on/off menu. 4. Check to see if either solenoid is receiving power by removing the leads and testing with a volt meter. If 12 VDC is measured on the CO2 solenoid or 24 VAC is measured on the solution solenoid then replace the control board, because the barrel pressure may be rising during a fill circuit diagnostic test.

  To troubleshoot a 'Barrel Leak' on your FBD Beverage Dispenser: 1. Look for any obvious leaks by searching for liquid along the product line from the solution module to the back of the barrel. 2. Inspect the rear seal to determine if the leak is originating from it. 3. Inspect the relief valve in the faceplate to determine if the leak is originating from it. Press and turn the relief valve to firmly seat. 4. Inspect the dispensing nozzle to determine if the leak is originating from it, because the barrel pressure may be dropping during a fill circuit diagnostic test.

What to do if the FBD Beverage Dispenser shows 'Syrup Out' error #011, 012, 013, 014?

  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.

  Veronica JohnsonSep 7, 2025
  If your FBD Beverage Dispenser shows error #020 indicating 'CO2 Out', it means the CO2 pressure is less than 45 PSIG (310 kPag). To resolve this: * Replace or refill the CO2 tank. * Ensure the CO2 shutoff valve at the back of the dispenser is not turned off. * Make sure the CO2 pressure transducer is properly connected and functioning. * Verify the CO2 supply pressure at the dispenser is reading 70 PSIG (483 kPag), and adjust the regulator if needed.
