Error #611, 612, 613, 614: CO2 or Solution Leak
The barrel pressure is rising during a fill circuit diagnostic test.
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. Replace a
leaking solenoid.
2 Ensure the solenoids are not manually turned on by going to the manual on/off menu. 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.
Error #621, 622, 623, 624: Barrel Leak
The barrel pressure is dropping during a fill circuit diagnostic test.
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.
Error #630: Refrigeration Pressure Transducer Offset
The pressure transducers were not reading correctly during the refrigeration diagnostic test.
1 Attach a set of refrigeration gauges that are known to be accurate and then compare the
gauges to the readings on the LCD. Replace the pressure transducer that is reading incorrect.
