Error #611, 612, 613: CO2 or Solution Leak
The barrel pressure is rising during a fill circuit diagnostic test.
Determine if the barrel is filling with CO2 or liquid. If the barrel liquid level is low enough use a
1 flashlight to look at the back of the barrel and see if liquid is entering the barrel. Replace a leaking
solenoid.
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 voltmeter. If
2
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: Barrel Leak
The barrel pressure is dropping during a fill circuit diagnostic test.
Look for any obvious leaks by searching for liquid along the product line from the solution
1
module to the back of the barrel.
2 Inspect the rear seal to determine if the leak is originating from it.
Inspect the relief valve in the faceplate to determine if the leak is originating from it. Press and turn
3
the relief valve to firmly seat.
4 Inspect the dispensing nozzle to determine if the leak is originating from it.
