Error #611, 612, 613: CO or Solution Leak
The barrel pressure is rising during a fill circuit diagnostic test.
Error #621, 622, 623: Barrel Leak
The barrel pressure is dropping during a fill circuit diagnostic test.
1
Determine if the barrel is filling with CO 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 voltmeter. If
12 VDC is measured on the CO solenoid or 24 VAC is measured on the solution solenoid then
replace the control board.
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 rmly seat.
4 Inspect the dispensing nozzle to determine if the leak is originating from it.
