Determine if the barrel is lling with gas or liquid. If the barrel liquid level is low enough, use a
ashlight 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 gas solenoid, or 24 VAC is measured on the solution solenoid, then replace
the control board.

Look for any obvious leaks by searching for liquid along the product line from the solution
module to the back of the barrel.
