Hey guys...
As a little background I just got through trouble-shooting a hardware issue. The thread particular to that issue can be found here: https://forum.arduino.cc/index.php?action=profile;area=showposts;u=505335
I mention this in-case my current issue is driven by that hardware issue I had yesterday. Diagram also included there.
Today I ran the device for a full cycle. This is the device idle for about 20 minutes and about 8 minutes of solenoid open time. After checking on the device- the LCD was hung up. I am thinking I'm either stuck in an endless loop or I have a variable that was not declared correctly and errors out the device.
Posting program code below. It should be noted the hang-up occurs during "draining" state. In this state the progress bar is ticking down slowly. It draws 4 rectangles, then 3, then 2 etc...
All ideas welcomed!
