Air was coming out of the high pressure gun. This means that a low pressure solenoid is clogged up. I like my new air solenoid setup because you can turn off individual selections to figure out the problem. Then go directly to the correct solenoid bank.
I removed the magnet, then the plunger piece, then cleaned out everything.
This is a close up of the plunger thing.
I cleaned out the base, but it seemed clean. Everything worked fine after putting everything back together.
