Foam Brush not working

[Creekside Car Wash]

we just purchased our first car wash and the foam brush doesn’t work. No pressure, soap, or water. Nothing happens when you turn the dial to flaming brush at all. It worked a few months back when I patronized the car wash but now it doesn’t work at all. Help!!

Need more info. At the very least, post some pictures of the setup.

I meant the foam brush setup. The pumps the solenoids, the tank, whatever sends power to the pump if it's electric.
