No tire cleaner comiing from wand in only one bay

[metromanhvac]

Goodmorning, I have a 4 bay self serve wash, with a 8 postion rotary switch. All my functions were doing just fine. 4 days ago my tire cleaner in bay #1 stopped
coming out the high pressure wand. When tire cleaner is selected , I get air coming out but no product. Please advise me on what to check for and how to troubleshoot this problem.

Thanks in advance,

Start with the Floret and see if it is pumping.

I would put my money on the liquid solenoid for that bay. Use a screwdriver to check if it magnetized when turned on. That will check if it's getting power. Then take it apart and clean it. I just replace the entire bank when one goes bad.

If its just one bay that's not working, follow your polytubing out to the mixing block. Since you're getting air, it sounds like the tube for your chemicals might have split.
