Foamy brush issues

[Nick's Wonderwand]

I'm new to the carwash business.... and I have a 3 bay self serve. Bay 1 and 2 has great foam out of the foamy brush, bay 3 is all liquid. All air pressure is the same. Any ideas?

Make sure you have air at the brush. May have a leak or restriction before it gets to the brush.

If you have air as mentioned above next I would check your foam generator. Make sure it's clean and make sure something is in there to generate the foam.

I recently had the opposite, all air and no liquid. For us, it was the liquid solenoid coil that failed. Might be worth checking that the solenoid for air is working. Good luck!
