Soap in HP rinse

[Davidson]

I am getting what looks to be soap in my hp rinse in only 1 bay. What should I check first?

Maybe a bad solenoid if your soap is gravity fed into your HP line like mine is? Maybe the solenoid is hung open?

I second solenoid!!

I have a multi compartment tank and found the seal between compartments was no longer good.. If no solenoid issue and you have this setup . Fill rinse compartment and empty soap side and see if any water leaks thru.

Take solenoid apart and use a can of air on the components. Usually we have found a small piece of junk inside which was the issue.

The least likely thing would be the high pressure hose trapping some soap and releasing it on rinse. I've seen that happen a number of times.

Thanks for all the replies. It was debris in the solenoid.
