We had a similar problem with foam in our inline cleaner (TD). The problem were the solder paste flux residues. Boards went straight from SMT to Wave process and then washed. Anyway we changed the solder paste and problem solved. Are you using saponi

We just stepped into the inline wash world with a techical devices new clean galaxy plus. We are noticing a significant amount of foaming when washing our boards after selective solder. One theory is that the water soluble flux used is not being cu

We used to have a Nuclean 324 that was running closed loop with a DI water recirc system. We also had problems with foaming that was solved with a relatively simple fix. We bypassed the final rinse solenoid so that it was always running. This allo

Is this happening in the mornings? Are the operators allowing the machine to come up to set temperature before they run it?

I relate to your problem. We face this issue sometimes. It's mostly flux from SMT, TH process or rework boards. To avoid foam in our Washer, we soak the boards in hot water for 10-15 min before running it through the washer. Or you can spray the boar

Surely somewhere the cleaning or rinsing liquid gets to the other chamber. It is possible that the chemical migrates to the flush or flushes the chemical into the chamber. I have had a similar situation, high foam, injection vertical spray offline st

It has been happening in the mornings, and we do have a weak middle element, but our temp is always above 60C. we have it set at 65C. the service manager for the machine assured us that temperature wasn't the issue. Also, our flux application for ERS
