The Rainbow Autofoamer

[Soulmender]

Good morning gents, I have a The Rainbow Autofoamer triple foam. We are getting yellow buy not red nor blue. We have plenty of air, not drawing product from holding tank through pick up tubes. We have no air leaks, solonoids tested fine and the scrubbers in the bay are clean. It was working fine last week, now nothing other than yellow. The touchless automatic is a Hyrdrospray "P"ainmaker. Thanks
