I have an 8 bay self serve wash. My trifoam has stopped working in one bay. I've checked everything except the solenoids. Is this likely the cause? It works great in all the other bays.
Not sure how you have your equipment plumbed and wired but I would try pulling out the solenoid and plumbing straight through with a shutoff valve in its place to try and debunk my theory of bad solenoid before replacing.
