One of my Ryko ultrasonics have the trifoam chemical leaking out during the whole wash. Is this a solenoid problem or something like that? If it is, is there a part number that needs replaced?
Yes it is a solenoid problem shut the bay down and take apart the solenoid it might just have some debris causing it to stay open sometimes it's a very simple fix.
It is the solenoid attached to the tri-foam lines on the OHD pump bench just follow the 3colors back to the brass manifold and a solenoid is attached to it, when unscrewing the seat from the solenoid have a bucket to catch any water that might come out. also besure not to lose the spring or the plunger inside the solenoid Ryko doesn't carry those parts.
