Scratching our heads here... Does anybody know how our foaming wax could possibly be getting into our spot-free rinse tank and/or how the spot-free application could start out "spot-free" on our Laser 4000's spot-free rinse cycle, but be spitting out foaming wax by the time it gets to the right rear quarter panel?
Already replaced o-rings in the check valves above the automatic bay. Attendant said he definitely noticed a pinkish hue in the spot-free tank earlier in the week, so he drained the tank. Tank is currently very clear with "a little bit of foam/bubbles" on the surface of the water.
Could something possibly "backfeed" into the spot-free tank???
Is there any place besides the manifold above the bay where wax could be getting mixed into the spot-free water?
