Soap in Rinse water

I have a Jim Coleman pump stand and at one location and in only one bay, there is a small amount of soap when you are using rinse. I tried removing the soap, presoak and wax injection lines, but even then there is still some soap in the water. No soap in the rinse tank, it's completely clear and this only happens in that one bay. I even removed the tire cleaner to make sure it wasn't seeping into the rinse and still the same. Anyone know of how else soap could be getting into the HP rinse?
 
You need to check your soap, wax, and presoak solenoids for that bay and make sure one is not stuck open a little bit. Once you pull them apart give them a good cleaning and you should be good. If not there are repair kits available.

That was my first thought, so I ended up disconnecting all 3 and still had soap in the HP rinse.
 
There could still be soap, wax, or presoak drawing slowly in the lines. Check the solenoids tomorrow.
I did start by taking off all 3 solenoids and cleaning them. None looked damaged. Then when there was still soap, I took them off of the T under the holding tank so that nothing could be getting injected into the water. Let the bay run for a while and still had soap in the water. I can't think of anywhere else soap could be getting in, so doesn't make sense at all.

Disregard my last post. Correct if you took them off and let it run for a while there should be no soap.

That also eliminates any electrical issue with a solenoid too.

TBH I don’t see any other way soap can get in there. I edited my last post to ask if you’re using hot water specifically tankless. Reason is I’ve seen what looks like soap come out but it had something to do with tankless heaters. Can’t remember what. If you’re not using tankless then nothing to worry about.

No tankless, so can't be that. It's really weird. On HP wax it works fine. So just on HP rinse. No other way for soap to get in there. I figured it has to be soap or presoak and it still has to be somehow.
 
Keno has a great idea. Could be the hose. If you disconnected the soap from bottom feed of the tank then there is no way it's getting into the pump. The only other spot on the tank is the inlet through the hydrominder.
 
disconnect the main hose from the pump going out to the bay for high-pressure. Reconnect a new Shorter length hose with a gun assembly that you can pull out the door and spray from your equipment room. Test the rinse that way and see if it's OK that will tell you if it's the hose going out to the bay.
 
Does this bay have a different brand high pressure whose than the others? I have a similar problem and am using the Goodyear hose and I think soap has contaminated the line and a small residual amount is embedded in the lining leaking out during rinse.

Try swapping to wax for 30 seconds and back to soap and see if the soap goes away. That would confirm it's in the lines.

If contamination is suspected, I'd try strengthening the wax and switching to hard water rinse if practical. I also told my clean up people to wash down with HP wax.
