Question: Dewalt Dph3800-CHEM INJECTOR

steve r

I have a dewalt dph3800 pressure washer. On my job site yesterday it started spewing water out of the chemical injector (part #169 on the diagram) and back into the cleaning solution. I took it apart and inside I found a small broken o-ring. Bought a new o-ring but have no idea where to put it. My only guess is that the ball inside that valve is struck in the open position and all I need to do to get it working properly is replace that little o-ring in the correct spot. Where does it go? There's no diagram of the inside of part 169. Any ideas?

It goes in the top of the fitting the injector hose attaches to.
