Funny you should say this because mine is doing the same thing BUT it happened about an hour ago when I washed my engine. I hope it doesnt mess up on me. I have washed the engine before the same way but I always try not to spray the filter (mine is a short ram AEM). Also, the other day I went through one of those drive through car washes and when it sprayed the undercarriage it did the same thing. I think I found the problem though. Before when I washed it I had my short ram into a coldair with the valve and it didnt do it. My guess would be to GET the bypass valve. It WILL save your engine.
