Factory Installed Black Tank Flush Problem

[Quick Step]

I tried flushing the black tank this weekend using the factory installed tank flusher on our 2015 Whitehawk and all I got was water flowing through the flusher without it spraying hard and it sounded kind of sounded like the water was flowing out of a garden hose without a sprayer attached to it. It has worked fine up until yesterday, anyone think a replacement is needed? I also took a picture of the inside of the black tank today, and yes the camera was sanitized afterwards, I was able to get a picture of the sprayer and it had a white spray head and the picture also showed the spray nozzles and everything looked clean without any debris clogging it. Is there something in these sprayers that could fail causing it not to spray and as we will be going out again next week I would like to get a replacement sprayer installed and was wondering if a quickie flush or something else would fit in the same hole as the one that is in there now?
