I just installed our new toto toilet + total washlet 550e last weekend, after one use where everything was working, later that day the sprayer isn't working anymore, when I hit the button the wand comes out but doesn't spray and the pre-spritz function is no longer shooting out water either. I'm not sure how after installation the line is already clogged so wondering if anyone else has experienced this / has any trouble shooting suggestions, it doesn't seem to be an electronic issue with the controller since the wand is coming out.
